Description: Scientists aboard R/V Robert Conrad, led by Tom Aitken, collected single-channel analogue seismic reflection data during cruise RC0911A in 1965 with a 25 cubic-inch airgun and short hydrophone streamer. Despite their age, the data have good resolution. They reveal seismic stratigraphy within the Plio-Pleistocene sediments overlying the "S-reflection", which is commonly taken to mark the top of the Miocene evaporites in the Red Sea or perhaps a little above them. The data in places also reveal some of the uppermost layered Miocene evaporites, erosional unconformities at the S-reflection and possible salt diapirs. The sesimic profiles extend from the entrance to the Bab el Mandeb Strait in the Gulf of Aden to the Gulf of Suez. Data quality deteriorates towards the northern end of the transect. Electrical recordings from the hydrophone streamer were recorded in two channels onto paper (one with high amplifier gain and one with low amplifier gain). Navigation is unknown though likely combined celestial and dead-reckoning. The paper sheets were scanned by Neil Mitchell at Lamont in June 2014 with the help of Rose Anne Weissel. Individual data sheets were too big for the scanner (a 600 dpi Tokia photocopier). So, each sheet was scanned twice, covering both ends of each sheet. The dates are given at the base of each sheet and are in day-month-year format (with the month given in Roman numerals). Other annotation, such as times of vessel alter course (A/c) and coring stations, are also given at the base of each sheet. Annotated times are local, not UTC. The time offset appears to be 3 hours (ship time was 3 hours ahead of UTC). The time conversion may be chcked by comparing the seabed profile against that in GeoMapApp (the "Blue book" version of the data under Portals > "Analog Seismic Reflection Profiles" menu is correctly aligned) or against the bathymetry in MGD77 files. Horizontal lines on the sheets are at every 0.5 seconds of TWTT. These images are in JPEG image format (greyscale), and the files are in image pairs, labelled a and b, with one a/b pair corresponding to one seismic reflection data sheet. File names were generated by the scanner but are in numerical sequence. Hence, sorting the file names alphanumerically puts them in the same sequence as they were acquired during the seismic survey.

Description: A bathymetric survey using a Kongsberg EM124 echosounder was done along the Mid-Atlantic Ridge and its flanks between 50.2 and 51.5°S during the February 2023 R/V Roger Revelle cruise RR2301 (Chief Scientist: Tamara Russell). Survey lines were acquired at a typical vessel speed of ~9 kt (~4.6 m/s), with tracks spaced ~12 km to provide almost 100% bathymetric coverage. Adverse sea conditions during data acquisition caused a considerable number of ping artifacts due to vessel motion, which were removed manually on shore using QPS Qimera software. The final bathymetric grid was constructed using MB-System software at 100 m x 100 m node spacing. The grid is in GMT-compatible netCDF format. The survey was performed using UC Ship Funds.

Description: This data set consists of processed bathymetry grids collected by autonomous underwater vehicle (AUV) ABE (Autonomous Benthic Explorer) over the Kane Megamullion on the Mid-Atlantic Ridge during research cruise KN180-02 on R/V Knorr in 2004. AUV ABE was an experimental vehicle built by engineers at Woods Hole Oceanographic Institution (WHOI) and was eventually operated as part of National Deep Submergence Facility (NDSF) funded by the National Science Foundation (NSF). ABE was lost at sea in 2010. During Knorr cruise KN180-02, bathymetry was collected using a Simrad SM2000 high-resolution multibeam sonar mounted on ABE. The SM2000 is a 200khz, 180 degree swath-mapping system. Navigation was primarily by long-baseline (LBL) transponder and Doppler velocity log (DVL) where available. The raw multibeam files were processed and GMT-compatible netCDF format grids were created for those ABE dives that collected multibeam sonar data. The bathymetry acquisition was done under grant OCE-0118445 from the US National Science Foundation. DOI: 10.60521/331600

Description: The data set consists of a gas hydrate assessment using 120 petroleum industry wells in the North Carnarvon Basin, offshore Western Australia. Well data was downloaded from the Geoscience Australia database. The gas hydrate stability zone (HSZ) was identified for each well, based on bottom water temperature, bottom hole temperature and hydrostatic pressure. The presence of hydrate is evaluated using resistivity and gamma ray well logs. Some wells had additional data such as P-wave velocity and bulk density which was used when available. A background resistivity was identified or calculated for each hole and resistivity increases above background (0.5 ohm-m and above) were used to identify potential gas hydrate accumulations. The highest resistivities above background were categorized as "A" accumulations, and the lowest were categorized as "D", following the categorization of Majumdar et al., 2017 (Marine and Petroleum Geology). The data file is in Excel spreadsheet format, with column headers. The data set was generated as part the project called, Carbon storage in widespread low-saturation gas hydrate systems. Funding was provided from NSF CAREER award OCE17-52882. DOI: 10.60521/331592

Description: This data set is 30 processed SEG-Y files for high-resolution multichannel seismic reflection lines acquired by the U.S. Geological Survey Woods Hole Coastal and Marine Science Center in 2015 on R/V Endeavor, cruise EN555, with a towed sparker source. Processed CDP navigation has been written to the SEG-Y headers. The data were collected on lines oriented mostly down the continental slope from 100 to 2000 meters water depth or parallel to the continental shelf. The source was the USGS Woods Hole Applied Acoustics Delta Sparker attached to a surface-towed sled. The source was operated at 2.4 kJ and usually fired at 5 s intervals. Seismic reflections were recorded using the 72-channel Geometrics GeoEel liquid filled streamer (nine 50-m-long active sections; total length 555 m) with group spacing of 6.25 m and depth control using birds. For seismic navigation, the USGS used its own GPS equipment (Hemisphere antenna) mounted on the 01 deck. Positions were recorded using UTM zone 18N and the WGS84 datum. There was no GPS tail buoy on the streamer. Individual seismic shot data (SEG-D data and GPS coordinates) were recorded with Geometrics acquisition seismic software with 0.5 ms sampling and record length of 4.5 s. SEG-Y files sorted to CDP gathers were imported to the Seismic Unix seismic processing software, where various processing steps were completed. Using Matlab, the CDP coordinates were smoothed and the results written to the headers of these processed SEGY files. CDP positions have estimated uncertainty of 20 m along the line and 30 m perpendicular to the line. Detailed acquisition and processing parameters are described in the associated documents. Funding was provided to the USGS Gas Hydrates Project through DOE NETL interagency agreements DE-FE000291 and DE-FE0005806. DOI: 10.60521/331588

Description: This microseismicity catalog is derived from a single ocean-bottom seismometer on the Endeavour Segment of the Juan de Fuca ridge (network code NV, station code KEMF). The seismometer was installed on the Ocean Networks Canada NEPTUNE cabled observatory. Earthquake origin times, ranges (hypocentral distance between earthquake and seismometer), moments, and moment magnitudes are provided for earthquakes between 26 September 2011 and 31 May 2017. The data file is in ASCII format. The first row is a column header that describes the content of the catalog: origin time of the earthquake in unix format ('time'), the range to earthquake in km ('eventRange(km)'), the earthquake moment in dyne-cm ('eventMoment(dyne-cm)'), and the earthquake moment magnitude. Each line of the file corresponds to one earthquake. Not all earthquakes have an estimated moment due to selection criteria. Earthquakes occurring between June 2012 and June 2013 are excluded due to instrumental noise. Details of the methods used to create this catalog may be found in the Krauss, Z., Wilcock, W.S., & Baillard, C. paper, "A single-station earthquake catalog for the Endeavour segment of the Juan de Fuca ridge (2011-2016): challenges and implications for the spreading cycle". The data set was generated as part of the project titled "Microearthquakes on the Endeavour Segment, Juan de Fuca Ridge: A Near Real Time Earthquake Catalog for the ONC Cabled Observatory and a Reanalysis of Historical Data".

Description: Sediment samples were obtained with a Ponar grab sampler during R/V Lowell Weicker surveys of western Long Island Sound in June 2023. The sampling was done as part of the Long Island Sound mapping project Phase 3A. Two GoPro video cameras mounted to the frame of the Ponar sediment grab device were used to capture video of the seafloor to help characterise its nature at the location of the grab samples. One video camera looked forward, the second looked straight down. Diving lights were used to illuminate the bottom. At some stations one of the two camera failed to record a suitable video due to battery or other problems. Also, the three stations on the first day were recorded only with the bottom-looking camera. These still images are in JPEG format and were extracted by Chris Conroy as frame grabs from the video when the seafloor was showing the clearest. For geographical location, the images where tagged with the location recorded for the sediment grab station which is based on the ship DGPS system. The bottom images were collected to provide a better overview of the actual seafloor from which the grab samples are taken. They also allow the seafloor character to be classified when a grab sample could not be recovered, e.g. when the bottom was too hard or consisted of exposed rocks. This project was made possible by the Long Island Sound Research and Restoration Fund, established by a Memorandum of Understanding among the members of the Policy Committee of the Long Island Sound Management Conference and administered by Long Island Sound Cable Fund Steering Committee.

Description: Sediment samples were obtained with a Ponar grab sampler during R/V Lowell Weicker surveys of western Long Island Sound in June 2023. The sampling was done as part of the Long Island Sound mapping project Phase 3A. After the sediment grab sampler was retrieved on the surface, each side of the grab sampler was photographed. The images of the two sides of each sample are labeled A and B. The photographs are in Geo-tagged JPEG image format. For geographical location, the images where tagged with the location recorded for the sediment grab station which is based on the ship DGPS system. The surface photos were collected to provide a better overview of the in-situ sample from which a sub-sample was taken for later analysis. The photos also record any shells, rocks and pebbles that might be excluded from later analysis. This project was made possible by the Long Island Sound Research and Restoration Fund, established by a Memorandum of Understanding among the members of the Policy Committee of the Long Island Sound Management Conference and administered by Long Island Sound Cable Fund Steering Committee.

Description: This data set consists of raw multi-channel seismic reflection (MCS) data in SEG-Y format, collected in July 2022 along the continental slope of the Campeche Bank aboard R/V Justo Sierra. The research objective was to map the detailed stratigraphy of sediment drift deposits to explore the history of the Loop Current and its climatic implications. We used the portable high-resolution seismic acquisition system operated by Scripps Institution of Oceanography, which comprised a source array of two 45 cubic inches G.I. air-guns and a GeoEel streamer with 120 channels at a spacing of 6.25 m. The air-gun array was fired every 12.5 m and was towed at a depth of 3 m. Data was recorded using the Geometrics seismic recording system with sample rate of 0.5 ms and recording length of 4 ms. A 50-ms delay was created during each shot as a buffer between the timing pulse that starts the recording and the trigger pulse that fires the air-guns. A total of 11 seismic lines were acquired including two long strike lines, five dip lines, two tilted dip lines and two short transition lines. The shot spacing was not exactly 12.5 m during the first three lines (1001-1003) due to system glitches, therefore, it is necessary to merge navigation with SEG-Y headers to ensure accurate processing of these lines. Detailed acquisition parameters and cruise incidents are described in the associated documents. Funding for this work was provided through NSF awards OCE-1928888 and OCE-1450528, and CONTEX award 2018-38A. DOI: 10.26022/IEDA/331509

Description: This data set consists of raw high-resolution multi-channel seismic reflection (MCS) field data collected in 2021 over the Vitoria Trindade Ridge and Columbia Channel during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. The MCS data was acquired using a sparker seismic source with 800 tips model Geo-Source 800, up to 7 kJ energy power supply (GeoSpark 2000X) and a 48-channel streamer, all from the Geo Marine Survey Systems. Seismic acquisition and SEG-Y conversion was performed with the GeoRecorder software, also from Geo Marine Survey Systems. The Geo-Source 800 used a negative discharge for seismic pulse generation which results in a more stable seismic signature with a frequency range between 200 – 3000 Hz, centered at ~1 kHz. The streamer was composed of three hydrophones per channel, with a total active length of 150 m and 2 x 25 m cable stretches, to make a total of 200 m of streamer deployment. Channel distance in the streamer is 3.125 m and channel sampling occurred at 10 kHz. Geographic geometry was supplied by a DGPS antenna placed atop the seismic source configured with the WGS-84 ellipsoid and UTM projection zone 23S. Geometry distance averaged 5 m between source and streamer (dx) and ~20 m between source and first channel (dy). The source was placed at 1.5 m water depth and the streamer was at 0.5 m water depth. Energy levels and trigger interval for pulse generation varied across the survey depending on the bathymetric profile. Vessel velocity during seismic acquisition averaged 4 knots. See additional information in the associated Methodology report. These raw field MCS files are in SEG-Y format. Funding for this work was provided through FAPESP awards 2016/24946-9 and 2020/08847-6, and through the Brazilian Navy program PROAMAZONIA AZUL. DOI: 10.26022/IEDA/331494

Energy levels and trigger interval for pulse generation varied across the survey depending on the bathymetric profile. Vessel velocity during seismic acquisition averaged 4 knots. Seismic processing was performed with the RadExPro software, v2022.1. Basic brutestack seismic processing was made for all seismic lines, following these steps: quality control (data filtering), preprocessing (noise filtering), geometry evaluation, normal move-out correction and stacking. For Lines L01 and L17 enhanced seismic processing was performed, including the following additional processing steps: static correction, deconvolution, multiple suppression and migration. Band-pass filtering was performed between 200 – 1500 Hz. For stacking, common mid points (CMD) gathers were established. See additional information in the associated Methodology report. The processed MCS files are in SEG-Y format. Funding for this work was provided through FAPESP awards 2016/24946-9 and 2020/08847-6, and through the Brazilian Navy program PROAMAZONIA AZUL.

Description: This data set consists of sub-bottom profiler data collected in 2021 over the Vitoria Trindade Ridge and Columbia Channel during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. The high-resolution sub-bottom data was acquired with a hull-mounted Kongsberg SBP-120 CHIRP system. Survey geometry came from a SeaPath 330 positioning system with two GNSS antennas without differential positioning. Acquisition occurred in the Kongsberg SIS software with the ellipsoid WGS-84 and a UTM projection and zone 23S. The equipment was operated with one main channel, in a frequency of 2.5-6.5 kHz, with chirp up linear pulse, which results in a maximum vertical resolution ~0.3 ms. The data was logged in Topas raw format and converted to SEG-Y format. The power of the SBP pulse and trigger interval varied along the survey depending on ocean conditions and seafloor depth. Seismic data was then converted from time to depth assuming a sound speed of 1500 m/s. Ship survey speeds ranged from 4-7 knots. The files are in SEG-Y format.

Description: This data set presents photographs of sediment samples collected in 2021 over the Vitoria Trindade Ridge during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. During the sampling program, nine seafloor sediment samples were collected within the Vitória-Trindade Ridge with a Van-Veen grab sampler (3600 cm²) on the top of the volcanic seamounts. Sample V7 collected only rhodoliths, without additional sediments. Samples were washed, dried, weighed, sieved, and analysed. The photographs are in JPEG image format. For the analysis, each seafloor sample was subdivided into ten subsamples (Q number). Codes: V# - Number of Sample (_# goes when there is multiple images for the same sample); Q# - Number of the quartile sample (only for the biofacies).

Description: This data set presents sediment sample data consisting of biofacies abundance and sediment grain size and properties for samples collected in 2021 over the Vitoria Trindade Ridge during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. During the sampling program, nine seafloor sediment samples were collected within the Vitória-Trindade Ridge with a Van-Veen grab sampler (3600 cm²) on the top of the volcanic seamounts. Sample V7 collected only rhodoliths, without additional sediments. Grain sizes larger than 40 mm diameter (pebble size) were separated for rhodolith measurements. Sediment samples were washed to dissolve the salt concentration for 48 hours, then oven-dried at 45 °C for 72 hours. The rhodolith samples were dried at 35 °C for 48 hours. The morphometry of the rhodoliths was classified in spheirodal, discoidal and ellipsoidal based on the measurement of the long (L), intermediate (I) and short (S) axis with a Vernier Caliper. Samples were weighed and sieved in phi fractions (-1.5, -1.0, -0.5, 0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0 and > 4.0) for 10 minutes. Samples sieved were described in phi fractions and were grouped in the following orders: granules (-2 to -1), very coarse sand (-1 to 0), coarse sand (0 to 1), medium sand (1 to 2), fine sand (2 to 3), very fine sand (3 to 4) and silt (> 4). The mean grain size and sorting were analyzed on Gradistat v9.1 software. Sediment samples were also placed on a Petri dish for microscope analysis and photography using Fiji software. Grains were then classified (Carbonate debris, foraminifers, bryozoans, sponge spicules, bivalves, gastropods, crustaceans, echinoderms, and annelida) and abundance was quantified based on 300 random point counts per sample. The data file is in Excel spreadsheet format. In the file names, SS = "Seafloor Samples". For the analysis, each seafloor sample was subdivided into ten subsamples (Q number). Codes: V# - Number of Sample (_# goes when there is multiple images for the same sample); Q# - Number of the quartile sample (only for the biofacies).

Description: This data set consists of sound velocity data collected in 2021 over the Vitoria Trindade Ridge and Columbia Channel during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. To estimate sound velocity profiles for bathymetric processing, temperature profiles were first obtained for the water column throughout the survey every 50 nautical miles, for a total of 31 profiles. For that we used Expendable Bathythermograph (XBT) Lockheed Martin model T5 for the deeper portion of the survey (down to 1860 m water depth) and the model T7 over the shallower regions (down to 760 m). A salinity profile was then calculated by linearly interpolating the measured temperature profile to the nearest WOA/RTOFS salinity profile. Sound speed values were then calculated from the salinity updated profile using the UNESCO equation. The data file is in ASCII format. Funding for this work was provided through FAPESP awards 2016/24946-9 and 2020/08847-6, and through the Brazilian Navy program PROAMAZONIA AZUL. DOI: 10.26022/IEDA/331480

Description: This processed swath bathymetry data set was collected in 2021 over the Vitoria Trindade Ridge and Columbia Channel during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. The data files are in MB-System-compatible GSF format (mbio format 121) and contain processed swath bathymetry and acoustic backscatter data. The multibeam bathymetry was collected with the Kongsberg EM-122 deep echo-sounder operating at a frequency of 12 kHz. The system was coupled with the SeaPath 330 positioning system with two GNSS antennas. Acquisition occurred in the Kongsberg SIS software with the ellipsoid WGS-84 and UTM projection. Swath width was to set to be up to 55° with a ping frequency of 40 Hz. Due to the deep characteristics of the EM-122 equipment, multibeam bathymetry was not performed in water depths shallow than 200 m. To estimate sound velocity profiles for bathymetric processing, temperature profiles were first obtained for the water column throughout the survey every 50 nautical miles, for a total of 31 profiles. For that we used Expendable Bathythermograph (XBT) Lockheed Martin model T5 to the deeper portion of the survey (down to 1860 m water depth) and the model T7 over the shallower regions (down to 760 m). A salinity profile was then calculated by linearly interpolating the measured temperature profile to the nearest WOA/RTOFS salinity profile. Sound speed values were then calculated from the salinity updated profile using the UNESCO equation. Sound velocities were then incorporated during the multibeam bathymetry acquisition directly into the SIS software.Multibeam bathymetry preprocessing was performed using the CARIS HIPS software from Teledyne during the cruise. A Patch Test calibration of the echo-sounder was done atop the Columbia Seamount on October 26th on where roll, pitch, yaw, heading and the time delay were calibrated. The corrected values from the Patch Test were then inserted on the processing procedure. Survey velocity range between 4-7 knots. Finally, spike removal and surface equalization processing were performed with the software EIVA NaviModel Producer after the survey.

Description: This data set consists of processed magnetic data collected in 2021 over the Vitoria Trindade Ridge and Columbia Channel during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. A SeaSPY magnetometer from Marine Magnetics was used to acquire the magnetic field data. The sensor (torpedo) was towed 250 meters from the vessel and 300 meters from the vessel GPS antenna, and was towed about 30 to 35 meters below the sea level. The SeaSPY magnetometer is a Proton Precession (Overhauser) sensor of absolute accuracy, and the resolution of the system is 0.1 nT and 0.001 nT, respectively. The data was acquired in a 10 Hz frequency, from the continental slope to the furthest point from the continent, nearby the Trindade Island. The frequency resulted in measurements for every meter traveled, on average, considering the variable ship speed between four and seven knots. The survey also occurred in parallel to the seismic survey, without any perceptible interference. The data file is in ASCII format with header lines.

Description: This data set presents processed Multi-Channel Seismic (MCS) reflection data acquired during the Juan de Fuca (JdF) Ridge-to-Trench experiment conducted in 2012. In this experiment two ridge-to-trench transects across the Juan de Fuca plate, from Endeavour Ridge to offshore Washington state and from Axial Volcano to offshore Oregon state, and one 400 km-long trench-parallel transect extending from 44.3N to 47.8N were acquired during the 2012 R/V Langseth survey MGL1211. The seismic reflection images of the two ridge-to-trench transects reveal the sediment stratigraphy and crustal structure across the JdF plate and just seaward of the Cascadia deformation front. The files in this data set are pre-stack depth-migrated reflection stacks with advanced processing routines applied and were processed along with the CASIE21 data set. Details of the processing work flow are described in the linked data processing document. The data files are in SEG-Y format. Funding for original data acquisition was provided through NSF grants OCE 1029411 and 1029305. Results from this study are described in Carbotte et al., Science Advances, 2024. DOI: 10.60521/331457

Description: Along the Polish coast of the Baltic Sea, Puck Lagoon provides the most valuable benthic habitats. Despite this, the area previously lacked high-resolution bathymetry and backscatter data sets which are essential for enhancing our understanding of this biodiverse area. To address the lack of data, a new project called "The pioneering exploration of the Puck Lagoon based on high-resolution airborne and acoustic remote sensing" set out to collect the first comprehensive set of marine and aerial measurements of the seafloor covering the entire lagoon.​​​​​ The project is part of the National Science Centre SONATINA 5 research programme. This data set presents a range of bathymetry and remote sensing data generated as part of the project. There are seven GeoTIFF grids and one GeoTIFF image. The GeoTIFF grids are referenced in PL-EVRF2007-NH vertical system and UTM-34N projected coordinate system based on the ETRS89 ellipsoid. The majority of the files are named from the measuring source used for acquisition, as follows. The MBES_DEM and MBES_BSS grids represent digital elevation model (bathymetry) and backscatter of the acoustic signal acquired with Teledyne Reson T50/T20 multibeam echo-sounders. The LIDAR_DEM and LIDAR_INTENSITY grids represent the digital elevation model and intensity of the laser signal, respectively, from an airborne bathymetric LiDAR Riegl VQ-880-GII instrument. The PHOTO_DEM grid provides a digital elevation model derived after treating airborne photographs with Structure from Motion (SfM) techniques and then using the DepthLearn algorithm to correct for water refraction. The photographs were acquired with two PhaseOne iXM-100 airborne photogrammetry cameras. The ORTHOPHOTO GeoTIFF image represents an ortho-rectified image of the research area. The INTEGRATED_DEM grid was generated artificially by unification of digital elevation models from the multibeam echo-sounders and bathymetric LiDAR. The SDB grid shows Satellite-Derived Bathymetry (SBD) for the research area generated from SPOT-6 satellite imagery. All grids and the ortho-rectified image have a pixel size resolution of 0.2 m except for the SDB grid that has coarser cell resolution, approximately 5x8 m. Spatially, the study site covers an area of approximately 103 km2 but, depending on the method used, the coverage of each data type is different. This research was funded by grant number 2021/40/C/ST10/00240 from the National Science Centre, Poland. The contribution of Dr. Panagiotis Agrafiotis is part of the MagicBathy project funded by the European Union HORIZON research and innovation programme under Marie Sklodowska-Curie grant agreement number 101063294.

Description: This data set consists of Deep Tow vehicle navigation files for Galapagos Spreading Centre 1972 cruise SOTW06WT. These ASCII navigation files were generated by Neil Mitchell at the University of Manchester as follows. According to Klitgord & Mudie (1974), a network of six bottom transponders was originally deployed for the survey. Acoustic ranging between them, the Deep Tow vehicle and the ship enabled their relative positions to be calculated for most of the survey duration, with an internal accuracy of ~40 m. For the remaining one-third of the survey, it is unclear how the vehicle position was calculated although a cable trajectory model is mentioned in Klitgord and Mudie (1974) for a line over the northerly flank, which may have been used more widely. In addition, satellite fixes of the vessel allowed the survey to be placed in a geographic framework with an accuracy of ~0.5 km (after digitising accuracy is included, position accuracy will be somewhat poorer than this). A vehicle track map originally produced by Bob Detrick was digitised to generate (x, y, survey time) and these values were merged with digital data files obtained from the Marine Physical Laboratory at Scripps Institution of Oceanography to produce (x, y, Deep Tow vehicle depth, bathymetry at the Deep Tow position, survey time). The navigation files presented here contain these positional values updated with geographical coordinates that were obtained from longitude = X * 7.963700000000E-06 - 86.179455500; latitude = Y * 8.728372093023E-06 + 0.56179069767, where X and Y are the local coordinates in meters. That is, a flat-Earth approximation is used and is justified given the small geographical area and the age of the data (position uncertainty is larger than projection error). The X and Y values are also in the files. DOI: 10.26022/IEDA/331450

Description: In an R/V Thomas Washington survey in 1972, South Tow, leg 6 - SOTW06WT, the Scripps Deep Tow vehicle was deployed over the Galapagos Spreading Centre, covering an area 24 X 50 km including the ridge crest. The vehicle was towed close to the seabed at an altitude of only 130 m on average so that the paper records from the Deep Tow 4 kHz sediment profiler have good vertical resolution. The seabed and basement topography are useful for revealing fault escarpments. Also, if deposition of pelagic sediments is not significantly moderated by bottom currents or other mechanisms, their thickness can potentially be useful to date the underlying basement. Such may be true of the Galapagos Spreading Centre in the Panama Basin which lies close to the equatorial high pelagic productivity belt. Cores show the sediment to be a siliceous-calcareous ooze. The seabed and basement reflections were digitised from A4-sized paper copies of the 4 kHz reflection data, each corresponding to roughly a half-hour duration of the survey. The digitised values were interpolated in survey time to provide coincident values (i.e., two-way seismic time to both reflections at fixed survey time intervals). Two-way times were converted to depths using seismic velocities of 1500 and 1553 m/s for seawater and sediments, respectively. Those interpolated depth values were then merged with navigation (see associated Deep Tow vehicle navigation data set under the "Related Data" links on the right and under the "Related Data Sets" tab on the left) to provide profiles of seabed and basement elevations as well as sediment thickness. Depths to the basement and seabed for each file (corresponding to each A4-sized paper copy) were offset vertically so that the seabed depth coincided in a least-squares sense with the bathymetry column in the associated navigation files. Hence, basement and seabed depths are relative to the ocean surface. These files are in ASCII format and include a header line. DOI: 10.26022/IEDA/331451

Description: This heat flow data set was acquired during R/V Roger Revelle cruises RR1901 and RR1902 conducted in 2019 as part of the project called SAFFRONZ: Slow-Slip and Fluid Flow Response Offshore New Zealand - Probing the Nature of the Hikurangi Margin Hydrogeochemical System. Fluid generation, migration, and pore pressure at subduction zones are hypothesized to exert a primary control on the generation of seismicity, low-frequency earthquakes and slow slip events (SSEs). The Hikurangi margin (east coast of North Island, New Zealand) exhibits dramatic changes in the along-strike depth distribution of SSEs, depth of interseismic coupling, inferred pore pressure, and other subduction-related parameters. In 2019, in-situ measurements of thermal gradient and thermal conductivity were collected using the Oregon State University 3.5-m violin-style multi-penetration heat flow probe. In most cases seeps were targeted to document advective heat flow, if any. The thermistor string houses 11 thermistors and measures both the in-situ thermal gradient and thermal conductivity that are combined to determine the heat flow. On most measurements the probe position was determined with ultra-short baseline telemetry (USBL). The data was processed using SlugHeat (https://marine-heatflow.ceoas.oregonstate.edu/software/). The data file is in Excel spreadsheet format, with column headers. Funding was provided by NSF grants OCE17-53665 and OCE17-53617. DOI: 10.26022/IEDA/331405

Description: The top of the Miocene evaporites throughout most of the Red Sea is marked by a prominent reflection in seismic data, called the "S-reflector" in the literature. The topography of this reflection can potentially reveal how the Miocene evaporites have moved since they were deposited. The thicknesses of the Plio-Pleistocene sediments above the evaporites may also reveal how subsided areas of the Miocene evaporites have been filled with sediment, as well as effects of sediment transport within the basin and sediment supply. The S-reflector is imaged in seismic data, including in early single-channel seismic data from the 1960s. This data set presents grids of seismically-derived thicknesses of Plio-Pleistocene sediments and depths to the top of the Miocene S-reflection in the Red Sea. Six grids are provided here. All are in GMT COARDS-compliant netCDF format and are in geographic coordinates. Four of these grids cover a large area and have file names starting with "redsea_Depth_S_reflection" or with "redsea_PlioPleistoceneThickness". The remaining two grids are derived from 3-D multi-channel seismic data and have names beginning "3DSeismicPP" where PP stands for Plio-Pleistocene. The four large-area grids were produced as follows. The seismic two-way times to the seabed and S-reflection were digitised from data of varying quality from 17 research cruises and from one commercial 3-D seismic survey. The quality of the seismic data varied, including line-drawing interpretations, paper records, and modern digital records. Two-way times were converted to depths below sea-level using 1538 m/s and 1900 m/s for the water column and Plio-Pleistocene sediments, respectively. Navigational accuracy reflects the positional technology in use during the surveys and varied from transit satellites in the 1960s to 1970s to GPS from the late 1980s onwards (details are available in the headers of the track line data for these earlier cruises from ncei.noaa.gov). Nevertheless, the accuracy even for the earliest cruises was considered adequate due to the coarse nature of the mapping done in this study. Each cruise file of the results (S-reflection depth and Plio-Pleistocene thickness) was first binned within cells of 0.01° X 0.01° to ensure relatively uniform along-track data density. Those cruise files were subsequently combined and binned again with a cell size of 0.1° X 0.1°. Grids were then generated using the GMT program "surface" with a tension factor of 0.35. In the "interpolated" grids, grid nodes that were more than 0.15° geographical degrees (~16 km) from measurements (of S-reflection depth or sediment thickness) were masked out (i.e., set to NaN). The "not_interpolated" grids were similarly constructed, though with grid nodes more than 0.015° (~1.6 km) from measurements masked out. Hence, these are like the interpolated grids but give a better sense of where the measurements were made, at the expense of being less useful for visualising variations. Finally, any areas of data overlapping with geomorphology that in multibeam sonar data was interpreted as volcanic (e.g., cones, ridges) were masked out (set to NaN). Further details are given in the associated references. The remaining two grids derived from 3-D seismic data give more detail of S-reflection depth and thickness of the Plio-Pleistocene sediments. These two grids were derived from commercial 3-D multi-channel seismic reflection data originally collected for BG in 1999. There is little information on the original processing of the commercial seismic data, although it extended to time migration. The 3-D volume comprises 4879 crosslines (SW-NE) spaced 12.5 m apart and 1729 in-lines (SE-NW) spaced 25 m apart. The seismic data have good quality above the Miocene evaporites and the S-reflection is clear throughout the volume. The seabed and S-reflections were mapped out using the geological interpretation software IHS Kingdom. For consistency with the large-scale grids, the same velocities of 1538 m/s and 1900 m/s for water column and sediments have been used to compute S-reflection depths and Plio-Pleistocene sediment thicknesses. More details are given in the associated references. DOI: 10.26022/IEDA/331395

Description: Residual mantle Bouguer anomaly grid calculated for the Ohana project located 25-30.5°N, 145.5-137.5°W in the NE Pacific. This ~500x600 km area was the site of an Ocean Bottom Seismometer array deployed Nov 2021-Feb 2023 by a team led by Gabi Laske. Donna Blackman led the bathymetric and gravity analyses. Gravity data processing started with the satellite-based Free Air Anomaly grid (grav_32.1.nc, Sandwell et al., 2014). The contributions of seafloor topography (from the corresponding bathymetry grid called Ohana_bathymetry_200m_v5n.grd), and of a constant thickness (6 km) crust were removed assuming 1700, 250, and 350 kg/m3 density contrasts at the seafloor, upper/lower crust (1.5 km depth), and basal interfaces, respectively. The best-fit exponential age trend of the predicted mantle Bouguer anomaly was removed as an estimate of the contribution of plate cooling for this 40-52 Ma area. The resultant RMBA data was gridded at 200 m. The RMBA data file is in GMT-compatible netCDF grid format. DOI: 10.26022/IEDA/331358

Description: Bathymetry grid produced as an add-on to the Ohana project. This grid covers 30.5-32.5°N, 134.5-132 °W in the NE Pacific which is to the east of the main Ohana project area. This smaller eastern area was mapped during R/V Sally Ride cruise SR2302 following Ocean Bottom Seismometer array recovery in February 2023 by a team led by Gabi Laske. Donna Blackman led the bathymetry processing and Su Talavera-Soza and Ruei-jiun Hung contributed. Detailed processing for cruise SR2302 was done manually with MB-System mbedit. Hull-mounted multibeam bathymetry data from 5 additional cruises available at NCEI as of January 2023 were compiled with the processed SR2302 multibeam data. All data were gridded at 200 m using mbgrid. The data file is in GMT-compatible netCDF grid format. DOI: 10.26022/IEDA/331357

Description: Shipboard free-air gravity data were processed in the same way as described by Wang et al. (2015) to obtain Residual Mantle Bouguer Anomaly (RMBA): The gravitational effects of seafloor topography and relief on the crust-mantle interface were subtracted from the free-air gravity anomaly to obtain mantle Bouguer anomaly (MBA), assuming a reference crustal thickness of 6 km and using the spectrum method of Parker (1973). Densities of water, crust, and mantle were assumed to be 1.03 10^3, 2.7 10^3, and 3.3 10^3 kg m^-3, respectively. RMBA was then calculated by removing the gravitational effect of lithospheric cooling from MBA, based on a 3-D mantle thermal model. The mantle thermal structure was calculated for a 100 km thick layer, using the 2-D age grid of Wang et al. (2015) and assuming simple 1-D plate cooling (Turcotte and Schubert, 2002; Wang et al., 2011). The parameters used in the calculation are the same as in Wang et al. (2011). This mantle thermal model was then converted to a 3-D mantle density structure, which was used to calculate gravitational effects. The data file is in GMT-compatible netCDF grid format.

Description: There are 28 Multi-Channel Seismic lines, collected in 1986/87 across the Central and South Basins of the Lake Malawi Rift as part of the PROBE project (Proto-Rifts and Oceanic Basin Evolution) of Duke University. All files are in SEG-Y format, with coordinate reference system and navigation information in the headers. The projection is UTM-36S. The record length is 6 seconds two-way travel time, 4 ms sample rate. Profiles are generally oriented east-west across multiple rift segments. Data were acquired aboard R/V Nyanja, a 36-foot-long dedicated geophysical vessel transportable by cargo aircraft. Source was a single 140 cubic inch EERI airgun, or 3x40 cubic inch array of GSI sleeve guns. Streamer was a GECO custom-built 960 m active-length cable comprising 48 groups (20 m group interval); lead-in cable length varied from 250-440 m. Streamer depth was nominally 10 m and controlled a buoy suspension system. Fold coverage was nominally 24-fold. Acquisition was via Texas Instruments DFS-V, at 2 ms sample rate. Navigation was by transit satellite, radar, automatic speed log and deduced reckoning. Navigational accuracy ranges from <100 m to several km in places. Every line is controlled by a minimum of two fixes and a 40-80 km line is controlled by 5-8 good fixes. Chief Scientist was Bruce R. Rosendahl. Data were recovered from 9-track tape and archived on modern media under the supervision of Christopher A. Scholz, Syracuse University. Legacy time processing at Duke University was completed with Digicon DISCO 50 software on a DEC VAX 11/750 computer, applying the following workflow: Demultiplexing, Resample, Geometry Definition, Trace Edit, Sort, Deconvolution, Filter, Velocity Analysis, Stacking, Mute, Migration, Display. Deconvolution is a predictive gap deconvolution, occasionally spiking deconvolution is used. Filtering was variable, typically a bandpass filter with a Hanning taper was employed with typical cutoffs of 6-10 Hz at the low end, and 50-55 Hz at the upper end. Some lines received time-variant filtering and occasionally notch filters were used. Select lines were subjected to a post-stack finite difference time migration routine. Funding for data collection and processing was from multiple 1980s-era oil and gas companies. DOI: 10.26022/IEDA/331340

Description: There are 25 Single-Channel Seismic Lines that are confined to the North, Central, and South Basins of the Lake Malawi Rift. These were collected in 2001 as part of the Lake Malawi Sub-Lacustrine Fan Study with support from Syracuse University industrial associates. All files are in SEG-Y format, with coordinate reference system and navigation information in the headers. Record length is three seconds two-way travel time, 0.5 ms sample rate. Profiles are generally oriented north-south (strike), or east-west (dip). Data were acquired aboard R/V Ndunduma, an 18-meter-long vessel of opportunity operated by the Malawi Department of Fisheries. Chief Scientist was Christopher A. Scholz. Line spacing is variable. Source was a 10 in3 and 20 in3 Bolt 600B airgun — 2000 psi. Receiver was a S.I.G. 10 m 16 hydrophone element streamer. Acquisition was via a Elics-Delph 2 at a 0.5 ms sample rate. Navigational data was acquired with Continuous Autonomous GPS. Data bandwidth is 50-450 Hz. General processing at Syracuse University was performed using Promax software with the following workflow: 3–trace horizontal stack, band-pass filter (80–500 Hz), 100 ms AGC, trace balancing.

Description: The data set consists of a 3-D full-waveform inversion (FWI) model of compressional velocities within the upper crust beneath the East Pacific Rise 9º50'N. The velocity model was obtained using 3-D multi-channel seismic data collected in 2008 during the MGL0812 experiment aboard R/V Marcus G. Langseth (PIs: John Mutter, Suzanne Carbotte). We use ~90 000 shot gathers; Only mid-to-far source-receiver offsets (2-6 km) are included in the inversion. The final velocity model is obtained after 15 iterations using frequencies up to 7 Hz. The details on the inversion parameters and modeling are provided in Marjanović et al. (2018). The model is provided as an ASCII file. The size of the grid is 441 x 551 x 200 (x,y,z) grid points with the horizontal and vertical spacing 100 m and 25 m, respectively. The origin of the grids is Easting=562090; Northing=1045620; UTM Zone=13; Azimuth of the 3-D box =8º. This velocity model work was funded by Marie S. Curie Individual Fellowship (No: 655283 3DWISE).

Description: This data set presents EM124 shipboard multibeam data from various locations around and on the Galapagos Platform, collected during R/V Atlantis leg AT50-09BC in April 2023 that included 22 Alvin HOV dives. The multibeam data were acquired to fill in areas where previous mapping around the Platform, carried out in 2000, 2001 and 2010, was incomplete, and to serve as base maps to plan and execute Alvin dives. The AT50-09BC expedition is a collaborative project between UK and USA scientists at U. Bristol, U. Essex, Boise State U. and Woods Hole Oceanographic Institution (WHOI). The objective of this multidisciplinary research is to investigate the shallow and deeper portions of the Galapagos Platform to better understand the geological evolution of this important volcanic archipelago and the biological and climate records contained in the fauna. The project is funded through research grants from the Natural Environment Research Council in the UK, and from the Ocean Sciences Division of the National Science Foundation in the USA.Bathymetric mapping was a major component of the activities of the expedition as accurate maps were essential in dive planning and in dive site selection (see site maps with each dive summary in the cruise report). The multibeam data collection, quality control, data processing, and ping editing were undertaken by many members of the science team as part of regular watch-standing shifts and was headed by Shannon Hoy from NOAA-Ocean Exploration, who led the production of final map products and the compiled dive maps. Both QPS Qimera and Fledermaus were used for multibeam processing, editing, and visualization. ArcGIS and Fledermaus were used for compiling map data and planning dive traverses. Areas mapped included the following totals: Costa Rica EEZ (during transit) = 5019 km2; Ecuadorian EEZ = 19,055 km2; Area mapped inside the Galapagos National Park = 16,796 km2. Total seafloor mapped = 24,074 km2 (approximately the size of Rwanda or New Hampshire). The data files are in GeoTIFF image format. DOI: 10.26022/IEDA/331317

Description: RMBA anomalies were digitized from Maia and Gente (1998) and used by Cann et al. (2015) to interpret the tectonic evolution of 200 km of Mid-Atlantic Ridge over 10 million years and the interplay of volcanism and faulting. The gravity data were collected during two cruises, RC2511 (Detrick et al., 1984) and SEADMA I (Gente et al., 1995) and combined with available data sets from NOAA - National Centers for Environmental Information, and the 1991 SIGMA cruise (from the Banque de Bathymetrie et Geophysique Marine (SISMER) data bank, France). Processing of the data is described in Maia and Gente (1998). The MBA was computed assuming a constant crustal thickness model (Prince and Forsyth, 1988) using the method of Parker (1973). Crustal thickness was assumed to be 6 km. Densities of seawater, crust and mantle were considered constant (1030, 2700, and 3300 kg/m3, respectively). The thermal correction was computed using a passive flow model (Phipps Morgan and Forsyth, 1988) to obtain the RMBA. The data file is in GMT-compatible netCDF grid format. DOI: 10.26022/IEDA/331314

Description: Off-axis geophysical surveys provide a 26-m.y.-long record of axial tectonic and magmatic processes over a 660-km-long and melt poor portion of the ultraslow Southwest Indian Ridge. The data reveal a new type of seafloor (the smooth seafloor) that forms at minimal ridge melt supply, with little or no axial volcanism. The gravity data were primarily collected during Marion Dufresne cruise 135 in 2003 (https://campagnes.flotteoceanographique.fr/campagnes/3200080/). Details of the processing of the gravity data are provided in the Supplement Material section of Cannat et al. (2006). The residual mantle Bouguer anomaly (RMBA) was calculated from free-air ship gravity data by first subtracting the effect of topography of a constant crustal thickness (3.4 km; the mean seismic crustal thickness determined near 66°E (Muller et al., 1999)), constant density (2700 kg/m3) crust, and then the effect of upper mantle cooling with age (using magnetic anomaly picks). The thermal correction model assumes a simple square root of age mantle cooling law (Parsons and Sclater, 1977). The thermal model was cut off 25 km off-axis, and a constant temperature gradient used in the intervening axial region. The data files are in GMT-compatible netCDF grid format. The "mba" grid is the mantle Bouguer anomaly data and the "rmba" grid is the residual mantle Bouguer anomaly grid. DOI: 10.26022/IEDA/331313

Description: Shipboard free-air gravity data from R/V Ewing Cruises EW9208 and EW9606 in the Mid-Atlantic Ridge corridor at 24°-27°N were processed as described by Wang et al. (2015) to the obtain Residual Mantle Bouguer Anomaly (RMBA): The gravitational effects of seafloor topography and relief on the crust-mantle interface were subtracted from the free-air gravity anomaly to obtain mantle Bouguer anomaly (MBA), assuming a reference crustal thickness of 6 km and using the spectrum method of Parker (1973). Densities of water, crust, and mantle were assumed to be 1.03 10^3, 2.7 10^3, and 3.3 10^3 kg m^-3, respectively. RMBA was then calculated by removing the gravitational effect of lithospheric cooling from MBA, based on a 3-D mantle thermal model. The mantle thermal structure was calculated for a 100 km thick layer, using the 2-D age grid of Wang et al. (2015) and assuming simple 1-D plate cooling (Turcotte and Schubert, 2002; Wang et al., 2011). The parameters used in the calculation are the same as in Wang et al. (2011). This mantle thermal model was then converted to a 3-D mantle density structure, which was used to calculate gravitational effects. Note that, within a narrow axial region that contains ridge-axis offsets, this 1-D plate cooling model differs slightly from the 3-D passive mantle upwelling model used in Tucholke et al. (1997), in which lateral heat transfer across ridge offsets was considered. Thus, the calculated thermal structure and resultant gravity corrections for the 3-D passive upwelling model are smoother across ridge offsets than those predicted by the 1-D plate cooling model. However, differences between the two models are only a few mGal and are limited to a narrow zone proportional to the size of ridge offsets. The file presented here is in GMT-compatible netCDF grid format. Additional gravity and other shipboard data in this region are available at https://doi.org/10.26025/z2z7-kd89.

Description: Gravity data collected during KN182-03 were combined with the gravity data from Fujiwara et al. (2003) and processed as described by Smith et al (2008). The free-air gravity data were reduced to obtain the mantle Bouguer and the residual mantle Bouguer anomalies (MBA and RMBA, respectively) following standard procedures (Kuo and Forsyth, 1988; Prince and Forsyth, 1988). The effects of the water-crust and crust-mantle interfaces were subtracted from the free-air gravity anomaly along tracks to obtain MBA using the method of Parker (1973), and assuming a crustal thickness of 5 km. Densities of water, crust, and mantle were assumed to be 1030, 2750, and 3300 kg/m3, respectively (Escartin and Cannat, 1999). The gravity thermal effect due to spreading was calculated using a passive upwelling model and the ridge geometry (Phipps Morgan and Forsyth, 1988). The calculated thermal effect was removed from the MBA along tracks to obtain the RMBA, which was then gridded. The data were gridded for 13°-15°N and the grid covers the Mid-Atlantic Ridge between the Fifteen-Twenty and Marathon fracture zones. The file presented here is in GMT-compatible netCDF grid format.

Description: The MARGIN site is at a buried basement high (likely a buried seamount) offshore Oregon, ~25 km seaward of the Cascadia subduction zone deformation front. The buried basement high rises ~1300 m above the surrounding basaltic basement. The MARGIN basement high was first identified on the north-south-trending MARGIN transect, collected as part of the Juan de Fuca Ridge-to-Trench project; that seismic transect crossed the flank of the MARGIN basement high. Subsequently, the east-west-trending Line PD11 collected as part of the MGL2104 CASIE21 project conducted in 2021 crossed a higher and more substantial portion of the MARGIN basement high. In 2022, in-situ measurements of thermal gradient were collected crossing and around the MARGIN basement high using a 3.5-m violin-style heat flow probe. This multi-penetration heat flow probe was loaned from the U.S. Marine Heat Flow Capability. The thermistor string houses 11 thermistors. The in-situ thermal gradient is combined with an assumed thermal conductivity versus depth trend to determine the heat flow. The data was processed using SlugHeat (https://marine-heatflow.ceoas.oregonstate.edu/software/). The data file is in ASCII tab-separated format, with column headers. Funding was provided by National Science Foundation awards OCE19-24331, OCE20-34872, and OCE20-34896. DOI: 10.26022/IEDA/331310

Description: The first high-resolution seismic survey, MERC I, in the area offshore Eilat in the northern Gulf of Aqaba was conducted from 29 October to 16 November 2006 and included the acquisition of 261 seismic lines with a total length of 426 km. The survey was carried out in two phases: deep survey (water depths of 100–700 m) onboard the R/V Etziona and a shallow phase (water depths of less than 100 m) onboard a fishing vessel called Danny-Boy. The high-resolution geophysical survey used a GeoResources GeoSparker200 seismic source generated by electrical spark at energies of 300–1000 J and seismic frequencies of 200–3000 Hz. During the deep survey, the system used two hydrophone arrays (i.e. dual-channel), one towed parallel to the sparker, and the other offset about 50m attempting to receive more seismic energy across steep slopes. In the shallow survey only one hydrophone array (i.e. single-channel) was towed parallel to the sparker. The seismic acquisition parameters are described in the associated documents. Funding was provided through the U.S. Agency for International Development Middle East Regional Cooperation program (MERC) under contracts TA-MOU-05-M25-004 and TA-MOU-08-M29-036.

Description: Mantle Bouguer anomaly (MBA) was calculated by removing the gravitational effects of the water-crust and crust-mantle interfaces from the Free-air anomaly (FAA), assuming water, crust, and mantle densities of 1.03 × 10^3, 2.7 × 10^3, and 3.3 × 10^3 kg m^-3, respectively, and using a 6-km thick reference crust. Residual Mantle Bouguer anomaly (RMBA) was calculated by subtracting age-dependent thermal model from the MBA. The end-member model of the crustal thickness model here was calculated by the downward continuation of the RMBA to a depth of 10 km by assuming that the RMBA is controlled only by variations in crustal thickness. Free-air anomaly (FAA) was generated by combining the shipboard FAA data from cruise SR1806 with global satellite FAA data from Sandwell et al. (2014). The lithosphere cooling effect (i.e., thermal model) is estimated by assuming a 1-D half space plate cooling model. The data files are in GMT-compatible netCDF grid format. All data were gridded at 1-arc-second node spacing. The gravity calculation region is from 105°W to 95°W and 1°S to 5°N, but we suggest using data within 104°W to 96°W and 0 to 4°N to avoid boundary effects.

Description: Pythia's Oasis is a methane seep site 60 nautical miles offshore the coast of Oregon. This site is different from other seep sites. It hosts a discrete orifice that has continually vented low-salinity, hydrocarbon-bearing fluids since 2015 and was still active as of August of 2022. The site was discovered in 2015 during a Regional Cabled Array (RCA) Operations and Maintenance Cruise using hull-mounted sonar on R/V Thompson to detect methane bubble plumes in the water column. In 2019, in-situ measurements of thermal gradient and thermal conductivity were collected using the OSU 3.5-m violin-style heat flow probe. The thermistor string houses 11 thermistors and measures both the in-situ thermal gradient and thermal conductivity that are combined to determine the heat flow. On most measurements the probe position was determined with ultra-short baseline telemetry (USBL). The data was processed using SlugHeat (https://marine-heatflow.ceoas.oregonstate.edu/software/). The data file is in Excel spreadsheet format, with column headers. Funding was provided by National Science Foundation award OCE19-02446. DOI: 10.26022/IEDA/331300

Position and attitude data were provided by a Kearfott SeaDevil Inertial Navigation System (INS) integrated with a 1200 kHz Teledyne RD Instruments Doppler velocity log (DVL) and a Paroscientific pressure sensor. The LASS sensor package was mounted in an articulating frame within an ROV tool sled that rotates from pointing the sensors vertically down to horizontally forward, allowing surveys of flat to vertical seafloor. The articulation is automated by closing a control loop around the difference between the forward and backward beams of the DVL. Funding was provided by a grant from the David and Lucile Packard Foundation to MBARI.

Description: This data set consists of a 3-D tomographic model of the P-wave seismic velocity structure of the upper 4 km of the crust of Santorini caldera and the surrounding region. The model was derived from active-source data acquired during the PROTEUS 3-D seismic tomography experiment conducted during Langseth cruise MGL1521 in 2015 (chief scientists Emilie Hooft, Doug Toomey, & Paraskevi Nomikou). The model and results are described in Heath et al. (2019). The data was collected using a dense amphibious array of >14,300 marine sound sources from a 6,600 cubic inch 36-component air gun array towed at 12-m depth that were recorded on 156 short-period marine and land seismometers, covering an area 120 km by 45 km. Average shot spacing was ~150 m along ENE-WSW oriented shot lines spaced at 1–2-km intervals and included shot-receiver offsets up to ~115 km. A three-dimensional, iterative tomographic technique (Toomey et al., 1994) was used to invert over 200,000 Pg refraction arrival times to constrain isotropic slowness within the upper crust. The data file is in SEG-Y format with UTM coordinates (zone 35N) and with P-wave velocity on a grid that is spaced 200 m horizontally and 50 m vertically. This model is NOT masked in regions of poor ray coverage and poor resolution. This data set was generated as part of the project called Collaborative research: Crustal magma plumbing of the Santorini volcanic system. Funding was provided by NSF grants OCE14-59794.

Description: Pythia's Oasis is a methane seep site 60 nautical miles off the coast of Oregon. This site is different from other seep sites. It hosts a discrete orifice that has continually vented low-salinity, hydrocarbon-bearing fluids since 2015 and is still active as of August of 2022. The site was discovered in 2015 during a Regional Cabled Array (RCA) Operations and Maintenance Cruise using hull-mounted sonar on R/V Thompson to detect methane bubble plumes in the water column. In 2019, near-bottom swath bathymetry data were collected using a Reson 7125 multibeam sonar system mounted on AUV Sentry during Pythia's Oasis Cruise AT42-17. Six AUV Sentry sonar surveys were conducted. The data were processed and two bathymetric data sets were produced: One is a 2,600 meter by 2,400 meter composite of data from all AUV dives gridded at 1-meter resolution and the other is a 1,500 meter by 800 meter data set from a low-altitude dive gridded at 0.25 meters. The images presented here are in GeoTIFF raster image format and the resolution is given in the file name. Funding was provided by National Science Foundation award OCE16-58201.

Description: This bathymetry synthesis covers the Santorini-Christiana-Amorgos backarc region of the Hellenic subduction zone. The data were collected during the 2015 PROTEUS cruise on R/V Langseth that had the goal of imaging the magma plume structure of the Santorini volcanic system. The PROTEUS experiment deployed a dense array of ocean-bottom and land seismometers that recorded the marine sound source from the ship. The multibeam synthesis was generated by merging hull-mounted EM122 multibeam data collected during the PROTEUS cruise (MGL1521 cruise DOI: 10.7284/906516) with pre-existing data from near the coast and within the caldera of Santorini. Those data sets are from Nomikou et al., 2012 (https://doi.org/10.1016/j.gloplacha.2012.01.001) and Nomikou et al., 2013 (https://doi.org/10.1016/j.tecto.2012.10.001). The file presented here is in GMT-compatible netCDF grid format, with a horizontal resolution of 115m. The raw PROTEUS multibeam data is available at: https://www.marine-geo.org/tools/search/entry.php?id=MGL1521. Funding was provided by National Science Foundation award OCE14-59794.

Description: Near-bottom magnetic data was collected at the East Pacific Rise, from 9°50'N, during a total of 20 AUV Sentry dives conducted from R/V Atlantis and R/V Roger Revelle during 2018 Atlantis cruise AT42-06 (three dives); 2019 Atlantis cruise AT42-21 (ten dives); and, 2021 Revelle cruise RR2102 (seven dives). Track lines were spaced 170 m apart, with Sentry about 70 m above bottom, collecting magnetic data using three Applied Physics Systems Model 1540 triaxial fluxgate magnetometers mounted on AUV Sentry. Sentry navigation was obtained using a 300 kHz Teledyne Doppler velocity log (DVL) and a Sonardyne AvTrak2 ultra-short baseline (USBL) acoustic positioning system, combined with an iXblue Phins inertial navigation system (INS), and a Paroscientific 8B7000-I Digiquartz depth sensor. The three-component magnetic data is in MATLAB binary format, one file per Sentry dive, with z being the observed magnetic field. The MATLAB data structure includes X,Y,Z component fluxgate data for each of three sensors where X,Y,Z are in sensor coordinates. The data structure also contains time, latitude, longitude, depth, altitude, roll, pitch, heading, and temperature. The Sentry dive number is given in the file name.

Sentry navigation was obtained using a 300 kHz Teledyne Doppler velocity log (DVL) and a Sonardyne AvTrak2 ultra-short baseline (USBL) acoustic positioning system, combined with an iXblue Phins inertial navigation system (INS), and a Paroscientific 8B7000-I Digiquartz depth sensor. The magnetic data are in ASCII text format, with one file each for top, port, and starboard magnetometers. Each ASCII file contains 11 columns, as follows: lon (degrees), lat (degrees), time (unix time, seconds), depth (m), altitude (m), roll (degrees), pitch (degrees), heading (degrees), X, Y, Z components of magnetic field strength (in oersted, i.e. x10^5 nT). Note that the magnetic data are X,Y,Z in sensor coordinates. The Sentry dive number and magnetometer mount point location is given in the file name. The three ASCII files for each dive correspond to one combined MATLAB file in an associated data set. Funding was provided by National Science Foundation awards OCE-1834797, OCE-1949485, OCE-1948936, and OCE-1949938. DOI: 10.26022/IEDA/331247

Track lines were spaced 170 m apart, with Sentry about 70 m above bottom, collecting magnetic data using three Applied Physics Systems Model 1520 triaxial fluxgate magnetometers mounted on AUV Sentry. Sentry navigation was obtained using a 300 kHz Teledyne Doppler velocity log (DVL) and a Sonardyne AvTrak2 ultra-short baseline (USBL) acoustic positioning system, combined with an iXblue Phins inertial navigation system (INS), and a Paroscientific 8B7000-I Digiquartz depth sensor. The magnetic data was gridded at 10 m × 10 m node resolution. The grid files are in GMT-compatible netCDF format, in un-projected geographic coordinates. Three grid files are presented here, as follows. File 2400mergeT.grd is the total magnetic field anomaly, upward continued to 2400 m below sea-level. File const20anni.grd is the total field crustal magnetization, calculated using constant layer 2A thickness of 500 m. File var20anni.grd is the total field crustal magnetization, calculated using variable layer 2A thickness, constrained from seismic reflection images (Harding et al., 1993; Marjanovic et al., 2018).

Description: This data set contains interpreted polygons describing different sedimentary energy environments of the Long Island Sound mapping project Phase II. This data set is the result of manual interpretation of detailed bathymetry data and resulting seafloor morphology, backscatter data, sediment core analysis results, and interpretation of sub-bottom data. It distinguishes high, low, and moderate energy environments, which can be caused by current and wave action. The outline of polygons was based on manual interpretation mostly following morphological and backscatter boundaries. Interpretation was cross-checked with sediment grab and core information. Polygon outlines are based on morphology and backscatter data that have 1 m pixel resolution, but interpretation could be several pixels (~ +/-10 m) in each direction, since the exact boundary is not always clear. Small pockets of different environments might not have been distinguished. The data is presented here as an ESRI shapefile in UTM-18 N projection. Funding was provided by the Long Island Sound Mapping Fund administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).

Description: This data set contains interpreted polygons describing different sediment texture distribution of the Long Island Sound mapping project Phase II area. This data set is the result of manual interpretation based on surface grab grain size analysis combined with detailed bathymetry and backscatter data. The outline of polygons was based on manual interpretation using grain size data from sediment grab analysis and mostly following backscatter boundaries. There were smaller areas with different backscatter signal, for which there were no grab samples for ground verification. Changes in the backscatter values do not always correspond to the observed grain size results. In these cases, grain size results from grabs were used as the main guidance. Polygon outlines are based on backscatter data that have 1 m pixel resolution, but interpretation could be several pixels (~ +/-10 m) in each direction, since the exact boundary is not always clear. Small pockets of different environments might not have been distinguished. The data is presented here as an ESRI shapefile in UTM-18 N projection.

Description: Sediment grab samples were taken in summer of 2017 and 2018 using a modified van Veen grab sampler. A sub-sample of the top two centimeters was taken for further lab analysis. Dried and homogenized splits of the samples were analyzed for chemical composition using an Innov-X Alpha series 4000 XRF (Innov-X Systems, Woburn, MA). The results of the measurements are presented as ppm. The XRF analytical protocol included the following elements: P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn As, Se, Br, Rb, Sr, Zr, Mo, Ag, Cd, Sn, Sb, I, Ba, Hg, Pb, Bi, Th, and U. However, only Cl, K, Ca, Ti, Cr, Mn, Fe, Co, Cu, Zn, As, Br, Rb, Sr, Zr and Pb were consistently present at levels above background detection in surficial sediments collected in the LIS Phase II area. ArcGIS Pro empirical kriging has been used to interpolate values for selected elements onto a 50 m raster. The interpolated raster has been clipped to fit the extent of the phase 2 survey area. The final raster data files are in GeoTIFF grid format with UTM-18 N projection.Funding was provided by the Long Island Sound Mapping Fund administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).

Description: Sediment grab samples were taken in summer of 2017 and 2018 using a modified van Veen grab sampler. A sub-sample of the top two centimeters was stored in a jar. Dried and homogenized splits of the samples were sent to the Cornell Isotope Laboratory (COIL) to be analyzed for carbon and nitrogen concentrations as well as stable isotopic compositions. Total carbon (TC), total nitrogen (TN), and δ15N were determined on an aliquot of untreated, dried homogenized sediments. In order to accurately determine total organic carbon (TOC) and δ13C, removal of carbonate is necessary. This was achieved through sequential treatments of the sediments with dilute hydrochloric acid until no bubbling was observed. The acidified sediments were then rinsed in deionized water and re-dried. In the Cornell Lab the samples were analyzed using a NC2500 elemental analyzer interfaced with a Thermo Delta V isotope ratio mass spectrometer (IRMS). ArcGIS Pro empirical kriging has been used to interpolate values for organic carbon, total carbon, nitrogen, d13C and d15N isotope content onto a 50 m raster. The interpolated raster has been clipped to fit the extent of the phase 2 survey area.

Description: Sediment grab samples were taken in summer of 2017 and 2018 using a modified van Veen grab sampler. A sub-sample of the top two centimeters was taken and stored in a jar. Dried sub-samples samples were analyzed for grain size. First, the samples were treated with hydroperoxide to remove organic components. Then, the sample was passed through a series of standard sieves representing Phi sizes with the smallest being 64 µm. The content of each sieve was dried and weighed. If there was sufficient fine material (< 64 µm), this fine fraction was further analyzed using a Sedigraph system. The results of sieving and sedigraph analysis were combined and the percentages for gravel, sand, silt and clay were determined following the Wentworth scale. In addition, other statistics including mean, median, skewness and standard deviation were calculated using the USGS GSSTAT program. The results of the LDEO/Queens College grain size analysis were combined with data collected by the LISMARC group and analyzed by USGS. ArcGIS Pro empirical kriging was used to interpolate values for gravel, sand, silt, clay, and mud percentages as well as for mean grain size onto a 50 m raster. The interpolated raster was clipped to fit the extent of the phase 2 survey area. The final raster data files are in GeoTIFF grid format with UTM-18 N projection.

Description: Seafloor sidescan data provides important information on water depth and on the character of features on the seafloor to improve our understanding of benthic habitat. Sidescan and multibeam sonar data was collected in 2017-2018 during field surveys by SoMAS, Stony Brook University, in eastern Long Island Sound as part of the Phase 2 of the Long Island Sound Cable Fund Benthic Habitat Mapping Project. The sidescan files in this data set are in GeoTIFF image format and cover 10 of the 27 Survey Blocks assigned to SoMAS. The values of sidescan acoustic backscatter reported in these images depends somewhat on the equipment used and the computer processing that is done in creating the backscatter images. Acoustic backscatter data recorded depends on the azimuth of the sonar track so the final images tried to keep acoustic data collected in a similar orientation. The sidescan sonar data was collected with a pole-mounted system and there was some small across-track amplitude variation due to the instrument roll and there are some residual along-track amplitude variations related to the sonar beam pattern. Although no quantitative analysis was done, the sidescan backscatter data reported during this project is qualitatively similar to that reported by NOAA in NCEI Dataset 0167531 when the image DN values are appropriately stretched. The data is not to be used for navigation. The sidescan field surveys were performed in December 2017 to March 2018 (file names DM). The data was collected on the SoMAS Research Vessel Donald W Pritchard using a pole-mounted EdgeTech 272-TD system which was operated at 100 kHz. All field programs used an Applanix motion sensor system for vessel motion and heading, GPS positions corrected using data from the ACORN RTN (UConn) system, vessel elevations determined using GPS RTN elevations supplemented by scaled and offset land-based water-level measurements, and sound velocity profiles collected using an AML BASEX probe. The sidescan data was recorded in xtf format and processed using programs in the SwathEd program suite developed at the University of New Brunswick (UNB) with modifications done at Stony Brook University. The sonar position, altitude and orientation (heading, roll and pitch) were merged with the sonar data using values recorded by the multimbeam system operating at the same time. The xtf files where re-written with updated sonar navigation, altitude, heading, roll and pitch and those files have been archived. A slant-range correction was made assuming a flat sea floor and the sonar values were plotted on a 1 m grid but only the data closest to a ship track was plotted. The ship tracks used in the mosaic were selected to have consistent orientations and to avoid crossing lines. A correction was applied to the sidescan sonar data based on fish height and slant range to correct signal levels for sonar beam pattern, attenuation and angle-of-incidence but some along-track signal anomalies exist in the map grids. The final maps were made using the corrected signal levels. No correction was made for instrument roll and there is some striping in the sonar mosaics because of the sonar roll. The 8-bit sonar mosaics were imported to ArcMap as tif files and exported as georeferenced GeoTIFFs. Horizontal positions are accurate to about 1 m. The data files show the conditions at the time of the survey in 2017-2018. The full suite of SoMAS mapping comprises four components: multibeam bathymetry (26 maps), bathymetry hillshade (26 maps), multibeam backscatter (26 maps), and sidescan sonar backscatter (9 maps), for a total of 87 maps. The multibeam bathymetry and backscatter data were integrated by NOAA into project-wide maps that can be found at NCEI (Dataset 0167531 version 2.2, https://doi.org/10.25921/tgp1-w632). Funding for this study was provided by the Long Island Sound Seafloor Mapping Fund administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).

Description: Seafloor bathymetry and acoustic backscatter data provides important information on water depth and on the character of features on the seafloor to improve our understanding of benthic habitat. Multibeam sonar data was collected in 2017-2018 during field surveys by SoMAS, Stony Brook University, in eastern Long Island Sound as part of the Phase 2 of the Long Island Sound Cable Fund Benthic Habitat Mapping Project. The acoustic backscatter files in this data set are in GeoTIFF image format and cover the 27 Survey Blocks assigned to SoMAS plus a site in deeper water (Barchans). The backscatter images were created using the program QPS FMGT using multibeam track lines that had been edited and processed by CARIS HIPS and SIPS. The program corrects the sonar data to remove cross-track variations in signal levels. Two different multibeam systems were used to collect the data reported for this study and the data values from the two systems were compared in areas where data sets overlapped. The results from the EM3000D survey were offset and scaled so that the backscatter distributions in the overlap areas were similar. 8-bit multibeam backscatter grids were exported as GeoTIFF images. For all the images reported, higher backscatter values are shown in a lighter color and lower backscatter are shown in a darker color. The 2017-2018 SoMAS surveys have few gaps except for 13_JJ (a compilation of transit tracks that overlap the grid 13_DM) and Barchans (lines that image barchan dunes that are migrating across the seafloor). The data is not to be used for navigation. The field surveys were performed in December 2017 to March 2018 (file names DM) and June-July 2018 (file names JJ). The data was collected on the SoMAS Research Vessel Donald W Pritchard using an EM3000D echo-sounder for the surveys from December, 2017 through March, 2018, and using an EM2040cD (dual-head) echo-sounderfor data collected in June and July, 2018. All field programs used an Applanix motion sensor system for vessel motion and heading, GPS positions corrected using data from the ACORN RTN (UConn) system, vessel elevations determined using GPS RTN elevations supplemented by scaled and offset land-based water-level measurements, and sound velocity profiles collected using an AML BASEX probe. Bathymetry data was processed using CARIS HIPS and SIPS (version 10.4). Data points were edited to remove spurious bed elevations and sound-velocity refraction corrections were applied. Data values were gridded at 1 m horizontal resolution using the Swath Angle gridding algorithm into a series of 26 base maps (resolution is 2 m for the 2018 Barchans file). The 32-bit GeoTIFF gridded base maps are projected in NAD_1983_2011_UTM_Zone_18N and seafloor elevations are reported in meters relative to NAVD-88. Vertical elevations are accurate to about 0.1 to 0.2 m. Elevations may be less accurate at the outer edges of the swath where refraction artifacts can occur. Horizontal positions are accurate to about 1 m. The data files show the conditions at the time of the survey in 2017-2018.

Description: Processed results from of chemical composition of the sediment core as measured with the Lamont ITRAX Core Scanner (Cox Analytical Systems, Mölndal, Sweden). For XRF measurements, an X−ray tube equipped with a molybdenum anode was operated at a voltage of 30kV and a current of 55mA. Each measurement was made for 30s integrated over a depth interval of 0.5cm by 17mm wide. After scanning was complete, any spectra flagged as invalid were removed and all remaining spectra were summed into a single spectrum. A full spectrum fundamental parameter peak fitting program, provided by the manufacturer, was used to calculate individual elemental abundances in terms of element rates (i.e., cps/mA). Variables in the fundamental parameter algorithm were adjusted to minimize the difference between the measured spectra and the model fit. Once the fitting routine was complete, the optimized parameters were used to calculate down-core elemental rates. The analytical uncertainty of the element signals is estimated based on the dead time corrected total counts for each element. Prior to calibration, elemental rates were first normalized to the coherent scattering peak signal to account for matrix variability and then standardized for each core/each element by subtracting the average element rate and dividing by the standard deviation of the element rate. The data are presented as Excel spreadsheet with one worksheet per core. DOI: 10.26022/IEDA/331159

Description: Physical Property data of the sediment cores collected with a gravity corer as part of the Long Island Sound mapping project Phase II. Physical properties were measured at 1 mm intervals using a GEOTEK Multi-Sensor Core Logger. Properties measured included density, porosity and magnetic susceptibility. In order to precisely co-register information from the different sensors, each core was run in a custom sample holder equipped with density, height, and distance markers, as well as wet bulk density calibration section. In order to achieve high-resolution density measurements, the window on the NaI detector, used to measure gamma ray attenuation, was modified to a 1 mm x 20 mm slit using a custom-made lead insert. We further modified the system by reconfiguring the laser displacement sensors to make precise, non-contact core thickness deviation measurements, which are required to estimate wet bulk density from the gamma attenuation signal. Magnetic susceptibility was measured using a Bartington MS2E sensor with a probe diameter of 25mm. The Excel spreadsheet has one worksheet per core. DOI: 10.26022/IEDA/331158

Description: Images of the sediment cores collected as part of the Long Island Sound mapping project Phase II. The images were taken of on split cores at the Lamont core repository using the Itrax imaging system and converted to jpeg. The images have been cropped to fit closely to the core extent. Sediment cores provide information on changes in the sediment environments over time including periods of deposition or erosion, as well as changes in chemical composition with time. Detailed images of the sediment cores provide information on layering and visual changes and disturbances along the core. This information is guiding the sediment environment interpretation.

Description: Near-bottom sidescan data was collected with an Edgetech 2205 sidescan system on AUV Sentry dives 597-606 during PLUME RAIDERS cruise RR2106 in 2021 at 16.5°-18° S on the Southern East Pacific Rise (investigators Chris German, Joseph Resing, Scott White). Sidescan at 240Khz was collected during 5 of the earlier Sentry dives (dives 597, 598, 599, 601, 602) as the low-frequency channel. A regular interference pattern is present in all 240Khz sidescan mosaics collected during this cruise. This led to the use of the 120 Khz low-frequency sonar instead for Sentry dives 600 and 603-606. The data files are in GeoTIFF format and were processed using SonarWiz version 7 to merge with corrected AUV navigational records, trim the swath edges, bottom-track, and equalize gain across-track. The files were generated as part of the projects called Finding hydrothermal chimneys along the southern East Pacific Rise with machine learning approaches to AUV-based sonar data; and, Are Low-Temperature Hydrothermal Vents an Important but Overlooked Source of Stabilized Dissolved Iron to the Ocean?

Description: The data set contains velocity models derived from first arrival seismic tomography methods applied to a seismic survey collected for reflection seismic purposes. The original data set was collected as a reflection seismic survey and therefore the data set did not contain forward and reverse shots. Additionally, unlike most seismic tomography surveys, the seismic source and the hydrophones or receivers remained at a constant distance (e.g. the source was always the same distance from channel 1 or channel 144). The source and streamer (array of receivers) were towed behind the vessel and the source or air guns were fired every 6.25 meters. Shot gathers in SEG-Y format were imported into the Geogiga DW TOMO software in 10 shot increments with spacings of ~62.5 meters. This provided a spatially-dense data set for every line, with overlapping ray paths. This software uses ray tracing or the shortest path method in the forward modeling process (Moser, 1991). The forward model or initial velocity model is a sub-surface velocity model defined by the user. The intent of the tomography-derived velocity models was to independently confirm results from seismic reflection data, as well as provide information on the depth to basement in areas where reflection data failed to image the sub-surface stratigraphy. Therefore, a priori data from the reflection data set was limited in the tomography inversion process. The initial model contained a surface velocity of 1350 m/s and increased to 1600 m/s over a depth of 15 meters. Below 15 meters the model increased by 390 m/s every 1 meter to reach a velocity of 5500 meters at 25 meters depth. The same forward model was used for every line, and each line was subjected to 9 iterations with a maximum disturbance of 75%. The inversion process used an algorithm adapted from Toomey et al. (1994) which accounts for previous knowledge such as the prior iteration, smoothing parameters, and travel time uncertainties which are established by the user. Following careful parameter testing, the smoothing parameters chosen for use in the algorithm were 3.75 m for the vertical smoothing, 15.5 m for the horizontal smoothing, and a picking uncertainty of 1 ms. The velocity models are in ASCII text file format and each text file is named after the corresponding seismic reflection profile. In the text files, the first column is depth in meters, the second column is velocity in meters/second, the third column is UTM northing and the fourth is UTM easting (both in meters, UTM zone 18N). A total of 13 lines were processed using the first arrival tomography technique. It should be noted that data coverage or ray path density is much lower for the first few hundred meters of each line. Therefore, the beginning and end of each velocity model should be examined carefully and likely removed from the survey. The data files were generated as part of a project called P2C2: A High Resolution Paleoclimate Archive of Termination I in Oneida Lake and Glacial Lake Iroquois Sediments. Funding was provided through NSF grant EAR18-04460 to Syracuse University. DOI: 10.26022/IEDA/331043

Description: In this active-source experiment at the Santorini-Amorgos Tectonic Zone, multi-channel seismic reflection data was collected during Poseidon cruise POS338 in 2006 (chief scientist Prof. Dr. Christian Hübscher, University of Hamburg). The airgun seismic source was a single G.I. gun that was used in true G.I. mode (Injector volume: 45 cubic inches; Generator volume: 105 cubic inches) producing a signal of 100 Hz main frequency. The seismic shot data was recorded with a 24-channel streamer of 600 m length (25 m channel spacing), and stored in SEG-Y format. The processed seismic data files presented here are in SEG-Y format. Processing of these data comprised trace-editing, simple frequency filtering (10-500 Hz), suppression of a receiver-ghost signal by predictive deconvolution, surface-related multiple elimination as well as spherical divergence correction, pre-stack time migration followed by top-muting and white-noise removal. These data have a main frequency of 60 Hz indicating a vertical resolution of approx. 8-15 m.This processed seismic data set is interpreted in Preine et al., Tectonics, 2022. The study was funded with German Research Foundation DFG grant HU690/25-1. DOI: 10.26022/IEDA/331028

Description: This microseismicity catalog is derived from data retrieved from ocean-bottom seismometers deployed in 2008 as part of the Quebrada-Discovery-Gofar (QDG) Transform Fault Experiment. The data file is in ASCII text format. The first row is a column header that describes the content of the catalog: Earthquake origin time, latitude, longitude, depth, and local magnitude. Not all earthquakes have a local magnitude estimate because of the selection criteria. Details of the earthquake location methodology and location interpretations can be found in the paper "Seismicity, fault architecture, and slip mode of the westernmost Gofar transform fault" by Gong and Fan, 2022, JGR. The data set was generated as part of the projects called Capturing 4D Variations in Stress, Slip, and Fault-Zone Material Properties: The 2019-2021 Gofar Transform Fault Earthquake Prediction Experiment; and, CAREER: Using seismic sources to probe megathrust fault conditions. The project was funded by NSF awards OCE-1833279 and EAR-2143413. DOI: 10.26022/IEDA/331024

Description: This is the prestack depth migrated seismic reflection data volume that was produced from multi-channel seismic lines acquired during the Langseth cruise MGL1801 as part of the NZ3D Hikurangi margin project in 2018. This SEG-Y file is a 3D migration produced by CGG in Singapore using a Kirchhoff 3D prestack depth migration algorithm. This volume includes advanced signal processing to remove multiples, source and receiver ghost, and other artifacts (see associated processing report for details). The volume was migrated after signal processing using seismic velocities derived from streamer data and 97 OBS provided by JAMSTEC. The velocity model was constructed as a 3D anisotropic (TTI) model using 3D full waveform and tomographic inversion (details are provided in the processing report, and the model is available here as a linked data set). The accompanying information document describes the 3D grid parameters including bin grid origin and orientation for workstation loading, the Data Parameters, the SEG-Y trace header, and the processing sequence. The data set was generated as part of the project called "A community 3-D seismic investigation of fault property controls on slow slip along the Hikurangi megathrust".

Description: This dataset was acquired with a pressure-temperature logging system deployed in the original CORK installed in July 1997 in Hole 395A in North Pond on the western flank of the Mid-Atlantic Ridge during ODP Leg 174B (Becker et al., 2001). The system included Paroscientific model 8B7000-110 borehole and seafloor pressure gauges and a ten-thermistor sensor cable extending down to nearly 600 m below seafloor. Data were accessed during dives of the manned research submersibles Nautile in 1998 and Alvin in 2001, and when the system was recovered during IODP Expedition 336 in 2011. The data file is in tab-delimited Text File (ASCII) format recorded every hour. Each line includes date/time, borehole pressure, seafloor pressure, temperatures in °C of 8 valid downhole thermistor readings and bottom-water temperature from a matching thermistor in the data logger. Temperatures were obtained from raw binary data by applying a logger count to resistance calibration and individual thermistor resistance to temperature calibrations. Support for acquisition of the sensor string and 1998/2001 submersible dives was provided by NSF award OCE-9530426 (K. Becker, PI) Instrumented borehole seals for 1996 ODP drilling on the Juan de Fuca Ridge (modified after one year to include the 395A CORK). Long-term pressure and temperature data from Hole 395A are presented by Becker et al. (2022). DOI: 10.26022/IEDA/330948

Description: This data set consists of thermal gradients and thermal conductivity to compute the heat flow in Pescadero Basin, Gulf of California. The data have been processed to convert from resistance to temperature using calibrations for each thermistor. Heat flow was estimated by combining the thermal gradient and thermal conductivity using the Bullard method. The data set was collected using a custom 1-m long ROV heat flow probe from Andrew Fisher, UC Santa Cruz. The heat flow probe was deployed on ROV SuBastian dives S0463-S0481 during Falkor cruise FK210922, operated by Schmidt Ocean Institute. Each deployment of the heat flow probe lasted approximately 15 minutes. The data file is in tab-separated ASCII text format with column headers and units. Funding was provided through awards from Schmidt Ocean Institute and internal funding from MBARI, CICESE, UABC, and CALTECH. DOI: 10.26022/IEDA/330947

Description: This data set presents images of each seismic velocity model and corresponding ray coverage. The top panels show the Derivate Weight Sum (DWS) of each model, which is a measure of ray density in the model grid space. Likewise, the density of bounce points on each reflecting boundary is shown by the relative size of black circles. DWS can be used to assess areas of poor ray coverage and hence use caution when interpreting velocities or layer boundary depths in these domains. Here, the base10 logarithm of DWS for each model is taken and the corresponding colormap and size of circles along boundaries are normalized to span the minimum and maximum of these values. This normalization is done for each individual model – thus, the plots show relative areas of good and bad ray coverage within a single model but should not be used to quantitatively compare ray density from model to model. Velocity models are plotted with 1 km/s contours. These image files are in PNG format. This data set was generated as part of the projects called Seismic study of mantle deformation and melt extraction during continental breakup in the ENAM primary site; and, Final stages of breakup and early spreading history of the Eastern North America passive margin from multichannel seismic data. Funding was providing through NSF awards OCE15-51717 and OCE15-51807. DOI: 10.26022/IEDA/330944

Description: This data set presents the velocity model geometry, and the data files describe the spatial link between geographic coordinates and cartesian coordinates of the velocity models. The models were constrained by traveltime tomography of active-source Ocean Bottom Seismometers data along three profiles from the Eastern North American Margin Community Seismic Experiment (ENAM CSE). P-wave velocity models for Line 1, Line 2, and Line 3 are included as well as a S-wave velocity model for Line 3. Collectively, these tomographic velocity images reveal subsurface properties and information on the ancient rifting event between eastern North America and west Africa during the breakup of Pangea and formation of the Central Atlantic ocean, but may also be relevant for other studies such as modern processes along the margin. The data files are in ASCII format. Columns are: Longitude (decimal degrees), Latitude (decimal degrees), X-coordinate (km), Water depth (km). This data set was generated as part of the projects called Seismic study of mantle deformation and melt extraction during continental breakup in the ENAM primary site; and, Final stages of breakup and early spreading history of the Eastern North America passive margin from multichannel seismic data.

Description: This data set presents the velocity model interfaces. The velocity models were constrained by traveltime tomography of active-source Ocean Bottom Seismometers data along three profiles from the Eastern North American Margin Community Seismic Experiment (ENAM CSE). P-wave velocity models for Line 1, Line 2, and Line 3 are included as well as a S-wave velocity model for Line 3. Collectively, these tomographic velocity images reveal subsurface properties and information on the ancient rifting event between eastern North America and west Africa during the breakup of Pangea and formation of the Central Atlantic ocean, but may also be relevant for other studies such as modern processes along the margin. These data files are in ASCII format and describe the coordinates of layers within the velocity models. Each model consists of four layers (top to bottom): siliciclastic sediments, carbonaceous sediments, crust, mantle. Layer coordinates are exported every 180 meters in the X direction. Columns are: Layer ID, X-coordinate (km), Z-coordinate (km). Layer ID: 1 = seafloor, 2 = top of carbonates, 3 = top of basement, 4 = Moho.

Collectively, these tomographic velocity images reveal subsurface properties and information on the ancient rifting event between eastern North America and west Africa during the breakup of Pangea and formation of the Central Atlantic ocean, but may also be relevant for other studies such as modern processes along the margin. The data files are in ASCII format and the velocity models are exported every 180 meters in the horizontal X direction, and every 90 meters in the vertical Z direction. Columns are: X-coordinate (km), Z-coordinate (km), Vp (km/s). The X-coordinate of Line 1 and Lines 2 models is zero at the coastline. Model Z-coordinates are positive and increasing with depth. Line 1 and Line 2 models start at one kilometer above sea level (-1.0) due to the landward extension of the profiles; however, the onshore domain is not shown or archived here due to poor ray coverage. For the line 3 velocity model, the data file columns are: X-coordinate (km), Z-coordinate (km), Vs (km/s). This velocity model was produced by traveltime inversion of shear-waves that were converted at the seafloor. Note that these phases traveled as P-waves throughout the water column, hence there is a corresponding P-wave velocity of ~1.5 km/s above the seafloor.

Description: CHIRP sub-bottom data were collected in the Sacramento-San Joaquin Delta, CA in October 2017. The purpose of these data was to image any deformation features in the shallow sediments associated with faults in the region and identify locations for sediment sampling. These sub-bottom profile processed images are in JPEG format and are derived from SEG-Y files that were collected with an Edgetech 3200-XS SB-512i instrument in a floating frame towed by a pontoon boat with the bottom of the transducer ~1 meter below water surface. Data were lightly processed, including match filtering onboard the instrument, and computing the envelope of the correlate. Gas throughout the data set disrupts the signal. Funding was provided by the Delta Stewardship Council Delta Science Program under Grant #1167. DOI: 10.26022/IEDA/330932

Description: This gridded bathymetry is the best publicly available rendering of the bathymetry of the entirety of the lake generated to date. The results of this work are presented in: Lyons, et al., 2011, Late Quaternary stratigraphic analysis of the Lake Malawi Rift, East Africa: an integration of drill-core and seismic reflection data, Palaeogeography, Palaeoclimatology, Palaeoecology, v. 303, pp. 20-37. The gridded bathymetry data were generated from lake floor horizons interpreted from legacy multichannel and single-channel seismic reflection data from as early as 1985, and not from hydrographic surveys. Accordingly there is considerable error associated with lake floor horizon picks. Primary data quality varied widely. Positioning information is derived from autonomous GPS data or from Transit Satellite data collected during seismic acquisition, and positioning quality varies widely. See the Lyons et al., 2011 paper for specific information on primary data. Gridding and masking was performed in GMT using the surface function after the data was meaned in blocks of 15 arcsecond (~450m) bins to reduce spatial aliasing and eliminate redundant data. This grid is a minimum curvature solution (i.e. T = 0). Depths are in meters, positive downwards, and are relative to the lake surface. The grid is in GeoTIFF grid format. DOI: 10.26022/IEDA/330928

Description: In July 2019, approximately 217 km of 2-D multichannel seismic reflection data were collected along 27 profiles on Oneida Lake, New York using a 120 channel Seamux™ solid-towed array marine streamer with a 3.125 m group interval and a maximum offset of ~400 meters. Data were recorded in SEG-D format on a NTRS2 recording system. The seismic source was a 4x10 in3 Bolt 2800 LLX airgun array and was towed at ~1 meter depth to allow for venting of seismic source air bubbles. Gun pressures varied from 1500 to 2000 PSI. Air guns were fired every 6.25 m distance using two high resolution (Trimble) GPS receivers for navigation. This geometry provided 30-fold seismic coverage with a common midpoint (CMP) interval of 1.56 m. Record length is 2 seconds and the sample rate is 0.25 ms. These raw field shot data files are in SEG-D format, bundled by seismic line. The files were acquired as part of a project called P2C2: A High Resolution Paleoclimate Archive of Termination I in Oneida Lake and Glacial Lake Iroquois Sediments. Funding was provided through NSF grant EAR18-04460 to Syracuse University. DOI: 10.26022/IEDA/330883

Description: This data set was acquired in 2017-2018 with a 250 kHz Kongsberg Geoswath Phase Measuring Bathymetry Sonar (PMBS) system mounted in the moon pool of R/V Lowell Weicker. Horizontal accuracy was provided by DGPS augmented by RTK corrections from the Advanced Continuous Operation Reference Network (ACORN). This is a Connecticut statewide system of base stations that provides real-time corrections for GPS equipment, operated by the University of Connecticut through a partnership with CTDOT (http://acorn.uconn.edu). Tides were corrected to MLLW based on tide gauge data from NOAA Tide Station at New London, Connecticut (Station ID: 8461490). Sound velocity profiles (SVP) were conducted every three hours to acquire sound speed data using the UConn Valeport SVP system. Data acquisition was performed using the Geoswath+ acquisition software and saved as .rff files for subsequent post-processing. The system recorded bathymetry and sidescan sonar data along with heave, pitch and roll data from a Seatex MRU-5 mounted on the Geoswath transducer. Positional information for all equipment (GPS, transducer, MRU) offsets and latencies can be found in the CARIS vessel file included with the raw data. Line spacing was set at 25 meters for the majority of the survey area with a 30 meter spacing adopted in deeper areas (information provided in the daily Survey Logs). The bathymetry data files were processed using CARIS software. The data files were acquired and processed in two individual blocks. The final bathymetry files presented here are in GeoTIFF image format, projected in WGS84 UTM 18N (EPSG: 32618) with 1m resolution. The data set was collected and assembled as part of the "The Long Island Sound Seafloor Mapping Initiative Phase II – Eastern Long Island Sound" project conducted by the Long Island Sound Mapping and Research Collaborative (LISMaRC, Principal Investigator: Ivar G. Babb).

Description: This is the preliminary data volume that was produced from this NZ3D Hikurangi margin project. This SEG-Y file is a post-stack 3D Kirchhoff migration prior to multiple suppression. The volume was produced from multi-channel seismic lines acquired during the Langseth cruise MGL1801 conducted along the Hikurangi margin in 2018.The goal of this preliminary processing was to conduct sufficient processing for an initial assessment of the data and preliminary interpretation. There is no multiple suppression, and the multiple interferes substantially. The results of this preliminary volume were used only for close examination of shallow structures above the seafloor multiple, and an overall assessment of the main structures below the seafloor multiple. Advanced processing to remove multiples, build accurate velocity models, and conduct prestack depth imaging were efforts that followed this initial volume. The accompanying information document describes the 3D grid parameters including bin grid origin and orientation for workstation loading, the Data Parameters, the SEG-Y trace header, and the processing sequence. The data set was generated as part of the project called "A community 3-D seismic investigation of fault property controls on slow slip along the Hikurangi megathrust". Funding was provided through NSF awards: OCE15-58440, OCE15-58574, OCE15-59008, OCE15-59298. DOI: 10.26022/IEDA/330881

Description: This data set represents processed Multi-Channel Seismic (MCS) profiles acquired in July 1988 with the Digicon recording vessel Geotide. The four versions of data files presented here, in SEG-Y format, are in progressively advanced stages of processing. Processing was carried out at the GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany using PRAKLA-SEISMOS software on a CONVEX computer. The unmigrated time stack (file EDGE_302_stack.sgy) used a standard processing flow of scaling, multiple removal, deconvolution, filtering, Velocity analysis, Normal Moveout, and Stacking. The initial Prestack depth migration (file EDGE_302_tmig2d.sgy) was then performed using depth focusing analysis on migrated common image gather iteratively to build a velocity field in depth. The final prestack depth migration (file EDGE_302_dmig.sgy) had additional weighting of the amplitudes below the top of the oceanic plate and cleaning of remaining multiple energy applied. The final prestack depth migration was converted to time (file EDGE_302_tmig.sgy). The unmigrated time has a CMP interval of 12.5m; all others are 25m. Additional details for each data file are given in the associated data file details document. The project was supported by National Science Foundation Grant EAR87-21194 and Texaco Oil Company.

Description: The data set presents OBS data in segy format. In the SISIE marine seismic reflection and refraction experiment, two long-offset marine seismic refraction lines were gathered in 2018 with R/V Marcus Langseth during cruise MGL1803. These lines are MGL1803OBS01 and MGL1803OBS02. The Langseth shots were recorded by four-component, short-period ocean-bottom seismometers of the University of Texas Institute for Geophysics (UTIG). The direct wave from the shot to the instrument was used for timing corrections and relocation of the instrument on the seafloor. These segy files have been updated with the corrected timing, instrument locations, and source-receiver offsets. This version of the OBS data has not been filtered. The data files are in SEG-Y format and were generated as part of the project called SISIE: South Island, New Zealand, Subduction Initiation Experiment. Funding was provided through NSF grants OCE16-54689 and OCE16-54766. DOI: 10.26022/IEDA/330844

Description: These seismic navigation data were collected on Oneida Lake, New York, in July of 2019 during MCS data acquisition. Two high-resolution Trimble GPS receivers mounted on the port bow provided the location of each FFID or shot point. This information combined with the ship/survey geometry, which included the relative location of the airguns and midpoint of all streamer channels, allowed for calculation of the approximate X and Y coordinates in UTM 18N of the air guns and the midpoint for streamer channel 1 (1st channel) through channel 120 (last channel). The navigation data as well as the geometry of the seismic survey were loaded into Landmark SeisSpace/ProMAX software which produced the X and Y coordinates in UTM 18N for each CDP (common depth point). The data files are in ASCII text format and contain the line name, CDP number, and the UTM 18N X,Y coordinates in meters. The files were generated as part of a project called P2C2: A High-Resolution Paleoclimate Archive of Termination I in Oneida Lake and Glacial Lake Iroquois Sediments.

Description: In July 2019, approximately 217 km of 2-D multichannel seismic reflection data were collected along 27 profiles on Oneida Lake, New York using a 120 channel Seamux™ solid-towed array marine streamer with a 3.125 m group interval and a maximum offset of ~400 meters. Data were originally recorded in SEG-D format on a NTRS2 recording system. Navigational data and ancillary data (ship speed, depth, etc.) were fed into the external header of each field file. The seismic source was a 4x10 in3 Bolt 2800 LLX airgun array and was towed at ~1 meter depth to allow for venting of seismic source air bubbles. Gun pressures varied from 1500 to 2000 PSI. Air guns were fired every 6.25 m distance using two high resolution (Trimble) GPS receivers for navigation. This geometry provided 30-fold seismic coverage with a common midpoint (CMP) interval of 1.56 m. Record length is 2 seconds and the sample rate is 0.25 ms. The following processing steps were applied to the dataset using SeisSpace/ProMAX Software. Data were initially reviewed in shot mode and noisy traces were edited. Geometry was applied using source and receiver offsets with group and shot intervals, and data were sorted into the CMP domain. Stacking velocities were picked using a combination of velocity semblance plots and constant velocity stacks applied to CMP supergathers. For the constant velocity stacks, supergathers were constructed from 51 CMPs and analyzed in increments of 100 CMPs. Once time-velocity pairs were selected, normal moveout was applied to the full profile data set and the data were stacked.Nested Ormsby bandpass filters of 110-135-1500-1700 Hz and 40-70-1100-1300 Hz were applied to the stacked datasets. Ormsby filter frequencies were picked by executing a careful parameter test where frequencies were altered incrementally until the ideal filter was produced. A post-stack F-K filter was applied to remove steeply dipping noise, and a careful comparison of F-K filtered profiles and raw profiles was conducted. A post-stack Kirchhoff time migration with a 200 ms bottom taper was applied using the RMS stacking velocities picked for each seismic profile. The data files are in SEG-Y format and were generated as part of a project called P2C2: A High Resolution Paleoclimate Archive of Termination I in Oneida Lake and Glacial Lake Iroquois Sediments. Funding was provided through NSF grant EAR18-04460 to Syracuse University. DOI: 10.26022/IEDA/330835

Description: Navigation data for the All American Canal CHIRP survey, compiled in a KML format. Data were collected near Calexico, CA in April 2019. The purpose of these data was to image deformation features in shallow sediments in the Imperial Fault system and surrounding regions, to understand strain partitioning and identify locations for geologic slip rate studies. The KML file presented here contains navigational data for each SEG-Y line, obtained from the pole-mounted Septentrio Altus NR3 GNSS receiver. Elevations are of the instrument transducer (corrected for frame and pole mount), and are given as meters relative to sea level. Funding was provided by the Southern California Earthquake Center grant #18119. DOI: 10.26022/IEDA/330518

Description: This microseismicity catalog is derived from three separate local ocean-bottom seismometer networks on the Endeavour Segment of the Juan de Fuca ridge. The earthquake locations in this catalog from the first network, deployed from June-August 1995, are relocations of the Wilcock (2002, doi:10.1029/2001JB000505) earthquake catalog (doi:10.1594/IEDA/306478). Earthquake locations from the second network, deployed from August 2003-October 2006, are relocations of the Weekly et al. (2013, doi:10.1002/ggge.20105) earthquake catalog (doi:10.1594/IEDA/321736). The third network is part of the Ocean Networks Canada NEPTUNE cabled observatory. We include newly-published earthquake locations for this network for August 2016-February 2021 as JdF_Endeavour_earthquake_catalog_v1.txt. The data file is in ASCII text format and the header block describes the content. Not all earthquakes have an estimated moment due to selection criteria. Details of the methods used to locate earthquakes from all three deployments may be found in Krauss et al. (2023, doi:10.1029/2022JB025662). An updated datafile, which includes an extended earthquake catalog from the Ocean Networks Canada NEPTUNE cabled observatory (network code NV) covering August 2016-December 2023, is available as JdF_Endeavour_earthquake_catalog_v2.txt. This version 2 file does not contain earthquakes from 1995 or from 2003-2006. Earthquake moments do not have station corrections applied as in Krauss et al. (2023, doi:10.1029/2022JB025662), but are simply the median of all moment estimates between stations. The data set was generated as part of the project titled "Microearthquakes on the Endeavour Segment, Juan de Fuca Ridge: A Near Real Time Earthquake Catalog for the ONC Cabled Observatory and a Reanalysis of Historical Data". Funding was provided by NSF grant OCE-1833419. DOI: 10.26022/IEDA/330498

Description: Catalog of T-phase origins from August 2011 to January 2015, located using waveform arrivals recorded by an array of 8 autonomous moored hydrophones and the hydroacoustic station HA10 (Ascension) maintained by the Comprehensive Nuclear-Test-Ban Treaty Organization. Instruments were placed in the Sound Fixing And Ranging (SOFAR) channel. Event locations are expected to be associated with earthquakes on transform faults and spreading segments along the equatorial Mid-Atlantic Ridge. The data file is in ASCII text format and contains a header line that describes the file content. The data set was generated as part of the projects called Seismicity of the Equatorial Mid-Atlantic Ridge and Its Large Offset Transforms; and, Along-Axis Continuity of Oceanic Detachment Faults. Funded was provided by NSF awards NSF EAR-1062238, EAR-1062165, and OCE-1839727. DOI: 10.26022/IEDA/330497

Description: This data set (investigators D. W. Caress, D. A. Clague, J. B. Paduan, M. Le Saout) is compiled from data collected on surveys of the South Rift Zone at Axial Seamount between 2011 and 2019 by the MBARI Mapping AUVs. This data set is as published in Le Saout et al., 2022, Faulting and magmatic accretion across the overlapping spreading center between Vance Segment and Axial South Rift, GRL. The bathymetry is interim and to be considered a work in progress. The navigation model underlying this version of bathymetry was generated on 31 October 2019 using the MB-System mbnavadjust program, with which the AUV surveys are tied together. As future data are acquired, the bathymetry coverage will increase and the navigation model will shift. This raster data file is in GeoTIFF image format in the geographic WGS-1984 coordinate system and has 1-m horizontal resolution, with square cells for use with GIS. The GeoTIFF image is slope-shaded using the Haxby color ramp with the depth range that was used in Figure 1 of LeSaout et al., 2021: -2600 to -2000 meters. Funding for the work was provided through annual grants to MBARI from the David and Lucile Packard Foundation. DOI: 10.26022/IEDA/330467

Description: This geological interpretation of lava flows outlines, faults, and eruptive fissures (investigators D. W. Caress, D. A. Clague, J. B. Paduan, M. Le Saout) is compiled from data collected on surveys of the South Rift Zone at Axial Seamount between 2011 and 2019 by the MBARI Mapping AUVs. This data set is as published in Le Saout et al., 2022, Faulting and magmatic accretion across the overlapping spreading center between Vance Segment and Axial South Rift, GRL. The flows shapefile provides outlines of lava flows erupted about 1300 to 1450 years ago and of three younger flows on the South Rift Zone of Axial Seamount. The data files are in shapefile format in UTM Zone 9N projection. Funding for the work was provided through annual grants to MBARI from the David and Lucile Packard Foundation.

Description: This data set was acquired with a High Tech HTI-90-U hydrophone and sampled at 44.1 kHz (24-bit). The hydrophone and data logger were packaged and lowered to the floor of Yellowstone Lake at a depth of ~115 m from R/V Annie, owned and operated by The Global Foundation for Ocean Exploration. The unit was placed in a weakly venting area of the Deep Hole thermal field. Recording began several hours before the unit was deployed in the lake. Only those files that contain data from the hydrothermal field are archived here. The unit was deployed on August 16, 2017 at the end of a day of field work, prior to departing the study site, and recorded overnight, when noise levels in the lake are lowest. The unit was then recovered the following morning (August 17) prior to the start of field work that day. In addition to data from the sublacustrine environment, ship and propeller noise is clearly audible in the records during deployment and recovery, but noise levels are low during the local (MDT) nighttime hours. The files are in WAV audio file format. Recorder voltage response is 978000 counts/volt. The data were acquired by Robert Sohn (Woods Hole Oceanographic Institution) as part of the Hydrothermal Dynamics of Yellowstone Lake (HD-YLAKE) project, funded by the National Science Foundation, EAR-1516361. All work in Yellowstone National Park was completed under an authorized research permit (YELL-2018-SCI-7018). DOI: 10.26022/IEDA/330446

Description: This processed bathymetry data set was generated from multibeam data obtained from LINZ Data Service. The data file is in GeoTIFF grid format and is in the New Zealand Transverse Mercator 2000 (EPSG:2193) projection. The original multibeam data was collected with a multibeam instrument (model unknown) between August 2008 and March 2009 by a contractor working on behalf of Land Information New Zealand (LINZ). The multibeam line spacing in the original survey was 100m. The original multibeam data was converted to XYZ format and released by LINZ to the University of Otago under the Creative Commons 4.0 license. The XYZ files were uploaded to ArcGIS Pro and converted to a 1m x 1m bathymetric raster grid of Paterson Inlet using the Create ArcGIS TIN and TIN to Raster Toolboxes. This bathymetric grid was created to give students, particularly those at the University of Otago, a way to easily access bathymetric data for the Paterson Inlet, an area that is often used for teaching and research purposes.

Description: This microseismicity catalog is derived from data retrieved from ocean-bottom seismometers deployed in 2008 as part of the Quebrada-Discovery-Gofar (QDG) Transform Fault Experiment. The data files are in ASCII format. The first row is a column header that describes the content of the catalog: Earthquake origin time, latitude, longitude, depth and local magnitude. Not all earthquakes have a local magnitude estimate because of the selection criteria. Details of the earthquake location methodology and location interpretations can be found in the paper "Microseismicity indicates atypical small-scale plate rotation at the Quebrada transform fault system, East Pacific Rise" by Gong et al., GRL. The data set was generated as part of the projects called Oceanic Transform Faulting: Foreshocks, Seismic and Aseismic Slip on the Quebrada, Discovery and Gofar Transforms; and, Capturing 4D Variations in Stress, Slip, and Fault-Zone Material Properties: The 2019-2021 Gofar Transform Fault Earthquake Prediction Experiment.

Description: This data set consists of raw hydrothermal high-temperature vent time-series measurements from Multidisciplinary Instrumentation in Support of Oceanography (MISO) vent fluid temperature loggers deployed in 2004 during R/V Atlantis cruise AT11-09 at M vent and Q vent at the East Pacific Rise (EPR), near 9° 51'N. The MISO high-temperature vent fluid loggers used for this study contained two Onset Computer (https://www.onsetcomp.com/) temperature recording chips connected to resistance temperature device (RTD) sensors, each with a resolution of 1°C. The sensing capability of this instrument was limited to the range between 152–408°C because they are 8-bit devices [see Fornari et al. (1998a) for instrument details]. Exit-vent fluid temperatures were recorded continuously over more than 20 months at 36 minute intervals. These raw data files contain the raw data as downloaded from the instruments upon recovery. The files are in tab-separated ASCII format and include a header that defines the data columns: First column = Date Time; Second column = Temperature in Degrees Celsius. In the file names, 623721 and 623731 refer to the ONSET temperature logging chip serial number. The data set was collected as part of the projects called Integrated Studies of Biological Community Structure at Deep-Sea Hydrothermal Vents; Temporal Variations in Hydrothermal Fluid Chemistry at 9-10N East Pacific Rise: Elucidating Ties to Crustal and Biological Processes; Evaluation of EPR Hydrothermal Systems: Causes of Continued Chemical Instability at 9-10 degrees N vs. Stability at 21 degrees N; and, Faunal Survey of Deep-Sea Hydrothermal Vents and Cold Seeps Off Northern California and Oregon. The data acquisition was funded through NSF awards DEB00-72695, OCE00-02458, OCE03-27126, OCE03-27261. Current analysis of these data and ongoing studies of EPR high-temperature vent fluids and time-series temperature measurements are being done with NSF awards OCE18-34797, OCE19-48936, OCE19-49485, OCE19-49938 as part of the projects called EAGER: Early Career Training Cruise Opportunity - East Pacific Rise 9° 50'N; and, Monitoring hydrothermal fluids, crustal permeability and seafloor morphology in preparation for the next volcanic eruption at the East Pacific Rise, 9° 50'N.

Description: This sub-bottom data set was collected with an ODEC Bathy2000 hull-mounted sub-bottom CHIRP system in 2001 during Palmer cruise NBP0101 (chief scientist Amy Leventer). These are KMZ files created from groups of hourly SEG-Y files that were lightly processed and clumped into groups spanning approximately 12 hours. See the accompanying sub-bottom data processing report for details. The primary purpose of the cruise was to investigate the relatively unexplored East Antarctic continental margin, from the Wilkes Land region to the Mac.Robertson shelf, searching for, and sampling, high resolution sedimentary records. The data set was created as part of the project called Quaternary Glacial History and Paleoenvironments of the East Antarctic Margin. Funding was provided through NSF awards OPP01-96389, OPP99-09367, OPP99-09793, OPP99-09837. DOI: 10.26022/IEDA/330387

Description: This sub-bottom data set was collected with an ODEC Bathy2000 hull-mounted sub-bottom CHIRP system in 2001 during Palmer cruise NBP0101 (chief scientist Amy Leventer). These are shapefiles created from groups of hourly SEG-Y files that were lightly processed and clumped into groups spanning approximately 12 hours. See the accompanying sub-bottom data processing report for details. The primary purpose of the cruise was to investigate the relatively unexplored East Antarctic continental margin, from the Wilkes Land region to the Mac.Robertson shelf, searching for, and sampling, high resolution sedimentary records. The data set was created as part of the project called Quaternary Glacial History and Paleoenvironments of the East Antarctic Margin. Funding was provided through NSF awards OPP01-96389, OPP99-09367, OPP99-09793, OPP99-09837. DOI: 10.26022/IEDA/330386

Description: Bathymetric data were collected during a total of 19 AUV Sentry dives conducted from R/V Atlantis and R/V Roger Revelle during 2018 Atlantis cruise AT42-06 (two dives); 2019 Atlantis cruise AT42-21 (ten dives); and, 2021 Revelle cruise RR2102 (seven dives). Track lines were spaced 170 m apart, with Sentry about 65 m above bottom, collecting multibeam data using a 400 kHz Reson 7125 system in 2018, and a 400 kHz Kongsberg EM2040 system in 2019 and 2021. Sentry navigation was obtained using a 300 kHz Teledyne Doppler velocity log (DVL) and a Sonardyne AvTrak2 ultra-short baseline (USBL) acoustic positioning system, combined with an iXblue Phins inertial navigation system (INS), and a Paroscientific 8B7000-I Digiquartz depth sensor. Sonar data from all 19 dives were processed together using the open-source MB-System software, and were gridded at 1 m × 1 m node resolution using a beam footprint calculated with the angular beam widths and weighted by local slope. The grid file is in GMT-compatible netCDF format, in un-projected geographic coordinates. Funding was provided by National Science Foundation awards OCE-1834797, OCE1949485, OCE-1948936, and OCE-1949938. DOI: 10.26022/IEDA/330373

Description: This ultra-short baseline (USBL) navigation data set captures the position of the front of a deep-towed electromagnetic instrument array deployed in November 2020 during mapping of gas hydrate in the Pegasus Basin, New Zealand. There were two deep-tow dives, called senko_01 and senko_02, and the navigation for both is merged in this one data file. The file is in ASCII text format, with each line consisting of year, month, day, hour, minute, second, latitude, longitude, depth (m). The data file was generated as part of a project called Marine CSEM study of the southern Hikurangi Margin: A first step towards estimating the global gas hydrate carbon budget. Funding was from NSF award OCE-1916553. DOI: 10.26022/IEDA/330281

Description: These raw, deep-towed electric field time series data files were collected in November 2020 during controlled-source electro-magnetic mapping of gas hydrate in the Pegasus Basin, New Zealand. They were collected using five SIO Mk III OBEM Vulcan recorders named Barramundi, Mahi, Mola, Morwong, and Mullet. These five Vulcan receivers were deep-towed as an array, spaced at 200 m intervals in that name order, during two data acquisition dives called senko_01 and senko_02. The data file names are distinguished based upon the dive name and Vulcan receiver name. Between the two dives, the data files were downloaded and the instrument batteries were replaced. Data files are in the Scripps EM data logger binary format, with Ch1 = crossline electric, Ch2 = inline electric, Ch3 = vertical electric, Ch4 = CSEM timing signal. The instruments, data format, and playback software are described at https://marineemlab.ucsd.edu/instruments/. These data files were generated as part of a project called Marine CSEM study of the southern Hikurangi Margin: A first step towards estimating the global gas hydrate carbon budget.

Description: Identifications of magnetic reversals from Anomaly 1 (0.78 Ma) to Anomaly 26 (~59 Ma) from a wide range of shipboard and airborne magnetic data from the India-Somalia portion of the Carlsberg Ridge and Central Indian Ridge are embedded in a text file along with fracture zone (and transform fault) traces that were digitized from best-available bathymetric and satellite gravity data. These include all the data that were used to estimate the high-resolution India-Somalia plate rotation sequence described by DeMets et al. (2021). A detailed description of the file contents is found at the start of the file. The data file is in ASCII text format and was generated as part of a project called Toward an understanding of Neogene plate dynamics: Completion of a high-resolution, closure-enforced chronology of global plate motions since 20 Ma. Funding was provided through NSF award OCE14-33323 and Russian Foundation grant 05-04-64297. These data have large overlap with the data associated with data DOI: 10.26022/IEDA/329895, but supersede the earlier data. DOI: 10.26022/IEDA/330268

Description: This file contains the command script that was used to generate the bathymetry grids and images in this compilation. The command script file is in ASCII format. The grids and images were generated from data collected on 46 AUV surveys performed between 2006 and 2020 by the MBARI Mapping AUVs and the AUV Sentry operated by WHOI. The data set is interim and to be considered a work in progress. Funding for the work was provided through annual grants to MBARI from the David and Lucile Packard Foundation and grants from the Ocean Sciences Division of the National Science Foundation (awards NSF OCE-1356839, NSF OCE-1737019) to David W.

Description: This data set (investigators D. W. Caress, D. A. Clague, J. B. Paduan) is compiled from AUV mapping data collected on 46 surveys between 2006 and 2020 by the MBARI Mapping AUVs and the AUV Sentry operated by WHOI. The data set is interim and to be considered a work in progress. The navigation model underlying this version of bathymetry was generated on 10 March 2021 using the MB-System mbnavadjust program, with which the surveys are tied together. As future data are acquired, the bathymetry coverage will increase and the navigation model will shift. The "MAUV*All*" bathymetry grids were constructed by stacking (with GMT grdmath "AND" function) year-by-year grids so that the more recent data are on top and thus later coverage supercedes coverage collected prior to the 2011 and 2015 eruptions. The "MAUV*OverEM302*" grids were made from the AUV composite grid stacked above a bathymetry grid made from data collected with EM302 multibeam sonars aboard the R/Vs Thompson and Kilo Moana. All are in the geographic WGS-1984 coordinate system and gridded at 1-m horizontal resolution, as square cells for use with GIS. The data files in this data set are in ESRI ASCII grid format.

Description: This data set consists of a series of 11 gravity measurements, made on the seafloor across the TAG hydrothermal mound on the Mid-Atlantic Ridge near 26N, 45W. Data were collected in 1994 as part of the 1994 R/V Yokosuka cruise called MODE-94 (chief scientist was Kantaro Fujioka).The measurements were made using a Scintrex CG-3 Autograv system installed inside the Japanese Shinkai 6500 submersible. Details of the data and their analysis can be found in Evans (1996). A full inversion of the data alongside a newly-collected magnetics data set can be found in Galley et al. (2021). The data were first levelled using the northern-most station as a reference point, then processed to develop the free-water anomaly. The forward signal of a background model built with 2m resolution bathymetric data of the seafloor about the mound, with density 2.4 g/cm3 (Evans, 1996), was then removed to produce the Bouguer anomaly data included in the file. The data file is in ASCII tab-separated format with seven columns: Longitude, Latitude, Easting [meters, UTM zone 23N], Northing [meters, UTM zone 23N], Elevation [meters], Bouguer Anomaly [mGal], Raw Data [mGal].

Description: Hurricane Florence made landfall as a Category 1 near Wilmington, NC on the morning of September 14, 2018. Hurricane-force winds were experienced over a large region, yielding powerful storm surge and waves over 8 m offshore. The overarching objective of the project was to collect seafloor mapping data and sediment samples over a previously surveyed portion of the Morehead City Ocean Dredged Material Disposal Site (ODMDS) to assess shelf sediment reworking associated with Hurricane Florence. The project collected geophysical data and sediment samples over a portion of the ODMDS offshore of Bogue Banks, NC in early 2019. Geodynamics LLC was contracted and collected a suite of multibeam bathymetry, backscatter and seismic reflection data along with sediment samples. These data sets add to previously collected information over the same area in 2013 and 2018. The multibeam bathymetry data set was collected on January 15, 2019 aboard R/V Benthos with pole-mounted dual-head EM2040C-D sonars, an Applanix Pos MV inertial measurement unit and real-time kinetic GPS for positioning. Hypack software was used for navigation. The Kongsberg SIS 4.3.2 system was employed for multibeam data acquisition, and CARIS HIPS/SIPS was used for data processing. The data file is in GeoTIFF grid format and the final grid horizontal resolution is 5 ft (1.52 m). Funding was provided by an NSF RAPID grant titled "RAPID: Examining Seafloor Dynamics offshore Bogue Banks, North Carolina, Related to Hurricane Florence", Award OCE 1906073 to lead investigator J.P.

Description: This data file presents the projected composite profile of magnetic anomaly values upward-continued to a level plane at 3.2 km water depth and to the sea surface. To generate the composite profile, all of the magnetic anomaly data values from the DeepTow-MISO sled tows were projected onto one profile with a strike of 56 (214) degrees and re-sampled to have equally-spaced data points at a 100 m spacing. The deep-tow magnetics data was collected with a total field SeaSPY precession magnetometer attached to the DeepTow-MISO towed sled during the 2011 Thompson cruise TN272 to the western Pacific (chief scientists Masako Tominaga and Maurice Tivey). This processed data file is in ASCII format, with column headers, and gives the projected longitude, latitude, and depth, the projected magnetic anomaly (IGRF removed), and the upward-continued anomalies at a depth of 3,200m and at the sea surface. The data set was generated as part of the projects called A Deep-AUV Magnetic and Seismic Study of the Hawaiian Jurassic Crust - The Global Significance of Jurassic Magnetic Anomalies; and, A High-Resolution Deep-AUV Magnetic Survey of the Hawaiian Jurassic Basin.

Description: Hurricane Florence made landfall as a Category 1 near Wilmington, NC on the morning of September 14, 2018. Hurricane-force winds were experienced over a large region, yielding powerful storm surge and waves over 8 m offshore. The overarching objective of the project was to collect seafloor mapping data and sediment samples over a previously surveyed portion of the Morehead City Ocean Dredged Material Disposal Site (ODMDS) to assess shelf sediment reworking associated with Hurricane Florence. The project collected geophysical data and sediment grab samples over a portion of the ODMDS offshore of Bogue Banks, NC in early 2019. Twenty-one surface sediment samples collected on February 26, 2019 were analyzed with a laser diffraction Mastersizer 3000 instrument. Percentages were adjusted for the pre-sieved gravel (>2 mm) fraction. The data files are in ASCII comma-separated format, with column headers. Funding was provided by an NSF RAPID grant titled "RAPID: Examining Seafloor Dynamics offshore Bogue Banks, North Carolina, Related to Hurricane Florence", Award OCE 1906073 to lead investigator J.P.

Description: The JC066 swath bathymetry data was acquired with a hull-mounted Kongsberg-Simrad EM120 multibeam echo sounder in 2011 during James Cook cruise JC066 (chief scientist Alex David Rogers). The bathymetry survey focussed on a number of seamounts along the Southwest Indian Ridge and was designed to minimise shadow zones over the summits and to reduce the effects of bubble entrainment, However, adverse weather conditions resulted in poor-quality backscatter for two sites, Coral and Melville. Shipboard editing of acquired data was conducted in CARIS HIPS and SIPS, incorporating navigation and sound velocity corrections. The .all files are available from the British Oceanographic Data Centre (BODC), and further manual processing was conducted in Qimera 2.3.1 and Mb System (swath bathymetry) and FMGeocoderToolbox (FMGT) 7.9.5 (backscatter) to remove erroneous data points. Backscatter data for the Coral and Melville sites was subsequently filtered in QGIS 3.12 to reduce the strength of data artefacts. The grids were generated at a horizontal resolution of 25m and cover the areas of Atlantis bank, Coral seamount, Melville seamount, Sapmar seamount and "Middle of What" seamount. The files are in GMT-compatible netCDF grid format. Funding for the work was provided through a UK-NERC grant. DOI: 10.26022/IEDA/330100

Description: Bathymetry data was collected with a hull-mounted Reson SeaBat 7160 sonar during M/V Alucia 2015 cruise AL150801 (chief scientist Adam Soule). Navigation was from ship-mounted GPS. The raw bathymetry data was collected in Reson s7k binary format. Minimal cleaning of data was done so the resultant grids may contain spikes. The bathymetry values were corrected for tides and for water column velocity. The grids are in GMT-compatible netCDF format. The data set was generated as part of the project called Rise and Fall of Galapagos Seamounts. Funding was provided through the Dalio Family Foundation and through NSF award OCE16-34685.

Description: This is a time-processed 3-D multi-channel seismic data volume collected on the mid-continental shelf roughly 40 to 90 km off the coast of central New Jersey, USA. The data are within a rectangular area roughly 11.1 x 50 km, oriented NW-SE in 30 to 60 m water depths, collected in June-July, 2015 during cruise MGL1510. Chief Scientists were G.Mountain, M. Nedimovic, C.Fulthorpe and J.A.Austin, Jr. Acquisition was managed by Lamont-Doherty Earth Observatory (R.Steinhaus, Ch.Sci.Officer) with sub-contracts to Geometrics (PCable seismic acquisition) and NCS-SubSea (seismic navigation). A single 3 km streamer was trailed to provide acoustic velocity measurements. Twenty-four 50 m PCables were towed from a 287-m cross cable. The seismic source was a tuned array of 4 conventional airguns of 700 cu. in. total volume towed from a centerline float. Data were collected along 50-km sail lines in SEG-D format in 0.5 ms samples from 0 to 4 s two-way travel time; this was resampled to 1 ms and 1500 ms record lengths post-cruise. Pre-stack processing included filtering, trace editing, statics and amplitude correction, assigning geometry and 3D CDP binning to 3.25 m x 6.25 m, and signature decon to provide source-receiver statics correction. Full volume processing included Surface-Related Multiple Elimination, FK filtering, Post-Stack Kirchhoff Time Migration, 3D filtering, wavelet shaping, balancing and filtering. The accompanying PDF document describes the data processing steps and the work station loading information for the 3-D seismic volume. The data set was generated as part of a project called Community-Based 3D Imaging That Ties Clinoform Geometry to Facies Successions and Neogene Sea-Level Change. Funding was provided by NSF award OCE-1260237. DOI: 10.26022/IEDA/329943

Description: Three 2-D line segments from ALEUT cruise MGL1110 have been processed by the USGS to the point of migrated depth and used for figures in the von Heune et al., 2020 G-Cubed publication. The processing was done using ProMAX seismic data processing software on Linux/Redhat hardware. Processing steps and navigation details about these processed lines are given in the accompanying PDF file called "Data_Description_Processing_Flow_Navigation_Notes". These processed seismic files are in SEG-Y image format and navigation is the same as that in the P190 processed navigation files. However, these processed SEG-Y data files are subsets of the original lines and do not have the navigation coordinates stored in their trace headers. The processed lines can be located along the original track lines by using the table in the PDF document. The original seismic data was collected in 2011 with the LDEO Multi-Channel Seismic system during Langseth cruise MGL1110 as part of the ALEUT (Alaska Langseth Experiment to Understand the megaThrust) project. Chief Scientist on the cruise was Donna Shillington. Refer to Cruise MGL1110 for complete acquisition details. DOI: 10.26022/IEDA/329922

Description: This data set was acquired with a 250 kHz Kongsberg Geoswath Phase Measuring Bathymetry Sonar (PMBS) system equipped mounted in the moon pool of R/V Lowell Weicker. Horizontal accuracy was provided by DGPS augmented by RTK corrections from The Advanced Continuous Operation Reference Network (ACORN). This is a Connecticut statewide system of base stations that provides real-time corrections for GPS equipment operated by the University of Connecticut through a partnership with CTDOT (http://acorn.uconn.edu). Tides were corrected to MLLW based on tide gauge data from NOAA Tide Station at New London, Connecticut (Station ID: 8461490). Sound velocity profiles (SVP) were conducted every three hours to acquire sound speed data using UConn's Valeport SVP system. The system recorded bathymetry and sidescan sonar data along with heave, pitch and roll data from a Seatex MRU-5 mounted on the Geoswath transducer. Positional information for all equipment (GPS, transducer, MRU) offsets and latencies can be found in the CARIS vessel file included with the raw data. Line spacing was set at 25 meters for the majority of the survey area with a 30 meter spacing adopted in deeper areas (information provided in the daily Survey Logs). Data acquisition was performed using the Geoswath+ acquisition software and saved as .rff files for subsequent post-processing. Each survey segment zipped file contains raw and auxiliary (sound velocity profiles, tides) data. The data were collected and assembled as part of the "The Long Island Sound Seafloor Mapping Initiative Phase II – Eastern Long Island Sound" project conducted by the Long Island Sound Mapping and Research Collaborative (LISMaRC, Principal Investigator: Ivar G. Babb). Funding provided by the Long Island Sound Seafloor Mapping Fund administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).

Description: This data set consists of log10 values of machine-learning-based mass accumulation rates and linear uncertainty on the seafloor, globally. The Geospatial Predictive Seafloor Model (GPSM) of the United States Naval Research Laboratory was trained on real-world observations from 43 peer-reviewed sources (n = 1744) to predict marine mass accumulation rates on a 5-arc-minute map using a k-nearest neighbor algorithm. Original (non-log space values) are in g/cm2/yr. The model and results are described in Restreppo et al. (2021). The data files are in netCDF (.nc) grid format. The file called Log10_prediction_5m.nc contains the predicted sediment accumulation rate in log10(g/cm2/yr). The file called Linear_uncertainty_5m.nc is the uncertainty, in g/cm2/yr.

Description: In the framework of the Interreg Ita-Slo 2007-2013 TRECORALA Project, a two-year research and data collection campaign was performed (2012-2014). The purpose of the TRECORALA project was to broaden the biological knowledge of the "Trezze"/"Grebeni" and coralligenous seabeds of the Gulf of Trieste and to identify guidelines for the management, protection and enhancement of this natural environment, strengthening the attractiveness and competitiveness of the area and contributing to safeguarding biodiversity. Through the collected information on professional fishing activities, management proposals were made regarding some resources of particular commercial interest. As a final product, the project provided the necessary tools for the joint cross-border management of marine areas, also developing the tourism sector.This multidisciplinary study presents the major characteristics of a set of submarine rock outcrops in the Northern Adriatic Sea: the rock occurrence, embedded down to about 1 m from the seafloor in the bottom sediments; several gas accumulations in the proximity of the outcrops (e.g., bubbling gas from the sediment–water interface); small-scale mud volcanoes; and microbial mats around the seepage site. Geochemical analysis revealed that these features are related to the seepage of CH4-rich fluids, which causes the precipitation of methane-derived calcium carbonate as a cement. A variety of benthic specimens contributes to their growth, including bryozoans, molluscs, serpulid polychaetes, scleractinians and calcareous algae, the latter acting as the main bio-constructors. The site is characterized by the presence of localized coralligenous buildups, widespread along the northwestern Adriatic Sea inner shelf between depths of 10-27 m. These rocky build-ups rise to 3 m above the sandy-mud seafloor and have a patchy distribution. The study area was mapped using Reson SeaBat 7125 and 8125 multibeam systems to localize the rocky outcrops and to distinguish between soft and hard substrates. The multibeam surveys were conducted from a small boat, named Anthea, using differential GPS for navigation. Sea waves were not perfectly corrected by the inertial system. Here we present the maps of the main outcrops monitored in the Northern-most Adriatic area. The processed data files were gridded at 2 m resolution. The files are in GeoTIFF grid format, projected in the UTM33 WGS84 system. DOI: 10.26022/IEDA/329903

Description: This data set consists of thermal gradients and thermal conductivity to compute the heat flux in Pescadero Basin, Gulf of California. The data have been processed to convert from resistance to temperature using calibrations for each thermistor. Heat flow was estimated by combining the thermal gradient and thermal conductivity using the Bullard method. The data set was collected using a custom 1-m long ROV heat flow probe from Andrew Fisher, UC Santa Cruz. The heat flow probe was deployed on dives S0193-S0199 with ROV SuBastian during Falkor cruise FK181031, operated by Schmidt Oceanographic Institute. Each deployment of the heat flow probe lasted approximately 15 minutes. The data file is in tab-separated ASCII text format with column headers and units; the header block gives explanatory notes. The data set was generated as part of a heat flow study in the Gulf of California and was supported by National Science Foundation grant OCE16-34536 to Rob Harris. DOI: 10.26022/IEDA/329884

Description: This data set presents sidescan sonar grid mosaics. The sidescan sonar data set was collected using the Scripps Institution of Oceanography (SIO) deeply towed instrument package (Deep Tow) at 17°S and 19°S, East Pacific Rise, during cruise PANR06MV (May 1998, chief scientist Jeff Gee). The Deep Tow platform carried a 110 kHz sidescan sonar. The binary data files were originally recorded in SIO fish6 format, and were converted to the MB-System-compatible .mb71 format (mbio format 71) for processing. Processing steps included translating time-based sonar data into backscatter records, and laid out into a regular array of pixels that were projected onto a flat seafloor model (swath bathymetric data were not collected). Data were corrected for the variation of amplitude with grazing angle, filtered with a Gaussian mean low-pass filter (across track /along track dimensions of 11 and 3 pixels, respectively), and mosaiced. Processing was carried out with MB-System release 5.7.6, with mosaics for each profile, organized by day, provided as GMT-compatible netCDF grids. The file name letters ZSsCF mean that the time-based Sidescan sonar data were laid out into a regular array of pixels on the seafloor (i.e. depth, Z), mosaiCed, and Filtered. The data set was generated as part of the projects called Short Wavelength Magnetic Variations within the Central Anomaly on the Southern EPR, and Along-Axis Continuity of Oceanic Detachment Faults.

Description: This data set presents the calibration sheets that accompany the Absolute Pressure Gauge (APG) data from a set of seafloor benchmarks running trench-perpendicular on the Cascadia margin, offshore central Oregon, beginning in 2015. The information in the calibration sheets was used to convert the APG pressure and temperature time series data from counts to physical units. The pressure gauge sensors were made by Paroscientific and the platforms were designed and deployed by the University of Washington School of Oceanography and Applied Physics Lab (APL). The sensors were attached to free-fall deployed concrete benchmarks designed to also serve as a platform for the Scripps Institution of Oceanography’s Absolute Self-Calibrated Pressure Recorder (ASCPR), to obtain campaign-style drift-free reference pressures (not included in this data set). APGs collect absolute pressure (PSIA, dbar) and temperature (degrees C) data at a period of 100 seconds, and were deployed with battery packs and data storage sufficient for 10 years of data collection. The calibration sheets are in PDF format. There is one calibration sheet for each sensor. This data set was generated as part of the project called Constraints on Interseismic Deformation Offshore Oregon from Calibrated Continuous Pressure Records. Funding was provided through NSF award OCE15-58477. DOI: 10.26022/IEDA/329854

The data were transferred in-situ via wireless communication with an ROV. Each data file is in ASCII comma-separated format and contains continuous time series data from a single sensor. No processing has been done beyond the conversion from counts to physical units - see the calibration sheets in the associated data set. Some sensors failed in 2016 and were redeployed the following year, resulting in separate data files. Instrument deployment and recovery operations were performed during cruises TN332, SKQ201607S, SKQ201705S, RR1716.

Description: This data set comprises forward-looking still image photographs of the seafloor from the ROV Jason II SuperScorpio camera. The Jason II dives were part of a research expedition to investigate the products of the 2012 eruption of Havre Volcano in the Kermadec Arc and was conducted in 2015 with ROV Jason II and AUV Sentry during Revelle cruise RR1506 (chief scientists Rebecca Carey, Adam Soule). A total of 12 ROV Jason II dives took place in and around the caldera. The pan, tilt, and zoom of the SuperScorpio camera was controlled by the science party. The camera captured one photograph every 10 second but to keep the number of photos manageable, only one photo per minute is presented here. Each image is 12 mega-pixels in size and the file name contains the time of collection. The corresponding position can be obtained from the Jason II navigation and along-track data files. The photographs were collected as part of the project called Elucidating Conduit, Eruption, and Pyroclast Transport Dynamics of Large Silicic Submarine Eruptions. Funding was provided from NSF awards OCE13-57216 to Adam Soule and OCE13-57443 to Bruce Houghton and Rebecca Carey. DOI: 10.26022/IEDA/329851

Description: This data set consists of thermal gradients and thermal conductivity to compute the heat flux. Determinations of heat flux are in and around the Stevenson Island vent field, Yellowstone Lake, Yellowstone National Park, USA. The data have been processed to convert from resistance to temperature using calibrations for each thermistor. Heat flow was estimated by combining the thermal gradient and thermal conductivity using the Bullard method. The data set was collected using the ROV heat flow probe from the WHOI Deep Submergence Facility. The heat flow probe was deployed with ROV Yogi from R/V Annie which was operated by Global Foundation for Ocean Exploration. Each probe deployment lasted approximately 15 minutes. The data file is in comma-separated ASCII format and the first row gives the column headers and units. The data set was generated as part of the Hydrothermal Dynamics of Yellowstone Lake (HD-YLAKE) project and was supported by National Science Foundation under grant EAR-1515283.

Description: In the framework of the IPA Adriatic DeFishGear project (Derelict Fishing Gear Management System in the Adriatic region, www.defishgear.net), a two-year campaign for monitoring the typologies, abundance and distribution of marine litter in the Natura 2000 site "Tegnùe di Chioggia" (https://natura2000.eea.europa.eu/Natura2000/SDF.aspx?site=IT3250047) was performed. The site is characterized by the presence of localized coralligenous buildups, widespread along the northwestern Adriatic Sea inner shelf between 10 and 40 m depths. These rocky buildups rise up to 3–4 m above the sandy-mud seafloor and have a patchy distribution. A variety of benthic calcareous constituents contribute to their growth, including bryozoans, molluscs, serpulid polychaetes, scleractinians and calcareous algae, the latter acting as the main bio-constructors. According to the European Habitats Directive (92/43/EEC), the marine rocky outcrop classification is included in the Annex I habitat types as "1170-Reefs" and "1180-Submarine structures made by leaking gases". The data on marine debris was collected with a Remotely Operating Vehicle (ROV) during two expeditions performed in May–June 2014 and July 2015 onboard the R/V Astrea of the Italian National Institute for Environmental Protection and Research (ISPRA) (Melli et al. 2017). The study area was mapped using a Kongsberg EM 2040 Multibeam (Kongsberg, Norway) to localize the rocky outcrops and to distinguish between soft and hard substrates. Here we present the maps of the main outcrops monitored in the site "Tegnùe di Chioggia" as well as other scattered outcrops in the area nearby. The processed data files were gridded at 0.5m resolution. The image files provided here are in GeoTIFF image format. DOI: 10.26022/IEDA/329816

Description: These annotated GeoTIFF images of processed bathymetry were generated from single-beam sonar data collected in 2003-2007 as a part of ecological surveys carried out by the University of Bologna, Italy. The bathymetry data was acquired using a Lowrance HDS sonar operating at 200 kHz coupled with a WAAS-enabled D-GPS for navigation, and was processed by means of the kriging interpolation method using Surfer Golden Software. In most cases, the XY grid spacing was set at 0.5 m, but, in some cases according to areal coverage of data, was set to finer or coarser spacings: 1 m for TC2, Term14, TM1, TM4); 2 m for P208; and, 0.1 m for TSO. Depth values were tide-corrected and referred to the Mean Lower Low Water (MLLW) based on astronomical tide prediction (calculated by WXTide32 software using harmonic data for the nearest available station, i.e. Chioggia or Malamocco). The grid projection is in WGS84 / UTM Zone 33N (EPSG:32633). These bathymetry images are provided in GeoTIFF image format and correspond to the associated ESRI ASCII bathymetry grids in the related data set. The lead investigator for this project was Massimo Ponti. DOI: 10.26022/IEDA/329814

Description: These seafloor bottom video clips were collected as part of the Long Island Sound mapping phase 2 project. During three surveys in 2017 and 2018 aboard the research vessels Pritchard and Seawolf, a GoPro Hero 6 video camera was mounted on the frame of a sediment grab device. The camera was set to record video during the sediment sampling operations. The videos were processed using open-source Shotcut software (www.shotcut.org). The videos were clipped to focus upon the time that the sediment grab was close to the seafloor. These video clips are in MP4 format. Still images extracted as frame grabs from these videos are available as a related data set. During the first survey, in 2017, the camera was deployed without external lights and the image was dark below water depths of 8-10m. As result there are some grab stations for which no usable bottom videos exists. For the later surveys, external artificial lights were deployed (Sola video lights, model 3800). These lights allowed video images to be collected in deeper waters. The location of each JPEG image was tagged with the coordinate information for the corresponding sediment grab station. Location information is based on DGPS navigation using the ship GPS antenna. Lateral offset between the ship GPS antenna and the grab sampling device, and drift of the grab sampling device in the water, have not been corrected. The resulting uncertainty in true position could be on the order of 5-10m. Funding was provided by the Long Island Sound Mapping Fund administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).

Description: These seafloor bottom photos were collected as part of the Long Island Sound mapping phase 2 project. During three surveys in 2017 and 2018 aboard the research vessels Pritchard and Seawolf, a GoPro Hero 6 video camera was mounted on the frame of a sediment grab device. The camera was set to record video during the sediment sampling operations. The videos were processed using open-source Shotcut software (www.shotcut.org). The Shotcut video editor was then used to extract frame grab still images after identifying the best image of the seafloor. These still images are in JPEG format. An exiftool script was later used to add the location to each still image file. During the first survey, in 2017, the camera was deployed without external lights and the image was dark below water depths of 8-10m. As result there are some grab stations for which no usable bottom photos exists. For the later surveys, external artificial lights were deployed (Sola video lights, model 3800). These lights allowed video images to be collected in deeper waters. The location of each JPEG image was tagged in the EXIF header with the coordinate information for the corresponding sediment grab station. Location information is based on DGPS navigation using the ship GPS antenna. Lateral offset between the ship GPS antenna and the grab sampling device, and drift of the grab sampling device in the water, have not been corrected. The resulting uncertainty in true position could be on the order of 5-10m.

Description: These final processed two-way time seismic stack sections are part of a seismic investigation of the Lithosphere-Asthenosphere Boundary (LAB) for the African plate in the equatorial Atlantic ocean from 2-75 Ma. The data is cited in Audhkhasi and Singh. (2022). The files are in SEG-Y format and were generated from data acquired in individual sequences starting from 75 Ma (eastern most) to 2 Ma (western most) using a 12-km long Isometrix streamer. The final processed stacked data is split into four SEG-Y files covering 2-27Ma, 27-47Ma, 47-49Ma, and 49-75 Ma respectively. These individual segments were merged to give a ~1400 km continuous line from 2-75 Ma. The file named stack_2_27Ma.segy and the associated image stack_2_27Ma.pdf correspond to Figure S17 of Audhkhasi and Singh (2022) and span the profile ~450 km West-East from point A (2 Ma) to point B (27 Ma) as shown in Figure 1 of Audhkhasi and Singh (2022). The file named stack_27_47Ma.segy and the associated image stack_27_47Ma.pdf correspond to Figure S18 of Audhkhasi and Singh (2022) and span the profile ~450 km West-East from point B (27 Ma) to point C (47 Ma). The file named stack_47_49Ma.segy spans the profile ~100 km North-South from point C (47 Ma) to point D (49 Ma), and the file named stack_49_75Ma.segy spans the profile ~400 km West-East from point D (49 Ma) to point E (75 Ma). The files stack_47_49Ma.segy and stack_49_75Ma.segy have been merged into a single image stack_47_75Ma.pdf, with the turning point of the ship, point D (49 Ma), marked by a vertical black line. The combined files also correspond to Figure S19 of Audhkhasi and Singh (2022). Figure 2 of main article of Audhkhasi and Singh, 2022, has all the files displayed as a single image whereas the supplementary information displays them individually. Processing of the MCS data focused on deeper Earth reflections, particularly the Lithosphere-Asthenosphere Boundary (LAB), and is described in the Materials and Methods and the supplementary figures S3-S15 of Audhkhasi and Singh (2022). Final processed data files (SEG-Y format) in two-way time are made available here along with their associated images. This study was carried out from March-April 2015 and is funded by the ERC Advance Grant agreement No. 339442 TransAtlanticILAB. DOI: 10.26022/IEDA/329809

Description: These processed bathymetry grids were generated from single-beam sonar data collected in 2003-2007 as a part of ecological surveys carried out by the University of Bologna, Italy. The bathymetry data was acquired using a Lowrance HDS sonar operating at 200 kHz coupled with a WAAS-enabled D-GPS for navigation, and was processed by means of the kriging interpolation method using Surfer Golden Software. In most cases, the XY grid spacing was set at 0.5 m, but, in some cases according to areal coverage of data, was set to finer or coarser spacings: 1 m for TC2, Term14, TM1, TM4; 2 m for P208; and, 0.1 m for TSO. Depth values were tide-corrected and referred to the Mean Lower Low Water (MLLW) based on astronomical tide prediction (calculated by WXTide32 software using harmonic data for the nearest available station, i.e. Chioggia or Malamocco). The grid projection is in WGS84 / UTM Zone 33N (EPSG:32633). These bathymetry grids are provided in ESRI ASCII grid format and correspond to the annotated GeoTIFF images in the related data set.

Description: This data set contains a gas hydrate assessment of 48 petroleum industry wells in the Barents and Norwegian Seas. Well log data was obtained from the Norwegian Petroleum Directorate. The gas hydrate stability zone was identified for each well, based on the available gas sample data (or an assumed gas mix), bottom water temperature, bottom hole temperature and hydrostatic pressure. The presence of hydrate is evaluated using resistivity and gamma ray well logs. Some wells had additional data such as P-wave velocity and bulk density which was used when available. A background resistivity was identified or calculated for each hole and resistivity increases above background (0.5 ohm-m and above) were used to identify potential gas hydrate accumulations. The highest resistivities above background were categorized as "A" accumulations, and the lowest were categorized as "D", following the categorization of Majumdar et al., 2017 (Marine and Petroleum Geology). The data file is in tab-separated ASCII text format, with column headers. The data set was generated as part the project called, Carbon storage in widespread low-saturation gas hydrate systems.

Description: This data set consists of logarithmic values of machine-learning-based vertical sediment accumulation rates along the seafloor, globally. The Geospatial Predictive Seafloor Model (GPSM) of the United States Naval Research Laboratory was trained on real-world observations from 89 peer-reviewed sources (n = 1031) to predict marine accumulation rates on a 5-arc-minute map using a k-nearest neighbor algorithm. Original (non-log space values) are in cm/yr. The model and results are described in Restreppo et al. (2020). The data files are in netCDF grid format. The file called prediction.nc contains the predicted sediment accumulation rate in cm/yr. File prediction_sdev.nc is the standard deviation. DOI: 10.26022/IEDA/329769

Description: Seismic refraction and multi-channel seismic reflection surveys were conducted on the northeastern Hawaiian Arch to examine the effect of hotspot volcanism on the seismic structure of the crust and uppermost mantle. The original multi-channel seismic data acquisition and processing was done by JAMSTEC. The pre-stack depth migration processing was carried out at University of Hawaii. The JAMSTEC Kairei system cosnisted of an airgun source volume of 7800 cubic inches, and 444-channel x 12.5 m receivers. The processed PSDM data is stored in SEG-Y format nd is referenced in the Ohira et al., 2018 paper. This data set was generated as part of the project called Oceanic Crustal Structure of the NE Hawaiian Arch, and funding was provided through NSF award OCE13-55468.

Description: Impulsive acoustic events were identified on station AXEC2 by matching waveforms against a suite of 817 waveform templates chosen from isolated arrivals, with high signal-to-noise, that span the eruptive period. Template matching using three-component (HDH, HHZ, and HHN) waveforms returned a set of >37,000 detections (correlation coefficient >0.7). For each detection on AXEC2, the vertical (HHZ) channel waveform was cross-correlated against the other six OOI stations within the caldera to precisely determine the time of the first (sea surface-reflected) and second (sea surface- and seafloor-reflected) arriving phases across the network. Locations were determined using a grid search with a 25 x 25 m spatial resolution. Travel times for both phases were computed assuming a planar sloping seafloor between the source and each receiver with a constant sound velocity of 1485 m/s. The final catalog contains locations for ~22,000 impulsive sounds constrained using at least 7 arriving phases, with an average root mean square error of 0.022 sec. The mean location uncertainty is ~140 m (chi-squared – misfit at 68% confidence). The peak amplitude of each arrival was measured and corrected for geometric spreading loss to estimate the source level (units of dB are 1 micro-Pa @ 1 m). There are additional range-dependent location biases related to anomalies in the water column velocity structure and unmodeled bathymetric effects, which influence the travel times of the sea surface- and seafloor-bouncing arrivals recorded in the caldera. See Le Saout et al. (2020 G-Cubed) for discussion. The data file is in comma-separated ASCII text format and contains the latitude, longitude, acoustic source level, and origin time (year, month, day, hour, minute, second) for acoustic events associated with lava extrusion during the April-May 2015 eruption of Axial Seamount. The data file was generated as part of a project called Research: Earthquake Catalog and Waveform Analysis to Assess the Evolution of Axial Seamount Surrounding the 2015 Eruption. Funding was provided by NSF grant OCE16-35276. DOI: 10.26022/IEDA/329763

Description: These GeoTIFF rasters have the color ramps used in Figure 2 of LeSaout et al. (2020), plus a color ramp that spans the analyzed area. The images are all slope-shaded, hence "slope" in the file names. The depth range, in meters, of the Haxby color ramp used in each of the images is the final part of the filename. These GeoTIFF images were made from a grid of 1-m lateral resolution processed swath bathymetry compiled from MBARI Mapping AUV data acquired on the north rift zone of Axial Seamount with a Reson SeaBat 7125 multibeam sonar system in the summer of 2016 during R/V Rachel Carson cruise RCSN392. The data files are in GeoTIFF grid image format and were generated with several color ramps as indicated by the depth ranges in the file names. The files are in WGS-1984 geographic coordinates, as square cells for use with GIS. Navigation is DVL/USBL, adjusted with MBSystem in post-processing. The AUV navigation adjustment model is consistent with the shapefile of 2015 lava flow boundaries of DOI 10.1594/IEDA/324417 (which is also used in the Le Saout et al. 2020 paper). The files are a subset of the data collected as part of the 2016 Northern Expedition to Axial Seamount. Funding for the work was provided with a grant to MBARI from the David and Lucile Packard Foundation. DOI: 10.26022/IEDA/329694

Description: This data set represents a test of a new type of Lister heat flow and thermal gradient probe developed at SMU. The new probe is called a HyLO Probe ( "Hybrid Lister-Outrigger Probe). The test was performed in 2019 from a dock at Fincastle Lake, Texas, USA. For the test, the 2-meter-long HyLO probe consisted of 4 thermistors spaced 0.25 m apart. The probe was deployed from a dock and achieved full insertion into sediment on the lake floor located approximately 1 m below the dock. This data set consists of the raw temperature data collected during that test. The data show a change in temperature during probe insertion time and the thermistors approaching steady state values over an approximately 30 minute period. These data were used to measure the thermal response time of the thermistors and to calibrate the probe response. Since the data are collected in a shallow lake in winter, the high thermal gradients are an indicator of seasonal changes - it is warmer deeper due to the time it takes for the cold temperatures in the lake water to propagate down 2 meters into the lake bed sediment. The data set was generated as part of the projects called SEKT - Sector collapse kinematics and tsunami implications, and, Field Testing Two New Portable Geothermal Gradient Probe Prototypes. Funding was provided with NSF award OCE19-26729.

Description: This was the first sea trial test of a new type of Lister heat flow and thermal gradient probe developed at SMU. The new probe is called a HyLO Probe ( "Hybrid Lister-Outrigger Probe). This temperature data set consists of the raw temperature data collected with the HyLO probe attached to the bottom 2 meters of a 3-meter-long gravity corer that was deployed from R/V Meteor during the 2019 Lesser Antilles SEKT cruise M154-2. Temperature values were measured at drill site 15-1 using the HyLO probe that consisted of 8 thermistors spaced 0.18 m apart. The data file includes temperatures recorded during transit down to the sea bottom, during stops in the water column for calibration testing, as well as during probe insertion and removal from the seafloor. The data file is in Excel spreadsheet format and contains time and temperature for each of the thermistors. The data set was generated as part of the projects called SEKT - Sector collapse kinematics and tsunami implications, and, Field Testing Two New Portable Geothermal Gradient Probe Prototypes. Funding was provided with NSF award OCE19-26729.

Description: This temperature data set was acquired near the Lesser Antilles island of Montserrat during the 2019 Meteor cruise M154-2. Temperature values were measured at drill site B23702-3 down to 9 mbsf using a thermistor located on the MARUM-MeBo70 sonic logging tool. There are sometimes several temperature measurements at a particular depth because of the pauses whilst the pipe was racked as the sonic tool was pulled out of the formation. The data file is in Excel spreadsheet format and contains depth in meters below seafloor and temperature in degrees C. The data set was generated as part of the project called SEKT - Sector collapse kinematics and tsunami implications. Funding was provided with NSF award OCE19-26729.

Description: This data set consists of processed track line navigation and magnetic field measurements collected by an autonomous underwater vehicle (AUV) in Yellowstone Lake in July 2016 by Ocean Floor Geophysics Inc. (OFG) (https://www.oceanfloorgeophysics.com/). Diurnal corrections to the magnetic data were applied utilizing the Newport (NEW) and Boulder (BOU) geomagnetic observatory records. The regional IGRF magnetic field [Thebault et al., 2015] was removed to produce the anomaly. Navigation was provided by a deployed acoustic transponder network. Data processing of the navigation data included masking of AUV maneuvers and jumps in the data, correction of a residual heading effect and separation of the data acquired at the 15-m height above lake bed from a 7-m height above lake bed. Details of the processing are explained in Bouligand et al., 2020. The data files are in ASCII format with the following columns: longitude, latitude, UTM x (m), UTM y (m), depth(m), height above lake floor (m), magnetic anomaly (nT). The lake surface and AUV magnetic data sets were acquired under National Park Service research permit YELL-2016-SCI-7018.

Description: The processed multibeam bathymetric data were derived from raw multibeam data acquired using a Kongsberg EM 302 multibeam echosounder (MBES). The data set consists of Generic Sensor Format (GSF) swath data files of multibeam bathymetry and backscatter processed using POS-MV navigation. The multibeam surveys were conducted at the Hess Rise and Emperor Seamounts in the North Central Pacific Ocean during R/V Falkor cruise FK190726. The cruise was primarily a biogeographic study using ROV SuBastian and the surveys were designed for ROV dive site selection and multibeam gap filling when time allowed. The data set consists of eight sites that represent places where a dedicated survey with nearly parallel lines or some other pattern took place. The Emperor Seamounts surveyed include Suiko, Yomei, Godaigo, Nintoku, Jingu, Annei, and Koko (from north to south, respectively). Another survey was carried out on Hess Rise. The transit data from Hawaii to Hess Rise are not included in the processed archive because of poor quality. Overpainting of the sonar transducer gondola in the shipyard period prior to this cruise resulted in a reduced swath width, more noise, and dropped beams. The project title is Deep Coral Diversity at Emperor Seamount Chain 2019.

Description: This data set consists of track line navigation and magnetic field measurements collected on Yellowstone Lake in September 2016. The magnetic sensor was an Overhauser scalar magnetometer (Marine Magnetics Explorer sensor) towed at ~15 m behind the USGS boat Alamar with navigation recorded using a GlobalSat USB GPS receiver with a precision of a few meters. The magnetic data was collected at the lake level, at a mean elevation value of 2358 meters above sea level. The data files are in ASCII format with the following columns: longitude, latitude, x (m), y(m), date(YYYY/MM/DD), utc_time(HH:MM:SS), raw magnetic field intensity (nT), magnetic anomaly (nT). The magnetic anomaly was computed after correcting for diurnal variations and removing the regional IGRF [Thebault et al., 2015]. Diurnal corrections were applied utilizing the Newport (NEW) and Boulder (BOU) geomagnetic observatory records. The data set was generated as part of the Hydrothermal Dynamics of Yellowstone Lake (HD-YLAKE) project and was supported by National Science Foundation grant EAR-1516361, U.S Geological Survey Mineral Resource and Volcano Hazard Programs, and benefited from major in-kind support from the U.S. Geological Survey Yellowstone Volcano Observatory. The lake surface and AUV magnetic data sets were acquired under National Park Service research permit YELL-2016-SCI-7018. Maurice Tivey was supported under NSF IPA grant 1557455 to WHOI. During the course of this study, C. Bouligand was a visiting scientist at the U.S. Geological Survey in Menlo Park, California, USA and benefited from a delegation to Centre National de la Recherche Scientifique (CNRS) and received funding from CNRS-INSU program SYSTER.

Description: This processed bathymetric grid was generated from multibeam sonar data collected with a Reson SeaBat 8160 echo-sounder system in 2003 on R/V Arquipelago (investigators Neil Mitchell and Fernando Tempera). The echo-sounder was attached to a temporary mount under the bow of the vessel. The processed bathymetry data is gridded at 100m resolution and the data file is in GMT-compatible netCDF grid format. The data exhibited some cross-track corrugations due to a non-rigid mounting of the transducers but this effect is reduced at the 100m grid spacing. DOI: 10.26022/IEDA/329653

Description: This 2002 Melville cruise, which collected 4-channel MCS data, was part of a multidisciplinary investigation of the thermal state of the subducting lithosphere offshore of the Costa Rica margin. Funded by the U.S. NSF (grants OCE00-01892, OCE00-01941, and OCE00-02031). Its companion cruise, Ticoflux I, was on board the R/V Ewing in 2001. The goals were to determine the comparative thermal state of the subducting lithosphere in these regions, the associated heat and fluid fluxes responsible for the subducting slab thermal states, and how these variables affect subduction zone processes, including chemical flux rates. The data were later reprocessed by Jared Kluesner such that the shot spacing and the CDP (or CMP) spacing (half of channel spacing) is forced to be the same (~30 m), resulting in 4 fold data (4 traces per CDP gather). See vanc02mv.README.Kluesner for details. DOI: 10.1594/IEDA/500153

Description: Funded by the USGS Earthquake Hazards Program USGS-G16AP00150 and NSF (grant NSF-GLD-1638434), this 2016 R/V Alaskan Gyre survey (also known as USGS field activity 2016-654-FA) was a joint effort between the U.S. Geological Survey, the University of Texas Institute for Geophysics, and Texas A and M University. The survey collected 24-channel seismic data and multibeam data in Icy Bay and Taan Fjord, Alaska. The primary goal was to map and characterize offshore fault structures in Icy Bay associated with the Yakutat/North America deformation front. Secondary scientific objectives included characterizing the 2015 Taan landslide failure and modeling the resultant tsunami, mapping Icy Bay glacial deposits, examining tectonic controls on Taan Fjord, researching the geomorphology and slope processes in Taan Fjord, and identifying paleohazards (MTDs, paleoseismic events, etc.) within the region.

Description: This project collected high resolution seismic data in support of a funded NSF proposal: Global and Local Controls on Depositional Cyclicity: the Canterbury Basin, New Zealand. Seismic, multibeam, magnetics and gravity data were acquired concurrently. This marine seismic reflection survey was designed to image high-frequency sedimentary sequences and sediment drifts with the goal of examining the interplay of global (eustacy) and local (tectonics, sediment supply rate and ocean currents) controls responsible for continental margin sedimentation and cyclicity. The data were used to develop an IODP proposal, eventually drilled as IODP Expedition 317 in 2009-2010. Funding was provided by NSF grant OCE-9731031. DOI: 10.1594/IEDA/500007

Description: Part of the Galapagos Plume-Ridge Interaction Multidisciplinary Experiment (G-Prime), this MCS-OBS survey characterized in detail the oceanic created along the Galapagos Spreading Center at 91.3W - 95.5W. The objectives of the project were to: (1) determine how the compensation of the Galapagos swell is partitioned between variations in crustal thickness and mangle density by measuring crustal thickness along the swell and the degree of melting inferred from the chemistry of basalts, (2) determine if there is a threshold factor that controls the transition from an axial high to a rift valley, (3) determine how the extent of magmatic differentiation of ridge basalts relates to the presence or absence of a melt lens, and (4) determine why the degree of partial melting appears to be lower near the hotspot.

Description: This data set consists of SCREECH Transect 1 (1MCS) and lines 101, 102, and 103. This ODP site survey on the Newfoundland margin was a joint project, SCREECH (Studies of Continental Rifting and Extension on the Eastern Canadian SHelf), between the University of Wyoming, WHOI, Dalhousie University, and Danish Lithosphere Centre scientists. The Ewing acquired MCS, magnetic, gravity, and multibeam bathymetric data while the Oceanus acquired wide-angle reflection/refraction data via ocean-bottom seismometers/hydrophones (OBS/Hs). This cruise was to provide a critical dataset for testing models of continental rifting, breakup, and initiation of seafloor spreading in a non-volcanic rifted environment. Its objectives were to: 1) characterize the nature of the crust transitional between oceanic and continental crust in the region; 2) provide a comparison with the Iberian margin, thereby allowing testing of models of pure-shear vs. simple-shear during rifting; and 3) determine the amount of igneous material intruded and extruded during rifting, providing comparative data with other volcanic rifted margins, such as the East Greenland margin. Funding was provided by NSF (grants OCE98-19599 and OCE98-19053), Dalhousie University, Geological Survey of Denmark and Greenland, Danish National Research Foundation (Danmarks Grundforskningsfond), and the Natural Sciences and Engineering Council of Canada.

Description: This data set consists of the western part of SCREECH Transect 3 (3MCS1) and lines 104, 305, 401, 402, and 403. This ODP site survey on the Newfoundland margin was a joint project, SCREECH (Studies of Continental Rifting and Extension on the Eastern Canadian SHelf), between the University of Wyoming, WHOI, Dalhousie University, and Danish Lithosphere Centre scientists. The Ewing acquired MCS, magnetic, gravity, and multibeam bathymetric data while the Oceanus acquired wide-angle reflection/refraction data via ocean-bottom seismometers/hydrophones (OBS/Hs). This cruise was to provide a critical dataset for testing models of continental rifting, breakup, and initiation of seafloor spreading in a non-volcanic rifted environment. Its objectives were to: 1) characterize the nature of the crust transitional between oceanic and continental crust in the region; 2) provide a comparison with the Iberian margin, thereby allowing testing of models of pure-shear vs. simple-shear during rifting; and 3) determine the amount of igneous material intruded and extruded during rifting, providing comparative data with other volcanic rifted margins, such as the East Greenland margin. Funding was provided by NSF (grants OCD98-19599 and OCE98-19053), Dalhousie University, Geological Survey of Denmark and Greenland, Danish National Research Foundation (Danmarks Grundforskningsfond), and the Natural Sciences and Engineering Council of Canada.

Description: This R/V Ewing cruise was proposed to obtain two related seismic data sets: 1) 3D image of the hydrate deposits and 2) a study of the P to S converted waves in the hydrate province. The obtained information, when combined with chemical, sedimentological and downhole logging information from Leg 164 would constitute a rare opportunity to establish benchmarck linkages between seismic signature (reflectivity, P-velocity, S-velocity) and amounts and distribution of hydrate and free gas. The data would also provide basic 3D geometries of stratigraphy, structures, hydrate concentration, and gas accumulations over the study area. This 3D seismic survey over the gas-hydrate field on Blake Ridge was planned with the objective to extend information from ODP sites drilled during Leg 164 over a part of the hydrate province. Funded by NSF grant OCE99-10966 and the U.S. Dept of Energy. DOI: 10.1594/IEDA/500090

Description: This MCS cruise surveyed three well-developed smoothly-domed, turtleback shaped exposures (termed megamullions) of deep-crustal plutonic and upper-mantle ultramafic rock that occur on the flanks of the Mid-Atlantic Ridge. The objectives were to establish the upper seismic velocity structure of these megamullions both laterally and vertically, to gain insight into the deep nature of the oceanic crust and upper mantle now exposed in these megamullions, and to gain a better understanding of how and why megamullions form. This survey was to serve as a foundational site survey to Ocean Drilling Program (ODP) proposals 512-Full and 532-Full and addresses several crustal objectives of the ODP Long Range Plan. Funded by NSF grant OCE99-87004. DOI: 10.1594/IEDA/500091

Description: The Exmouth and Cuvier margin system represents one of the best locales to study the differences between wide versus narrow rifts and to define the interplay between strain partitioning, volcanism, segmentation, and the continent-ocean transition. This geophysical investigation of the Exmouth and Cuvier margins was designed to test alternate models for continental margin development, and when these results are integrated with those from other margin studies, will lead to a better overall understanding and appreciation of: the strain partitioning across margins between the brittle upper crust and the ductile lower crust and lithospheric mantle (e.g., the upper plate paradox); the interplay between extensional style (rift architecture), magmatism and detachments; the continent-ocean transition, and the origin of magnetic anomalies observed off the Exmouth and Cuvier margin; the formation of seaward-dipping reflectors along the continent-ocean boundaries and the importance of faults in their formation.

Description: The MARGINS programs in the US and Japan (of NSF and MEXT) funded an integrated seismic study (marine multi-channel seismic reflection, controlled-source wideangle reflection/refraction, and passive recording of local and teleseismic earthquakes) to provide a comprehensive velocity, attenuation, structural and stratigraphic image of the Mariana island-arc system, from the subducting Pacific Plate to the backarc, at 14-20N, 141-149E. The study included two cruises, EW0202 and EW0203. This cruise served as part 1 of the study, concentrating on MCS profiling. Its companion cruise, EW0203, deployed Ocean Bottom Seismographs (OBSs) and shot MCS lines over them. The principal objectives of the study were to understand: 1) velocity and attenuation structure of the mantle, 2) large-scale flow of the mantle wedge, 3) velocity structure of the subducting oceanic crust, 4) seismic stratigraphy and structure of the forearc, arc and remnant arc, 5) the magma chamber below the volcanoes, 6) a possible double seismic zone, and 7) updip an downdip limits of the seismogenic zone.

The principal objectives of the study were to understand: 1) velocity and attenuation structure of the mantle, 2) large-scale flow of the mantle wedge, 3) velocity structure of the subducting oceanic crust, 4) seismic stratigraphy and structure of the forearc, arc and remnant arc, 5) the magma chamber below the volcanoes, 6) a possible double seismic zone, and 7) updip an downdip limits of the seismogenic zone.

Description: Funded through NSF MARGINS, this Gulf of California experiment (PESCADOR: Premiere Experiment, Sea of Cortez, Addressing the Development of Oblique Rifting) involved two ships, the R/V Maurice Ewing and the R/V New Horizon. The Ewing provided the acoustic source and acquired multi-channel seismic data, and the New Horizon tended to 206 deployments of ocean bottom seismometers. The purpose was to delineate the geometries and patterns of crustal extension and rift magmatism along three main conjugate margins across Alarcon, Guaymas and Delfin Basins (to study the south to north seafloor-spreading to non-spreading mode) and a E-W profile along Wagner Basin (to study the low-angle detachment fault at depth). The questions to be addressed included strain partitioning, volumetric and emplacement style of rift magmatism, along-axis differences in extension style and the influence of sedimentation on deformation. This data set consists of real-time stacks made at sea. Funded by NSF grants OCE01-11983, OCE01-12149, OCE01-12058, OCE01-12152, and OCe01-11738. DOI: 10.1594/IEDA/500101

Description: This cruise acquired 16 scarp-parallel MCS profiles and 7 scarp-perpendicular MCS profiles as well as OBS data across the Hess Deep, near the Pacific-Cocos-Nazca triple junction, eastern Pacific Ocean. A companion program, EW0410, took place in October-November 2004 along the Blanco Transform Fault. The primary objective of the cruise was to make a direct link between the geologic and seismic structure of intermediate-spreading oceanic crust. Questions that were to be addressed by the seismic experiments include: 1) Is there a correlation between seismic and geologic structure at the Blanco Transform? 2) Is the seismic structure at the Blanco Transform typical of intermediate-spreading crust? 3) What is the evolution of the shallow velocity structure from zero-age rise-axis crust to the 0.65-1.65 Ma crust in the study areas?Funding was provided by NSF grants OCE-0137286.

Description: Three teams were involved in the active-source seismic field program: 1) A science party aboard the R/V Maurice Ewing (co-chief scientists P. Mann and D. Sawyer) acquired approximately 6000 km of seismic reflection data. 2) A science party aboard the R/V Seward Johnson II (chief scientist G. Christeson, cruise report) deployed and recovered ocean bottom seismometers (OBSs) along 5 transects; the Ewing provided the seismic source for these instruments. 3) A science party in Venezuela and the ABC islands deployed and recovered seismographs along 4 transects and the island arc; the Ewing and 8 land shots provided the seismic source for these instruments. The purpose was to carry out a geologic-geophysical investigation to test hypotheses related to arc-continent collision and accretion, HP/LT rock exhumation and development of folded belts. Funded by NSF grant OCE0003588.

Description: As part of a site survey for a proposed IODP program to drill marine sediments associated with late Cenozoic climate change and tectonic activity along the southern Alaskan margin, the researchers combined efforts with an already funded piston coring and shallow imaging cruise. The purpose was to acquire additional piston cores and high-resolution seismic images at proposed Gulf of Alaska drill sites. The marine seismic data is to be used in sequence stratigraphic correlations and baseline characterization of the proposed IODP drill sites. Funded by NSF grants OCE02-41828, OCE02-42084, OCE03-51043, OCE03-51062, OCE03-51075, OCE03-51089, OCE03-51096, OCE03-51620, and OCE04-55183. DOI: 10.1594/IEDA/500105

Description: The Blanco Transform Seismic cruise acquired marine seismic reflection and refraction data at the Blanco Transform in the Pacific Ocean. A companion program, EW0305, took place in 2003 where fast-spreading oceanic crust is exposed at Hess Deep. The primary objective of the cruise was to make a direct link between the geologic and seismic structure of intermediate-spreading oceanic crust. Questions that were to be addressed by the seismic experiments include: 1) Is there a correlation between seismic and geologic structure at the Blanco Transform? 2) Is the seismic structure at the Blanco Transform typical of intermediate-spreading crust? 3) What is the evolution of the shallow velocity structure from zero-age rise-axis crust to the 0.65-1.65 Ma crust in the study areas? Funding was provided by NSF grants OCE-0137286. DOI: 10.1594/IEDA/500012

Description: The EW0412 expedition was part of NicStrat, a project designed to image Neogene depositional sequences indicative of sea-level change and stratal geometries that may reflect local tectonic history. The primary objectives were 1) to test the hypothesis that the stratigraphic records of eustatic and tectonic processes can be identified and distinguished on high-resolution MCS data from the Sandino forearc basin, on the Pacific margin of Nicaragua; and 2) to evaluate the record of tectonic events in the form of local unconformities and/or tectonically controlled variations in the geometries and stacking patterns of regional eustatic sequences. Funding was provided by NSF grant OCE-0241179. DOI: 10.1594/IEDA/500006

Description: This combined reflection-refraction seismic experiment was a joint project between UTIG, University of Arizona, Imperial College (UK), Cambridge University (UK), UNAM (Mexico), and CICY (Mexico). The goals were: 1) to determine the direction of approach and angle of the Chicxulub impact as modeling has shown that a 15-20 time greater amount of airborne particles are produced by low-angle impacts; 2) to map the deformation (faults and broken rock) recorded in the upper crust near the crater center that may explain the way the surface of the Earth is damaged by large meteor or comet impacts; 3) to image the key features in the northwest portion of the crater to enable better understanding of the Chicxulub impact structure and prepare for possible future sampling to examine the melted and shattered rocks deep within the crater; 4) to model the 3-D collapse of the crater to examine both the deformation and the environmental effects of the impact to better understand how such an impact can cause worldwide mass extinctions. Funded by NSF grants OCE02-21101 and OCE02-20474, the Natural Environment Research Council, UK, and the Universidad Nacional Autonoma de Mexico. DOI: 10.1594/IEDA/500106

Description: This was a joint UT and Lamont-Doherty Earth Observatory program collecting a series of MCS lines in the Bransfield Strait, across the South Shetland Trench and farther south along the Antarctic margin. UTIG was responsible for the Bransfield Strait and South Shetland Trench data. Additional lines collected farther south along the margin were the responsibility of Lamont-Doherty Earth Observatory. The goals were to increase understanding of the following processes: Andean-type orogenesis, continental lithosphere extension in a convergent continental margin setting, ridge crest subduction, and interaction of large- offset fracture zones with convergent margins, including the uplift of subduction complexes. Funded by NSF grants OCE89-17332 and OCE89-16436. DOI: 10.1594/IEDA/500108

Description: This Two-ship Experiment on a Ridge Axis (TERA) provided the first detailed geophysical constraints on the crustal structure along the East Pacific Rise south of the Garrett fracture zone, a major focus of the RIDGE initiative. The R/V Maurice Ewing< and Thomas Washington (TERA01WT) were to collect three types of data: (1) 20 closely-space, single-ship multichannel seismic reflection profiles along the EPR; (2) 25 two-ship expanding spread profiles along and parallel to the rise axis in this same area; and (3) a 700-km-long multichanel seismic reflection profile along the EPR from the Garrett fracture zone to the large overlapping spreading center at 20.5S. The objectives were to use these data to test the spreading rate dependence of magma chamber size; to examine the relationship between crustal magma chambers and along-axis changes in morphology, segmentation and basalt geochemistry; and to resolve better how the first-order seismic structure of oceanic crust, including Moho and seismic layer 3, developed during the first few hundred thousand years after crustal formation.

Description: This was a study of the extensional mechanisms in the Woodlark basin where westward propagation of seafloor spreading is accompanied by active continental extension in the D'Entrecasteaux islands and flanking basins immediately landward of the propagator. The overall objective was to investigate continental breakup and initiation of seafloor spreading in a region where it is presently active. The aims of the project were to determine: (1) whether intra-continental extension is occurring along low-angle detachment faults or normal faults, (2) whether seismogenic faults can be correlated with faults observed in the seismic sections, (3) the whole crustal geometry of structures that bound the core complexed of Goodenough and Fergusson islands, and (4) whether the transition from intra-continental extension through to continental breadup reflect an evolution of extensional mechanisms. Data collection was funded by NSF grant OCE90-12730. Processing of this data set was funded by NSF OCE 0525671. DOI: 10.1594/IEDA/500114

Description: This was a study of the extensional mechanisms in the Woodlark basin where westward propagation of seafloor spreading is accompanied by active continental extension in the D'Entrecasteaux islands and flanking basins immediately landward of the propagator. The overall objective was to investigate continental breakup and initiation of seafloor spreading in a region where it is presently active. The aims of the project were to determine: (1) whether intra-continental extension is occurring along low-angle detachment faults or normal faults, (2) whether seismogenic faults can be correlated with faults observed in the seismic sections, (3) the whole crustal geometry of structures that bound the core complexed of Goodenough and Fergusson islands, and (4) whether the transition from intra-continental extension through to continental breadup reflect an evolution of extensional mechanisms. Data collection was funded by NSF grant OCE90-12730. Processing of this data set was funded by NSF OCE 0525671. DOI: 10.1594/IEDA/500114

Description: The experiment was a collaborative effort between the University of Delaware, LDEO, UTIG, WHOI, Stanford University, and the USGS. The purpose of this multichannel seismic reflection survey of the Aleutian arc and the extensive Alaskina continental shelf was to obtain high-quality data that could be used to image the deep structure of the crust and uppermost mantle which, when combined with the well-mapped onshore geology, should allow the principal investigators to constrain the mechanisms of accretion and magmatism.

Description: Stanford University, in conjunction with the U.S. Geological Survey, and with participation by the Institute of the Lithosphere and the Institute of the Russian Academy of Sciences, and the Geodynamics Research Institute of Texas A and M University, conducted deep seismic investigations of the continental crust beneath the Bering and Chukchi Seas, Alaska, during the month of August, 1994. The data was recorded to two-way travel-times of 15 to 23 seconds, with 50-75 m shot spacing. Two north-south transects were profiled. The eastern transect extended from 58 degrees 50'N, 168 degrees 32'W, well within the continental shelf of the Bering Sea, north of the Pribilof Islands, to just south of the shelf edge north of Barrow, Alaska, at 71 degrees 49'N, 154 degrees 33'W. Ice prevented continuation of the line beyond the shelf edge. The western transect extended from the central Chukchi Sea, well within the shelf at 71 degrees 23'N, 163 degrees 00'W, into the Aleutian basin at 58 degrees 00'N, 178 degrees 30'W, near Navarinsky Canyon. An additional short line crossing over the Beringian margin a second time was recorded near Zemchung Canyon east of the western transect. The profiles cross important strike-slip faults, possible terrane boundaries, two continental margins, and several Cretaceous/Tertiary sedimentary basins (Norton, Hope, Chukchi, and Navarin Basins). Together with the preceding cruise EW9409, the profiles provide a continuous transect across the North American continent, from the Pacific to Arctic Ocean. Most of the multi-channel (MCS) data is of high quality, but bad weather, strong currents, and recording problems sometimes presented difficulties during data acquisition. Gravity, magnetic, and sonobuoy data were also recorded along the profiles. Wide-angle recording was done in conjunction with the seismic profiling, at recording sites located along the central west coast of Alaska and the Chukchi Peninsula, as well as on islands in the Bering Strait and Bering Sea. The purpose was to conduct deep seismic investigations of the continental crust beneath the Bering and Chukchi Seas. Funded by NSF grant OCE93-17087. DOI: 10.1594/IEDA/500121

Description: This cruise collected data in the Venezuelan Basin and over the Beata Ridge. The cruise had multiple purposes. Venezuela Basin: 1) Define the rough/smooth basement boundary better and examine the spatial and temporal relationship between the different crustal types. 2) Ascertain the crustal velocity structure. 3) Determine crustal thickness variations acrooss the rough/smooth boundary. 4) Image Moho, sub B, and Cretaceous to early Tertiary sediment reflectors. 5) Examine the link between the observed magnetic lineations and structural lineations. Beata Ridge: 1) Determine if crustal thickness variations can explain the differential topography between Beata Ridge and the Venezuelan and Columbian Basins. 2) Determine if additional deformation affected the region due to differential plate motion. 3) Ascertain whether the additional deformation and the resulting topography was due to tensional or compressional forces. 4) Address the history of the relative motion of the Caribbean plate and discern whether the azimuthal and deformation data can be better explained by one or two plates for the Caribbean region by determining the deformational history of the Beata Ridge.

Description: TICOSECT (Trans Isthmus Costa Rica Scientific Exploration of a Crustal Transect), a joint German, Costa Rican and UTIG program, collected seismic refraction data and two-channel reflection data. The objective was to investigate the upper plate response to subducting plate morphology and seamounts as subduction zone asperities. The project was a combined onshore-offshore refraction experiment along three transects (Experiments 1, 2 and 3) and an intense 3-D OBS focus in on the shelf just southeast of the Nicoya Peninsula as part of Experiment 2. Experiment 1 across central Nicoya consisted of dip lines 101 and 102 and strike lines 103, 104 and 105. Twenty OBSs or OBHs were deployed here. Onshore a 3.6 km cable was deployed and 30 PDAS-100 seismographs extended up to 140 km from the coast. Experiment 2 just southeast of the Nicoya Peninsula consists of 37 dip lines, 301-237, and 5 strike lines, 238-242. Thirty OBSs or OBHs were deployed with a separation of 5 km by 1 km and 3 additional OBSs were deployed on extended lines. Experiment 3 was just northwest of the Osa Peninsula consisting of dip lines 301 and 302, and two strike lines, 303 and 304. A total of 26 instruments were deployed on this experiment.

Description: This was an ODP site survey (prior to leg 180) to characterize the rift-to-spreading transition in the Woodlark Basin. The purpose was to study the structural and volcanic processes and the dynamics of the upper mantle that are associated with the splitting of continents. The lateral variation from continental rifting to seafloor spreading within the Woodlark Basin makes it an ideal area to investigate the active process of rifting and spreading center propagation into a continent. The results of this study will provide necessary site survey data with which to plan drilling in the Woodlark Basin. Funded by NSF grant OCE92-01691. DOI: 10.1594/IEDA/500140

Description: A U.S.-Japan cooperative program to map crustal and perhaps upper mantle structures in the Solomon Islands convergent zone. Due to a major cable loss on the previous cruise the cable configuration varied between 112 and 128 channels as new sections were repaired or on-loaded (see cruise report). Japanese OBS's were used in this experiment along line SI-1. The primary objective of the MCS study and an independently proposed OBS study by Drs. K. Suyehiro and colleagues at the Ocean Research Institute in Tokyo, Japan, is to test two models for the formation of the Malaita anticlinorium - the deformed wedge of Cretaceous-Cenozoic pelagic limestone, basalt, and clastic rocks that most previous workers agree to be an emergent part of the Ontong Java Plateau. One model predicts tectonic wedging of the Solomon island arc beneath the Ontong Java plateau. A second, alternative model predicts a more familiar oceanic accretionary wedge geometry with northeastward (plateauward) offscraping and thrust imbrication of plateau rocks. Our proposed MCS-OBS study focusing on the Malaita anticlinorium and North Solomon trench will use state-of-the-art data acquisition and processing techniques to address fundamental questions concerning the subduction/accretion/fragmentation of oceanic plateaus at subduction zones and their deformational effects on the overriding island arc-including collision-related arc polarity reversal. Answers to these questions are important for understanding how oceanic plateaus may contribute to growth of continents through time and how subduction zones initiate by polarity reversal.

Description: This cruise was part of a joint US-New Zealand multiphase crustal-scale study of the Southern Alpine orogen across the central South Island of New Zealand, extending out to sea on either side of the island. This joint US-NZ investigation of continental deformation at convergent plate boundaries was known as the South Island GeopHysical Transection (SIGHT) project. MCS and OBS/OBH data were collected on the west (Tasman Sea) side and east (Pacific Ocean) side of South Island. At the end of the cruise OBS/OBH and SCS data were collected off Kakanui Point just south of Timaru as part of the Southern Cross Anisotropy Survey. One of the objectives was to improve understanding of continental deformation at convergent plate boundaries by using marine onshore/offshore seismic techniques to provide a detailed image of the plate boundary from both sides.

Description: This 1997 Ewing expedition to the Mid-Atlantic Ridge, part of the Nobel at the Mid-Atlantic Ridge Seismic Experiment, collected ocean bottom seismic refraction and single-channel seismic data. The purpose was to measure the reflected and refracted arrivals of seismic energy from sections of the mid-ocean ridge spreading center which have known, previously sampled, rock compositions. These data could then be used to identify and map rock types and test existing models for subsurface ridge structure, possibly providing a 3-dimensional map of the structure of a slow-spreading mid-ocean ridge.

Description: The western Nankai 3-D experiment was conducted in 1999 on the R/V Maurice Ewing Legs 7 (EW9907) and 8 (EW9908). This is a collaborative project between UTIG, University of Hawaii, University of California, Santa Cruz, University of Tokyo, Japanese Geological Survey and STA JAMSTEC. The project consists of 81 dip lines ( Line numbers 92 through 172) each 80 km long with a shot spacing of 50 m. The streamer was 240 channels, 6 km long. There are also a few lines outside of the region, lines Nan-1 (the first line shot and has no navigation), 19, 20, 40, 42, and 50. Two 3-D data volumes are available, one a pre-stack time migration and the other a pre-stack depth migration. The goal of the study is to examine changes in physical properties along the thrust as it changes from aseismic to seismic expression. Understanding this transition from compaction and aseismic slip to brittle failure is a major unknown in understanding lithospheric consumption and earthquake dynamics.

Description: The western Nankai 3-D experiment was conducted in 1999 on the R/V Maurice Ewing Legs 7 (EW9907) and 8 (EW9908). This is a collaborative project between UTIG, University of Hawaii, University of California, Santa Cruz, University of Tokyo, Japanese Geological Survey and STA JAMSTEC. The project consists of 81 dip lines ( Line numbers 92 through 172) each 80 km long with a shot spacing of 50 m. The streamer was 240 channels, 6 km long. There are also a few lines outside of the region, lines Nan-1 (the first line shot and has no navigation), 19, 20, 40, 42, and 50. Two 3-D data volumes are available, one a pre-stack time migration and the other a pre-stack depth migration. The goal of the study is to examine changes in physical properties along the thrust as it changes from aseismic to seismic expression. Understanding this transition from compaction and aseismic slip to brittle failure is a major unknown in understanding lithospheric consumption and earthquake dynamics.

Description: This 1999 Ewing cruise offshore Papua New Guinea, collecting MCS and OBS/OBH data, involved researchers from the University of Hawaii (UH), Lamont-Doherty Earth Observatory (LDEO), and the University of California, Santa Cruz (UCSC). The first part of the cruise was an ODP site survey to characterize in detail the low-angle fault at the rift-to-spreading transition in the Woodlark Basin. UH worked on the MCS and LDEO on the OBS/OBH data. UCSC processed the data from the second part of the cruise which focused on the source region of a 1998 tsunami along the northern continental margin of Papua New Guinea. The purpose of the early part of the cruise was to study the seismicity of an active continental breakup in the western Woodlark Basin. The goal of the second part was to study the internal structure of the tsunami source region. Funded by NSF grants OCE 9730864, OCE 9730824, OCE 9730567, and OCE 9725792. DOI: 10.1594/IEDA/500179

Description: This data set was acquired during an OBS seismic refraction study of the deep crustal structure along the northern margin of the Gulf of Mexico. The fieldwork was conducted from October to December 2010 with M/V Iron Cat operated by Reservoir Geophysical under cruise ID IC1010, and chief scientists were Harm Van Avendonk and Gail Christeson. Four long-offset seismic refraction lines on the northern (U.S.) margin were collected. Airguns fired from the vessel were recorded on the seafloor by four-component ocean-bottom seismometers that had been supplied by the University of Texas Institute for Geophysics in Austin (UTIG) and by Geopro GmbH, Hamburg. The four seismic refraction lines all cross the margin from the shallow water near the coast to the deep water near the U.S.A.-Mexico maritime border. The data files are in SEG-Y format and were generated as part of the GUlf of Mexico Basin Opening (GUMBO) project. DOI: 10.26022/IEDA/328330

Description: Party of a study to explore incised valley fill from three Gulf of Mexico bays, specifically Mobile Bay, Galveston Bay, and Corpus Christi Bay, this R/V Jenny survey collected high-resolution CHIRP data in eastern Mississippi Sound, Alabama during the summer of 2002. Two companion cruises, JN0306 and JN0406, collected CHIRP data in eastern Mississippi Sound in the summers of 2003 and 2004. The goal was to use the data to identify flooding surfaces and help quantify coastal response to forcing mechanisms. This will help test the hypothesis that variations in the rate of coastal subsidence and river discharge were not the cause of the observed coastal backstepping events.

Description: Kingston, Jamaica, the capital of the Caribbean island nation of Jamaica, is prone to infrequent but devastating earthquakes and tsunamis, yet the locations of the faults responsible for generating these geohazards are poorly known. This project used state of the art Chirp (3.5khz) submarine seismic imaging and sediment coring techniques to map active faults and recently active submarine slumps in and around Kingston Harbor.

Description: This 2008 R/V Koca Piri Reis survey of the Marmara Sea was a joint expedition between US and Turkish scientists, collecting over 2649 km of MCS reflection and 3.5 kHz Chirp data for the Turkish-American Marmara Multichannel Project (TAMAM). In 2010, a companion cruise collected additional data. The primary goal of this project was to acquire a high-resolution seismic dataset that could be used to make stratigraphic correlations within and between subbasins in the Marmara Sea and to image shallow structures. Funded by NSF (grants OCE03-28119, OCE03-27273 and OCE09-29063), the Istanbul Technical University, and the Institute of Marine Science and Technology (Dokuz Eylul Univeristy, Izmir, Turkey).

Description: The PIs collected high resolution CHIRP data in Lake Cresent by towing an Edgetech SB512i onboard a small catamaran behind a small boat. Located at the foot of the Olympic Mountains in western Washington, Lake Crescent is a deep glacially carved lake occupying portions of two steep-sided fault-controlled valleys. The lake dates to around14 ka, following retreat of the Juan de Fuca lobe of the Cordilleran ice sheet to the east. The depth of the lake is ~190 m deep. The goal of this project was to improve understanding of the terrestrial upland response to great subduction or other large earthquakes on the Cascadia margin of North America. Funded by NSF grant EAR-1226064. DOI: 10.1594/IEDA/500067

Description: Funded by a Rice University consortium of petroleum companies, this 1990 R/V Lone Star survey used a uniboom seismic source to collect SCS data from Galveston Island to Matagorda Island on the east Texas continental shelf. The objective was to study the effects of global sea-level changes on fluvial-deltaic systems. Data archiving funded by the U.S. Bureau of Ocean Energy Management (BOEM). Navigation for the shot data was obtained by digitizing fix points from a location map from Abdulah, 1995. Start/stop of the SEG-Y files was assumed to match start/stop of the digitized navigation. Actual start/end dates of survey are unknown. DOI: 10.1594/IEDA/500171

Description: This 2015 FS Meteor survey collected ocean bottom seismograph data in the Cayman Trough, Caribbean Sea, as part of a joint US-German-UK project. The goal was to investigate the seismic structure of the Mid-Cayman Spreading Center to determine the extent to which magmatism contributes to crustal structure of an ultra-slow oceanic rift segment. The two main ideas to be addressed were (1) Whether the MCSC hosts oceanic core complexes of exhumed crustal or mantle materials, and (2) Whether crustal thickness variations in the MCSC reflect inhibition of magmatism as the spreading-segment ends are approached. Funding for this project was obtained from the U.S. National Science Foundation under grant OCE-1356895 to UT Austin, from the German Research Foundation (DFG), and from the British Natural Environment Research Council (NERC) under grant NE/K011162/1 to Durham University. The wide-angle seismic data were recorded with instruments from UTIG and GEOMAR, as well as NERC's Ocean-Bottom Instrumentation Facility [Minshull et al., 2005]. The seismic data used in this study will be made available at the Academic Seismic Portal at UTIG (www-udc.ig. utexas.edu/sdc), the World Data Center PANGAEA (www.pangaea.de), and the British Oceanographic Data Centre (www.bodc.ac.uk).

Description: This was the first of four expeditions that surveyed the northern Philippine Sea and the area around Taiwan in support of the TAIGER project, a collaborative project between U.S. and Taiwanese scientists. Legs MGL0905, MGL0906, and MGL0908 used the seismic source array on the R/V Langseth to acquire deep-penetration seismic reflection data and to provide seismic source signals to be recorded by ocean bottom seismographs (OBSs) and seismic instruments on land in Taiwan. The OBSs which recorded the seismic signals during these legs were deployed by various Taiwanese ships and operated by Taiwanese groups and an OBS group from Scripps Institution of Oceanography (the U.S. OBS pool). Leg MGL0907 was dedicated to recovering broadband OBSs, previously deployed in May 2008 (cruise MGLN-38MV of the R/V Melville). The main objective was to study the Taiwan orogeny.

Description: This was the fourth of four expeditions that surveyed the northern Philippine Sea and the area around Taiwan in support of the TAIGER project, a collaborative project between U.S. and Taiwanese scientists. Legs MGL0905, MGL0906, and MGL0908 used the seismic source array on the R/V Langseth to acquire deep-penetration seismic reflection data and to provide seismic source signals to be recorded by ocean bottom seismographs (OBSs) and seismic instruments on land in Taiwan. The OBSs which recorded the seismic signals during these legs were deployed by various Taiwanese ships and operated by Taiwanese groups and an OBS group from Scripps Institution of Oceanography (the U.S. OBS pool). Leg MGL0907 was dedicated to recovering broadband OBSs, previously deployed in May 2008 (cruise MGLN-38MV of the R/V Melville). Its main goals were to acquire OBS data along the primary TAIGER transects T1 and T2 south of Taiwan and to acquire MCS, OBS, and potential field data across the poorly-surveyed northwestern portion of the Philippine Sea tectonic plate. 91 OBS stations were deployed during this cruise.

Description: This dataset contains the time-migrated MCS data along two ridge-to-trench transects across the Juan de Fuca (JdF) plate, from Endeavour Ridge to offshore Washington state and from Axial Volcano to offshore Oregon state, and one 400 km-long trench-parallel transect extending from 44.3N to 47.8N acquired during the 2012 R/V Langseth survey. The seismic reflection images of the two ridge-to-trench transects reveal the crustal structure of the JdF plate, distribution and extent of faults across the plate interior as the crust ages and near the deformation front in response to subduction bending, and a series of distinctive, ridgeward-dipping (20-40 degrees) lower crustal reflections in ~6-8 Ma crust along both transects. The trench-parallel transect characterize the along-strike structural variations of the sediment section and the JdF plate prior to subduction, in particular the structures associated with propagator wakes, a seamount, and four major strike-slip faults.

Description: Part of the Eastern North America Community Seismic Experiment (ENAM), broadband ocean bottom seismometers (BBOBS) were deployed and recovered during R/V Endeavor cruises EN537 and EN544. This experiment augments the Earthscope Transportable Array (TA) with 30 broadband ocean bottom seismometers (OBS) spanning a 400 x 500 km area offshore North Carolina, with three addition onshore broadband stations on the Outer Banks to span the gap between the TA and the OBS network. The seismometers recorded the airgun shots from the 2014 R/V Langseth expedition (MGL1408) as it collected MCS data off North Carolina and Virginia while the R/V Endeavor (EN546) collected OBS data. The goal was to collect data to image geological structures beneath the seafloor to learn about the evolution of continental margins and their geohazards. Funding was provided by NSF grants OCE13-47498, OCE13-48454, OCE13-48124, OCE13-48342, OCE13-48228, and OCE13-47310. Notes: Only the geophone part (not hydrophone) of the data were archived. Data from BBOBS station B01 were not archived. The data in this dataset are in conventional SEG-Y format. All of the ENAM seismic data that has been archived as SEED at the IRIS DMC has been assigned a separate DOI and can be accessed via the landing page, http://www.fdsn.org/networks/detail/YO_2014/ .

Description: This 2008 cruise on the M/V Strong, a collaborative effort between the University of Memphis and University of Texas at Austin, collected high-resolution seismic reflection data and CHIRP data along the Mississippi River, from Helena, Arkansas, to Caruthersville, Missouri. It was followed by two more field seasons in 2010 and 2011. It has been proposed that the seismicity in the New Madrid seismic zone is either 1) episodic; 2) very young (at least in its present incarnation); or 3) migrates throughout a broad region at the continental or regional scale. The purpose of the seismic acquisition was to illuminate the shallow section and provide images of the Mississippi river sediments and of the suspected faults concealed under the subdued topography, providing detailed information on the partitioning of the deformation among key structures beyond the limit of the New Madrid seismic zone that would enable the PIs to test the various hypotheses concerning the zone. Funded by NSF grant 0738855. DOI: 10.1594/IEDA/500060

Description: These seismic shot navigation files accompany the processed 2-D multi-channel seismic reflection data profiles from the Lake Malawi (Nyasa) Rift (Malawi, Tanzania, Mozambique) as part of the PROBE project (Proto-Rifts and Oceanic Basin Evolution) in 1986-1987. The shot navigation files are in ASCII format and contain coordinates in UTM meters, multiplied by a factor a 100 (UTM zone 36-S). Navigation for the Malawi PROBE survey was by transit satellite, radar, automatic speed log and deduced reckoning. Navigational accuracy ranges from <100 m to several km in places. Every line is controlled by a minimum of two fixes and a 40-80 km line is controlled by 5-8 good fixes. Chief Scientist was Bruce R. Rosendahl. Funding for data collection and processing was from multiple 1980s-era oil and gas companies. DOI: 10.26022/IEDA/327534

Description: This data set is a collection of 10 time-processed structural-dip profiles acquired along the length of the Lake Malawi (Nyasa) Rift (Malawi, Tanzania, Mozambique) as part of the PROBE project (Proto-Rifts and Oceanic Basin Evolution). The data files are in SEG-Y format, 6 seconds two-way travel time record length, 4 ms sample rate. Profiles are generally oriented east-west across multiple rift segments. Data were acquired aboard R/V Nyanja, a 36-foot-long dedicated geophysical vessel transportable by cargo aircraft. Source was a single 140 cubic inch EERI airgun, or 3x40 cubic inch array of GSI sleeve guns. Streamer was a GECO custom-built 960 m active-length cable comprising 48 groups (20 m group interval); lead-in cable length varied from 250-440 m. Streamer depth was nominally 10 m and controlled a buoy suspension system. Fold coverage was nominally 24-fold. Acquisition was via Texas Instruments DFS-V, at 2 ms sample rate. Navigation was by transit satellite, radar, automatic speed log and deduced reckoning. Processed navigational data are embedded in SEG-Y trace headers. Navigational accuracy ranges from <100 m to several km in places. Every line is controlled by a minimum of two fixes and a 40-80 km line is controlled by 5-8 good fixes. Chief Scientist was Bruce R. Rosendahl. Data were recovered from 9-track tape and archived on modern media under the supervision of Christopher A. Scholz, Syracuse University. Legacy time processing at Duke University was completed with Digicon DISCO 50 software on a DEC VAX 11/750 computer, applying the following workflow: Demultiplexing, Resample, Geometry Definition, Trace Edit, Sort, Deconvolution, Filter, Velocity Analysis, Stacking, Mute, Migration, Display. Deconvolution is a predictive gap deconvolution, occasionally spiking deconvolution is used. Filtering was variable, typically a bandpass filter with a Hanning taper was employed with typical cutoffs of 6-10 Hz at the low end, and 50-55 Hz at the upper end. Some lines received time-variant filtering and occasionally notch filters were used. Select lines were subjected to a post-stack finite difference time migration routine. Funding for data collection and processing was from multiple 1980s-era oil and gas companies. DOI: 10.26022/IEDA/327533

Description: In this active-source experiment at the Santorini-Amorgos Tectonic Zone, multi-channel seismic reflection data was collected during Poseidon cruise POS338 in 2006 (chief scientist Prof. Dr. Christian Hübscher, University of Hamburg). The airgun seismic source was a single G.I. gun that was used in true G.I. mode (Injector volume: 45 cubic inches; Generator volume: 105 cubic inches) producing a signal of 100 Hz main frequency. The seismic data was recorded with a 24-channel streamer of 600 m length (25 m channel spacing), and stored in SEG-Y format. The processed data files presented here are for seismic line 11 which is discussed in the Preine et al. (2020) paper. These SEG-Y data files allow the reconstruction of each step described in that paper. A short description of each file is included on the data download page and in the accompanying File Description document. Preine et al. (2020) use the faint diffracted wavefield contained in the data to calculate a depth-velocity model for depth migration. Their method works by first modelling the reflected wavefield and then subtracting it from the input-data in the zero-offset domain. The resulting Diffraction-Only section is used to (i) focus the diffractions and derive so-called diffraction-images and to (ii) calculate wavefront attributes and to perform wavefront tomography in order to arrive at a depth-velocity model. This model is manually refined in order to arrive at focused diffractions and is then used for FD depth migration. Seismic line 11 was oriented in a NW-SE direction. The line lies to the northeast of Santorini island and crosses the Santorini-Anafi basin as well as the Amorgos basin. The line is part of a wide collection of reflection seismic profiles acquired during this Poseidon cruise. This seismic survey was funded by the German Research Foundation (Deutsche Forschungsgesellschaft, DFG) with the aim to image the Santorini-Amorgos Tectonic Zone which is well known for its catastrophic volcanic eruptions, earthquakes, and tsunamis.

Description: This data set consists of processed sediment temperature time series from custom thermal probes deployed in and around the Stevenson Island vent field, Yellowstone Lake, Yellowstone National Park, USA. Each probe was 1 m long, 2.5 cm in diameter, and contains seven thermistors with a 10 cm spacing. The thermal probes were deployed with ROV Yogi from R/V Annie which was operated by Global Foundation for Ocean Exploration. Each thermal probe deployment was approximately for one year, from August to August. The data have been processed to convert from resistance to temperature using calibrations for each thermistor. The data files are in ASCII format and give the temperature value at each thermistor. Each data file also includes a header that defines the data columns. The data set was generated as part of the Hydrothermal Dynamics of Yellowstone Lake (HD-YLAKE) project and was supported by National Science Foundation grant EAR15-15283. DOI: 10.26022/IEDA/327524

Description: This integrated acoustic backscatter grid in GeoTIFF format was generated to provide the LIS Mapping and Research Collaborative with a baseline model for benthic habitat classification as part of Phase II of the Long Island Sound (LIS) Benthic Habitat Priority Areas of Interest (AOI) project. The GeoTIFF file in this data set contains acoustic backscatter data combined from different multibeam bathymetry surveys. The original Phase II data sets were surveyed by NOAA Ship Nancy Foster (R-352), NOAA Ship Thomas Jefferson, and the Navigation Response Team (NRT-5) using 400 khz Reson 7125 multibeam sonars from 2003 to 2014. In 2018, the LIS Cable Fund contracted the State University of New York (SUNY) at Stony Brook School of Marine and Atmospheric Sciences (SoMAS) to fill gaps and resurvey areas where multibeam data was not acceptable with the R/V Pritchard using 400 khz Kongsberg dual-swath EM2040C multibeam sonars in coordination with the NOAA National Centers for Coastal Ocean Science (NCCOS) Biogeography Branch and the NOAA Integrated Ocean and Coastal Mapping (IOCM) Program. The multibeam and LiDAR data sets were corrected, calibrated, and integrated into a seamless 32-bit raster using CARIS and ArcGIS. Backscatter data was collected and mosaicked into a raster using Fledermaus Geocoder Toolbox, ArcGIS 10.4, and PCI Geomatica 2018 software. The acoustic backscatter grid is in GeoTIFF raster format. Funding was provided by the Long Island Sound Study and by the Connecticut Department of Energy and Environmental Protection (DEEP).

Description: These processed marine magnetic anomaly grids were derived from the processed ASCII magnetic anomaly data files and have been gridded at ~555 m resolution using a minimum-curvature algorithm, and exported as GMT grids. The magnetic surveys were conducted at the Hess Rise and Emperor Seamounts in the North Central Pacific Ocean during R/V Falkor cruise FK190726 (chief scientist Les Watling). The cruise was primarily a biogeographic study using ROV SuBastian and the surveys were designed for ROV dive site selection and multibeam gap filling when time allowed. The data set is divided into 10 sites that represent places where the magnetometer was deployed for a dedicated survey with nearly parallel lines or some other pattern. The Emperor Seamounts surveyed include Suiko (3 surveys), Yomei, Nintoku, Jingu, Annei, and Koko (from north to south, respectively). Two surveys were carried out on Hess Rise. The 11th and final file of the data set (file name containing 20190822) is a short test file acquired during the return transit and is not one of the project study sites. The data files are in GMT-compatible netCDF grid format and were generated as part of a project called Deep Coral Diversity at Emperor Seamount Chain 2019. Funding was provided by a grant from Schmidt Ocean Institute (Ship, ROV, gravimeter, magnetometer) to Les Watling, PI, and from NOAA OER grant number NA16OAR0110192 (Science support) to John R. Smith, PI. DOI: 10.26022/IEDA/327356

Description: The bathymetry was mapped with a Simrad EM122 multibeam system (1° x 2° system, 12 kHz swath mapping) in Nov/Dec 2019, and processed for quality control through QIMERA software while onboard the vessel. In addition to tracks between ocean bottom seismometer drop sites associated with the Old ORCA experiment (a US contribution to the PacificArray initiative), this data set contains multibeam swath passes within the field region, and on transits to/from Tahiti, and to/from a rescue at ~30S,153W. Sippican MK-21/PC-based XBT measurements were conducted at least daily to account for varying sound speed throughout the experiment, and processed through Simrad SIS software. The final bathymetric maps and grids were created using MATLAB and GMT. The data files are in ASCII format. The files with file name suffix ".xyz" are in UTM meters (zone 6 S). The files with file name suffix ".laloxyz" include geographic latitude and longitude coordinates in decimal degrees, as well as UTM meters. The "km1922_all" files contain bathymetry for the entire cruise mapped at 50 m resolution, and the "obs_array" files contain bathymetry for just the OBS array region, at 100 m resolution. The data files were generated as part of a project called Imaging small-scale convection and structure of the mantle in the south Pacific: a US contribution to international collaboration PacificArray, and Seismological Components of the MELT Experiment on the Southern East Pacific Rise. Funding was provided by NSF awards OCE16-58491, OCE16-58214 and OCE94-02375. DOI: 10.1594/IEDA/327343

Description: This processed towfish navigation data set was collected in August 2018 onboard R/V Trident as part of the Trinity River Paleovalley Project (TRiPP). As the sub-bottom data was acquired, the position of the vessel was continuously determined by a differential GPS system with an antenna mounted at the stern of the ship, near the tow point. A layback correction for the ~5 m offset between the towfish and the D-GPS antenna has been applied to these navigation files. The navigation data files are in ASCII comma-separated format. Funding for the project was provided by the U.S. Department of the Interior, Bureau of Ocean Energy Management, under Agreement Number M16AC00020. DOI: 10.1594/IEDA/326947

Description: This data set is a collection of 12 time-processed dip profiles acquired along the length of the Lake Tanganyika Rift (Tanzania, Democratic Republic of the Congo, Burundi) as part of the PROBE project (Proto-Rifts and Oceanic Basin Evolution). The data files are in SEG-Y format, 6 seconds two-way travel time record length, 4 ms sample rate. Profiles are generally oriented east-west across multiple rift segments. Data were acquired aboard R/V Nyanja, a 32 feet dedicated geophysical vessel transportable by cargo aircraft. Source was a single 140 cubic inch EERI airgun. Streamer was a GECO custom-built 960 m active-length cable comprising 48 groups (20 m group interval); lead-in cable length varied from 250-440 m. Streamer depth was nominally 10 m and controlled a buoy suspension system. Fold coverage was nominally 24-fold. Acquisition was via a Texas Instruments DFS-V, at 2 ms sample rate. Navigation was by transit satellite, radar, automatic speed log and deduced reckoning. Processed navigational data are embedded in SEG-Y trace headers. Navigational accuracy ranges from <100 m to several km in places. Every line is controlled by a minimum of two fixes and a 40-80 km line is controlled by 5-8 good fixes. Chief Scientist was Bruce R. Rosendahl. Data were recovered from 9-track tape and archived on modern media under the supervision of Christopher A. Scholz, Syracuse University. Legacy time processing at Duke University was completed with Digicon DISCO 50 software on a DEC VAX 11/750 computer, applying the following workflow: Demultiplexing, Resample, Geometry Definition, Trace Edit, Sort, Deconvolution, Filter, Velocity Analysis, Stacking, Mute, Migration, Display. Deconvolution is a predictive gap deconvolution, occasionally spiking deconvolution is used. Filtering was variable, typically a bandpass filter with a Hanning taper was employed with typical cutoffs of 6-10 Hz at the low end, and 50-55 Hz at the upper end. Some lines received time-variant filtering and occasionally notch filters were used. All dip lines were subjected to a post-stack finite difference time migration routine. Funding for data collection and processing was from multiple 1980s-era oil and gas companies. DOI: 10.1594/IEDA/326822

Description: The data set contains 7 ASCII files and one ASCII README for a 1-D elastic model and uncertainties beneath the NoMelt array in the central Pacific Ocean. The data files contain the 1-D model of transversely isotropic structure (Vsv, Vsh, Vpv, Vph, eta) and azimuthal anisotropy (Gc, Gs, Bc, Bs, Hc, Hs, Ec, Es) and associated confidence bounds beneath the NoMelt array obtained from inversion of 5–150 s Rayleigh and 5–7.5 s Love waves. The most well-constrained parameters in the model are Vsv, Gc, Gs to 300 km depth and Vsh, Ec, Es to 40 km depth. The remaining parameters are obtained through a priori scaling, as described in Russell et al. (2019). More details are given in the included README file. The radial knots in the azimuthal anisotropy files (NoMelt_ANISO_med.csv, NoMelt_ANISO_l95.csv, NoMelt_ANISO_u95.csv, NoMelt_ANISO_l68.csv, and NoMelt_ANISO_u68.csv) are at the mid-points of the knots in the transversely isotropic file (NoMelt_TI.csv). Although Q was not solved, a generic estimate of oceanic Q is included (NoMelt_Q.csv) only for the purposes of estimating physical dispersion corrections to phase velocity to facilitate reproducibility of Russell et al. (2019). The data files and README are in ASCII format and were generated as part of a project funded under NSF awards OCE-0928270, OCE-1538229, EAR-1361487, and DGE-16-44869. The SIO ocean-bottom seismometers used for the study were deployed in 2011 on Langseth cruise MGL1115 and recovered one year later during Melville cruise MV1218. DOI: 10.1594/IEDA/326504

Description: This data set includes the tied, raw gravity measurements and free-air gravity anomaly values collected using a LaCoste and Romberg model G type gravimeter during a 2012 survey of Santa Cruz Island and a 2016 survey of San Cristobal Island. Gravity measurements from the Santa Cruz survey were tied to a previous measurement at the Charles Darwin Station dock in Puerto Ayora (Ryland, 1971) and for the Santa Cristobal survey to a US Navy tie on a concrete pier in Baltra, Santa Cruz (0° 26' 3'' S, 90° 17' 1'' W). Latitude, longitude, and elevation were collected at each measurement location using a Trimble R7 GPS system. The raw gravity measurements were reduced to a Free Air Anomaly (FAA) by removing instrument drift (~0.01 mGal/day), the effect of elevation above sea level, and the WGS-84 reference ellipsoid. The data file is in ASCII format and was generated as part of the projects called Interdisciplinary Studies of the Galapagos Earth System, and Next Generation Imaging of Magmatic Processes beneath the Juan de Fuca Ridge using MCS data. Funding was provided by NSF awards OCE13-47731 and EAR11-45271. DOI: 10.1594/IEDA/326493

Description: This data set is a time-processed 3-D multi-channel seismic data volume for the East Pacific Rise 9°42'-9°57'N. It is in SEG-Y format and extends for about 27.5 km (along-axis) by 18 km (across-axis) and from 0 to 6.5 seconds two-way travel time on the vertical axis. Seismic reflection events imaged in 3-D by this volume are the seafloor, the axial magma lens, off-axis magma lenses, and the oceanic Moho. The volume was built from multi-channel seismic lines acquired across the East Pacific Rise crest between 9°42'-9°57'N during the MGL0812 seismic survey on R/V Langseth in 2008 (chief scientists: J.C. Mutter, S.M. Carbotte, J.P. Canales, M.R. Nedimovic). A time processing sequence was applied, which includes 3-D geometry definition, spherical divergence correction, filtering, resampling to 4 ms, trace editing, flexible binning, preparation of a 3-D stacking velocity model (for seafloor, magma lens events and Moho; this processing sequence does not include the layer 2A event), normal move-out correction, stacking, post-stack signal enhancement (noise attenuation, predictive deconvolution), cross-line interpolation (from 6.25 x 37.5m bin size to 6.25 x 18.75m bin size), muting of first seafloor multiple, and 3-D Kirchhoff post-stack time migration (see separate file for processing details).

Description: Location of magnetic polarity block boundaries and distances measured along plate tectonic flow lines in 154 ship tracks. File names are, e.g., "CAPANT-84000411_CAP_a.bmdisttrack.txt" where "CAPANT" denotes the plate boundary, "84000411" is the cruise identifier, "CAP" denotes the ridge flank, and "a" is a character distinguishing different track segments from the same cruise (additional track segments would be denoted with characters "b", "c", etc.). Each record in the data file lists a magnetic polarity block boundary (e.g., 'C13ny’), latitude and longitude of the boundary in the original track and on the track projected on a plate tectonic flow line, and distance to the boundary on the projected track. Specifically, each ship track file contains the following columns: (1) Boundary: Magnetic polarity block boundary, e.g., C13ny (young end of anomaly 13 normal block). (2) Long.: Longitude of block boundary on original track (decimal degrees). (3) Lat.: Latitude of block boundary on original track (decimal degrees). (4) Proj.long.: Longitude of block boundary on track projected on a flow line (decimal degrees). (5) Proj.lat.: Latitude of block boundary on track projected on a flow line (decimal degrees). (6) Proj.dist.: Distance to block boundary on track projected on a flow line (km). (7) Proj.dist.st.dev.: Standard deviation of distance to block boundary (km). The data files are in ASCII format and were generated as part of a project called A global survey of marine magnetic anomalies to constrain the Late Cretaceous-Eocene time scale.

Description: These processed free-air gravity anomaly data files were derived from raw gravity data acquired using a portable Lacoste & Romberg gravimeter with an Ultrasys control system. The data set consists of CSV line-data files of gravity anomalies at a 1 Hz sample rate and processed using POS-MV navigation. Each file contains column headers. The gravity values can be re-calculated or filtered using different techniques: A corresponding PDF document file contains the equations to re-calculate gravity. The gravity surveys were conducted at the Hess Rise and Emperor Seamounts in the North Central Pacific Ocean during R/V Falkor cruise FK190726. The cruise was primarily a biogeographic study using ROV SuBastian and the surveys were designed for ROV dive site selection and multibeam gap filling when time allowed. The data set is divided into 10 sites (places where a dedicated survey with nearly parallel lines was conducted) and 8 transits between these sites. Transits are sequentially ordered starting from Honolulu, Hawai‘i to Hess Rise and on to the Emperor Seamounts with a return transit to Honolulu along the northern side of the Northwest Hawaiian Ridge. The Emperor Seamounts surveyed include Suiko, Yomei, Godaigo, Nintoku, Jingu, Annei, and Koko (from north to south, respectively). The data files are in ASCII format and were generated as part of a project called Deep Coral Diversity at Emperor Seamount Chain 2019. Funding was provided by the Schmidt Ocean Institute (Ship, ROV, gravimeter) to Les Watling, PI, and from NOAA OER grant number NA16OAR0110192 (Science support) to John R. Smith, PI.

Description: These processed MCS image files are part of a seismic investigation of seafloor, basement and layer 2A for the African plate in the equatorial Atlantic ocean from 0-75 Ma (investigator Satish Singh). The data is cited in Audhkhasi and Singh (2019). The multi-channel seismic data was acquired in individual sequences starting from sequence 1 (eastern most) to sequence 14 (western most) using a 12 km long streamer. Three ridge-orthogonal profiles were acquired, each composed of more than one sequence. The three ridge-orthogonal parts of the profiles have been combined to produce a continuous flow line from 0-75 Ma. Processed data files (SEG-Y format) and their associated images (PNG format) have been made available for the sequences 1, 4, 5, 6, 7, 9, 10, 11, 14. The omitted sequences are either entirely in the turning part of the profile (for instance, sequence 12) or are too small (< 10 km) to provide any substantial information (for instance, sequence 3). The processing steps involve geometry merging, velocity analysis for layer 2A triplication, and top and bottom mute to stack only 2A retrograde energy for super-CMP gathers. These steps are described in supplementary figure S2 of Audhkhasi and Singh (2019). The seafloor, basement and 2A event was picked on the processed data and has been made available as a related data set for three ridge-orthogonal parts of the profile: leg1_age_sf_l2a.mat, leg2_age_sf_bs_l2a.mat and leg3_age_sf_bs_l2a.mat.

These steps are described in supplementary figure S2 of Audhkhasi and Singh (2019). The seafloor, basement and 2A event was picked on the processed data and has been made available as a related data set for three ridge-orthogonal parts of the profile: leg1_age_sf_l2a.mat, leg2_age_sf_bs_l2a.mat and leg3_age_sf_bs_l2a.mat. The picks were used for plotting figure 4 of Audhkhasi and Singh (2019). This study was carried out from March-April 2015 and is funded by the ERC Advance Grant agreement No. 339442 TransAtlanticILAB. DOI: 10.1594/IEDA/326175

Description: This multibeam gridded bathymetry data set was collected using an EM300 swath sonar system during R/V Thomas Thompson cruise TN214. The primary goal of the cruise was to deploy 40 ocean bottom seismometers (OBS) and 7 seafloor geodesy tripods at the Quebrada/Discovery/Gofar (QDG) transform fault system on the equatorial East Pacific Rise. There were three target survey areas for high-resolution seafloor mapping: the Discovery and Quebrada transform faults, and a potentially rotating nano-plate just north of the Discovery transform fault. The surveys were typically carried out at a survey speed of 5 knots, with a fixed swath width of 4 km (135 beams/ping). The bathymetry was processed using the CARIS Hips&Sips software. The data file is in GMT-compatible netCDF grid format, gridded at a resolution of 75m with no interpolation to fill data gaps, WGS-84. The gridded TN214 bathymetry data is used in the Wolfson-Schwehr et al., 2014 paper. This project was funded by NSF Award 0242117, with Principal Investigators Jeffery McGuire, John Collins, and Robert Detrick. DOI: 10.1594/IEDA/324928

Description: Second version of a bathymetric map of the Baker-Martinez fjord complex (Chile, 48°S) constructed from multiple data sets: multibeam echosounder data of Baker channel (Harada et al., 2008) and of Steffen fjord and Baker river delta (Vandekerkhove et al.), single beam echosounder data of Martinez channel (R/V Sur-Austral 2015/2016) and Jorge Montt fjord (Rivera et al., 2012, Moffat, 2014 and additional data from C. Moffat) and individual bathymetry points (digitized using Global Mapper software) from two SHOA nautical charts (SHOA, 2001, 2008). The heterogeneous data with distinct spatial resolution was gridded using the kriging method (3.6 arc-second resolution) in Surfer from Golden Software. Compared to the first version (Piret et al., 2017), this new version features improved bathymetry for the Martinez Channel. We intend to update this map when new data sets become available.

Description: This Total Magnetic Intensity (TMI) data set covers the region of southern Malawi between longitudes 34 45 E – 36 00 E and latitudes 14 45 S and 16 15 S. This processed data set is part of aeromagnetic data acquired in 2013 by the Government of Malawi through the Ministry of Mines – Geological Survey Department. The data set was collected with NE-SW oriented flight lines, flight line spacing of 250 m, tie lines spacing of 2.5 km, and an average terrain clearance of 60 m. The data were reduced to pole (RTP); hence the gridded data archived in this data portal is RTP TMI. The data is used in a study of the lithospheric structure beneath the Cretaceous Chilwa Alkaline Province (CAP) in southern Malawi and northeastern Mozambique. The data set is made available to other geoscientists for the purpose of scientific research only. Full acknowledgement should be given to the Government of Malawi – Ministry of Mines – Geological Survey Department. For addition specification of data acquisition contact the Geological Survey Department at P.O. Box 27, Zomba, Malawi. DOI: 10.1594/IEDA/324860

Description: This data set is a tomographic model of mantle P-wave speeds beneath the Juan de Fuca and Gorda plates offshore of the Pacific northwest. The model conforms to a surface located 1 km beneath the oceanic Moho. Due to the nature of the seismic data used to construct this tomographic image (primarily Pn head waves), P-wave speeds reflect an average over the uppermost ~7 km of the oceanic mantle. The model and results are described in VanderBeek and Toomey (2019). In summary, the model was constructed by inverting 3363 travel-times from 162 local earthquakes recorded by Cascadia Initiative ocean bottom seismometers. Travel-times were inverted using an iterative anisotropic tomography algorithm. The isotropic and anisotropic component of the model is provided as an ASCII file (see header comments in file for file structure). The isotropic component of the model (the P-wave speed) is also provided as a data layer in GeoMapApp. The data set was generated as part of the projects called "Structure and Dynamics of the Lithosphere-Asthenosphere System Beneath the Juan de Fuca Plate" and "Understanding Subduction Systems by Linking Anisotropic Seismic Imaging and Geodynamic Modeling". This work was supported by the National Science Foundation under grants OCE‐1139701, OCE‐1333196, and EAR‐1520694 to the University of Oregon. DOI: 10.1594/IEDA/324858

Description: This data set consists of a tomographic model of the anisotropic P-wave seismic velocity structure of the crust and topmost mantle beneath the seafloor at the Endeavour segment of the Juan de Fuca Ridge. The model was derived from active-source data acquired during the ETOMO 3-D seismic tomography experiment conducted during Langseth cruise MGL0910 in 2009 (chief scientists Doug Toomey, Emilie Hooft, William Wilcock). The model and results are described in Arnoux et al. (2019). A three-dimensional, iterative tomographic technique was used to invert 96,155 Pg refraction, 105,000 PmP reflection, and 12,000 Pn refraction arrival times to constrain isotropic slowness and seismic anisotropy within the crust and topmost mantle, in addition to Moho depth. The data set is in ASCII format and contains longitude, latitude, and P-wave velocity perturbations (dVp) relative to a depth-dependent, off-axis velocity average. The P-wave velocity perturbations are given at depths of 0.6, 1.2, 1.8, 2.4, 3.0, 3.6, 4.2, 5.2, 5.8, and 7.8 km depth below seafloor. All depths are masked in regions of poor ray coverage and poor resolution. This data set was generated as part of the projects called (1) ETOMO: Endeavour Seismic Tomography Experiment and Testing Models of Magmatic and Hydrothermal Segmentation: A 3-D Seismic Tomography Experiment at the Endeavour Ridge and (2) Next-generation 3D imaging of the on- and off-axis mantle and crustal magmatic systems at the Endeavour segment.

Description: Stanford University, in conjunction with the U.S. Geological Survey, and with participation by the Institute of the Lithosphere and the Institute of the Russian Academy of Sciences, and the Geodynamics Research Institute of Texas A and M University, conducted deep seismic investigations of the continental crust beneath the Bering and Chukchi Seas, Alaska, during the month of August, 1994. The data was recorded to two-way travel-times of 15 to 23 seconds, with 50-75 m shot spacing. Two north-south transects were profiled. The eastern transect extended from 58 degrees 50'N, 168 degrees 32'W, well within the continental shelf of the Bering Sea, north of the Pribilof Islands, to just south of the shelf edge north of Barrow, Alaska, at 71 degrees 49'N, 154 degrees 33'W. Ice prevented continuation of the line beyond the shelf edge. The western transect extended from the central Chukchi Sea, well within the shelf at 71 degrees 23'N, 163 degrees 00'W, into the Aleutian basin at 58 degrees 00'N, 178 degrees 30'W, near Navarinsky Canyon. An additional short line crossing over the Beringian margin a second time was recorded near Zemchung Canyon east of the western transect. The profiles cross important strike-slip faults, possible terrane boundaries, two continental margins, and several Cretaceous/Tertiary sedimentary basins (Norton, Hope, Chukchi, and Navarin Basins). Together with the preceding cruise EW9409, the profiles provide a continuous transect across the North American continent, from the Pacific to Arctic Ocean. Most of the multi-channel (MCS) data is of high quality, but bad weather, strong currents, and recording problems sometimes presented difficulties during data acquisition. Gravity, magnetic, and sonobuoy data were also recorded along the profiles. Wide-angle recording was done in conjunction with the seismic profiling, at recording sites located along the central west coast of Alaska and the Chukchi Peninsula, as well as on islands in the Bering Strait and Bering Sea. The purpose was to conduct deep seismic investigations of the continental crust beneath the Bering and Chukchi Seas. Funded by NSF grant OCE93-17087. DOI: 10.1594/IEDA/500121

Description: This cruise was part of a joint US-New Zealand multiphase crustal-scale study of the Southern Alpine orogen across the central South Island of New Zealand, extending out to sea on either side of the island. This joint US-NZ investigation of continental deformation at convergent plate boundaries was known as the South Island GeopHysical Transection (SIGHT) project. MCS and OBS/OBH data were collected on the west (Tasman Sea) side and east (Pacific Ocean) side of South Island. At the end of the cruise OBS/OBH and SCS data were collected off Kakanui Point just south of Timaru as part of the Southern Cross Anisotropy Survey. One of the objectives was to improve understanding of continental deformation at convergent plate boundaries by using marine onshore/offshore seismic techniques to provide a detailed image of the plate boundary from both sides.

Description: As part of a site survey for a proposed IODP program to drill marine sediments associated with late Cenozoic climate change and tectonic activity along the southern Alaskan margin, the researchers combined efforts with an already funded piston coring and shallow imaging cruise. The purpose was to acquire additional piston cores and high-resolution seismic images at proposed Gulf of Alaska drill sites. The marine seismic data is to be used in sequence stratigraphic correlations and baseline characterization of the proposed IODP drill sites.

Description: As part of a site survey for a proposed IODP program to drill marine sediments associated with late Cenozoic climate change and tectonic activity along the southern Alaskan margin, the researchers combined efforts with an already funded piston coring and shallow imaging cruise. The purpose was to acquire additional piston cores and high-resolution seismic images at proposed Gulf of Alaska drill sites. The marine seismic data is to be used in sequence stratigraphic correlations and baseline characterization of the proposed IODP drill sites. Funded by NSF grants OCE02-41828, OCE02-42084, OCE03-51043, OCE03-51062, OCE03-51075, OCE03-51089, OCE03-51096, OCE03-51620, and OCE04-55183. DOI: 10.1594/IEDA/500105

Description: Part of the Galapagos Plume-Ridge Interaction Multidisciplinary Experiment (G-Prime), this MCS-OBS survey characterized in detail the oceanic created along the Galapagos Spreading Center at 91.3W - 95.5W. The objectives of the project were to: (1) determine how the compensation of the Galapagos swell is partitioned between variations in crustal thickness and mangle density by measuring crustal thickness along the swell and the degree of melting inferred from the chemistry of basalts, (2) determine if there is a threshold factor that controls the transition from an axial high to a rift valley, (3) determine how the extent of magmatic differentiation of ridge basalts relates to the presence or absence of a melt lens, and (4) determine why the degree of partial melting appears to be lower near the hotspot. Funded by NSF grants OCE98-18632, OCE98-19117, and OCE98-18886. DOI: 10.1594/IEDA/500089

Description: This data set, presented in Heath et al. (2019), consists of a P-wave tomographic model of Santorini Volcano and the surrounding region including the Christiana and Anydros Basins as well as the Kolumbo Volcanic Field. The model was derived from dense active-source data with airguns fired from the ship to an array of ocean-bottom and land seismometers during the PROTEUS experiment on cruise MGL1521 (chief scientist Emilie Hooft). Using standard isotropic tomographic techniques, the model was created by inverting ~200,000 P-wave travel-times of rays that sampled the upper crust. The data files are in NetCDF format (suitable for importing to GMT scripts), gridded at approximately 100m resolution. The “Vel-*.grd” files consists of lat/lon and dv values, where the latter measures the deviation of seismic velocity from a depth dependent velocity average. We present velocities at depths of 0, 1, 2, and 3 km which are conformal to the bathymetry/topography. Files labeled with “Velwithdws” consist of lat/lon/dv values where regions of poor ray coverage and poor resolution are masked out. This data set was generated as part of the Plumbing Reservoirs Of The Earth Under Santorini (PROTEUS) experiment, with funding provided by NSF grant OCE14-59794 and Leverhulme Grant RPG-2015-363.

Description: This data set comprises an earthquake catalog derived by relocating earthquakes on Axial Seamount from January 2015 through February 2017 using 3-D P-wave and S-wave velocity models obtained from a joint inversion of earthquake P-wave and S-wave arrival times for velocity structure and earthquake locations. The arrival times were obtained from the seismic network on the Ocean Observatories Initiative Cabled Array at Axial Seamount. The study that obtained the catalog is described in Baillard and Wilcock (2019). The catalog is presented in two files, one that includes only hypocenters and one that includes both hypocenters and phase information. Both files are in NonLinLoc format. NonLinLoc is documented in general at http://alomax.free.fr/nlloc/ and the specific format for the catalog files is documented at http://alomax.free.fr/nlloc/soft7.00/formats.html#_location_hypphs_.

Description: These multibeam bathymetry grids were collected in 2015 aboard the R/V Sharp, as part of the Office of Naval Research-sponsored Seabed Characterization Experiment (https://wwwext.arlut.utexas.edu/sbcex/). The rectangular survey region, oriented ~E-W in ~60-80 m water depths, measured ~11 km wide and 30 km long. It included 42 strike (E-W) lines spaced ~250 m apart that were used to form the data grids. Multibeam data were collected using a Reson 7125 instrument operating at 200 kHz, and processed using CARIS software. Differential GPS were used for navigation, and an Applanix POS MV inertial motion unit provided attitude control. Raw bathymetry were corrected for pitch, heave, yaw and roll. Raw bathymetry are also manually edited to remove erroneous echosounder pings, recognizable by large positive or negative anomalies from the norm. Conductivity-temperature-depth (CTD) casts were periodically collected and used to determine water depths from the swath soundings. However, this processing step posed a difficult challenge owing to the rapidly changing water masses in the survey region, which was influenced by eddies from the nearby Gulf Stream; CTD readings were insufficiently sampled both in time and space to adequately characterize the variability of the sound speed profile. Incorrect assumptions about sounds speed profile cause the cross-swath profile to either curve upwards (“smile” artifacts) or downward (“frown” artifacts). These effects can be empirically corrected within CARIS, but result in added uncertainty in the overall depth which are often expressed as mismatch between adjacent swaths. The data files are in NetCDF format (suitable for importing to GMT scripts), gridded at 1m to enhance visualization of small-scale features, which are numerous. Projection is in UTM Zone 19N. To keep file sizes manageable, the data grids are sectioned into eastern, central and western subregions. DOI: 10.1594/IEDA/324799

Description: These water column data files were collected in Monterey Canyon as part of the Monterey Canyon Coordinated Canyon Experiment (CCE). The CCE was set up to measure the passage of sediment gravity flows down Monterey Canyon. A dense array of sensors (more than 50) were deployed for three consecutive six-month periods from October 2015 to April 2017 in Monterey Canyon between 280 and 1850 m water depth. Instruments were mounted on moorings between 10 and 300 m above the seafloor. The data files are in netCDF format and include the following types of data: Optical and acoustic backscatter, transmissivity, conductivity, temperature, pressure, salinity, wave height and current velocity, fluorescence, dissolved oxygen, and altimetry. File names begin with MBCCE, then mooring name, followed by an abbreviation for the sensor, and then the deployment date (yyyymmdd). For more specific information about each data file, download the excel file "CCE Files and Stations" and review the "Science Report" under Documents.

Description: Sediment grain size data from Anderson sediment trap samples collected in Monterey Canyon as part of the Monterey Canyon Coordinated Canyon Experiment (CCE). The CCE was set up to measure the passage of sediment gravity flows down Monterey Canyon. Anderson sediment traps are designed to passively collect particulate material as it settles from the water column into a tube. This effectively provides a record of the sediment and particulate matter passing through the water column. Sediment traps were deployed on moorings for three consecutive six-month periods from October 2015 to April 2017. After recovery these tubes were logged with a multi-sensor core logger and a CT scanner and subsequently extruded, and sampled. The grain size data files are in Excel spreadsheet multi-tab format. File names begin with MBCCE, then mooring name, followed by sediment trap name, height above the bottom, and then the deployment date (yyyymmdd). For more specific information about each data file, download the excel file "CCE Files and Stations" and review the "Science Report" under Documents.

Description: Benthic Event Detectors (BEDs) were placed in Monterey Canyon as part of the Monterey Canyon Coordinated Canyon Experiment (CCE). The CCE was set up to measure the passage of sediment gravity flows down Monterey Canyon. BEDs are "smart boulders" that record time-stamped acceleration, rotation, and ambient pressure data. Each BED device is a 43 cm diameter sphere with 1.8 g/cc density in air, weighing 81.5 Kg in air and 35 Kg in water. The experimental design of the CCE called for having BEDs on the canyon floor at 200, 300 and 400 m water depth. Within logistical constraints, after BEDs moved during sediment flows, these depths were repopulated with newly-deployed BEDs. A total of 11 BEDS and two AMT/BED deployments took place during the CCE. BEDs deployed multiple times are denoted with A, B and C for each deployment. CU indicates a cubic-shaped bed. BED deployment locations are listed under the station Acquisition Information tab. There are two types of data files presented here. The pressure data file, called MBCCE_BED_Depths_Time.xlsx, is an Excel spreadsheet that includes tide-adjusted depth of the BEDs during sediment gravity flows. The rotational data files are Excel spreadsheets that contain the raw quaternion data recorded by the inertial motion unit once the BED started to move due to the arrival of a sediment gravity flow. The four columns in each of the rotational data files are the quaternion components: quaternion component 1 (rotation angle parameter), quaternion component 2 (vector coordinate), quaternion component 3 (vector coordinate), and quaternion component 4 (vector coordinate). BED rotational data retrieved wirelessly from BEDs deployed on the seafloor have a sample resolution of 5 samples per second. The resolution of rotational data from BEDs that were physically recovered is 50 samples per second, except for BED05. Pressure changes were recorded 5 seconds after the initiation of motion. Thus, there is no depth information for the first 5 seconds of rotational motion. The rotational data file names are structured as BED ID_date of event (yyyymmdd)_sampling rate (5 Hz or 50 Hz)_optional (segment of the event or none if full event). For additional information about the BEDs, review the "Science Report" and download the file "CCE BED Deployment Locations" under the Documents tab.

Description: An array of three Sonardyne Acoustic Monitoring Transponders (AMTs) was placed in Monterey Canyon to monitor small scale seafloor movements (creep) as part of the Monterey Canyon Coordinated Canyon Experiment (CCE). The CCE was set up to measure the passage of sediment gravity flows down Monterey Canyon. Each instrument was in place for deployments lasting up to six months beginning in October 2015 and October 2016. One AMT was placed at 300 meters water depth in the canyon axis and the other two on stable benches on the canyon sides. The central AMT, deployed in the axis on a large (800 kg, >2 m tall) frame, also had a BED mounted to the side. Each AMT recorded the acoustic range to the other instruments as well as pitch, roll, temperature, and depth every 45 minutes. The data files are in ASCII comma-separated format. File names begin with MBCCE, then mooring name, followed by the date range of the collected data (yyyymmdd to yyyymmdd).

Description: The processed bathymetric grids were generated from high-resolution, multibeam bathymetric surveys of the Monterey Canyon floor. Two sites were surveyed 6 times each between October 2015 and April 2017 with an MBARI mapping AUV (Autonomous Underwater Vehicle) as part of the Monterey Canyon Coordinated Canyon Experiment (CCE). The CCE was set up to measure the passage of sediment gravity flows down Monterey Canyon and their effect on the bathymetry. Repeat surveys captured changes in bathymetry during the experiment. The AUV carried a Reson 7125 multibeam echo-sounder (vertical precision of 0.15 m and horizontal resolution of 1.0 m). An inertial navigation system combined with a Doppler velocity logger allowed the AUV to fly pre-programmed grids at 3 knots, while maintaining an altitude of 50 m above the seafloor, to obtain a nominal line spacing of 130 m. These data files have been cleaned, and tide corrected. A significant effort was made to co-register all the surveys together at each site (CCE_Shallow and CCE_DEEP) using MBnavadjust, part of MBSystem. The shallow surveys were conducted in water depths between 200-500 m and the deep surveys were in water depths of 1350-1880 m. The data files are in netCDF grid format with horizontal 1 m resolution and are projected into UTM zone 10N. The grid files are compatible with GMT programs and MBSystem. For more information about the grids review the "Science Report" under Documents. Funding for this part of the project was provided to investigators Charles Paull and David Caress by The David and Lucile Packard Foundation. DOI: 10.1594/IEDA/324756

Description: The bathymetry was mapped with an ELAC Seabeam 1050 multibeam system in austral winter 2016. A mounting frame holding two 50 kHz transducers at a 120-degree angle, was installed at the bow of the R/V Sur Austral (COPAS Sur-Austral, Chile). In order to correct for roll, pitch, and heave movements, an Octans Motion Sensor (IXSEA) was placed on the mounting pole above the transducers. CTD measurements were continuously recorded at the water surface (approximately 1 m depth) using a Valeport Modus CTD. To correct for sound velocity changes with depth, a total of 24 vertical CTD profiles were taken with an RBR Maestro, operated at a sampling rate of 6 Hz and vertical speed of 1 m/s. The multibeam data were processed with Caris HIPS and SIPS v9.1, including tide correction based on tide tables at Caleta Tortel (maximum tidal range of 1.9 m). The final bathymetric maps and grids were created using Fledermaus v7 and GMT. The data file is in KMZ format. DOI: 10.1594/IEDA/324734

Description: These gridded data files present tomographic models of P-wave seismic velocity structure of the upper 2-3 km of oceanic crust between the Mid-Atlantic Ridge and the Rio Grande Rise. The models were derived from active-source data acquired during the CREST 2-D seismic experiment conducted during Langseth cruise MGL1601 in 2016 (chief scientists Bobby Reece and Gail Christeson). The models and results are described in Kardell et al. (2019). Using a 2-D constant gradient starting model of crustal velocity, iterative tomographic inversions were performed with traveltime picks of refracted arrivals on more than 2000 shot gathers. Traveltime residuals were inverted for 2-D slowness perturbations, and ray paths and traveltimes were predicted using a shortest-path algorithm. Ray tracing was performed on a 2-D grid constrained by seafloor topogrophy from multi-beam measurements and basement topography picked on migrated seismic images. The data set is in netCDF grd format, which can be used in GMT software. It was generated as part of the CREST project: Crustal Reflectivity Experiment Southern Transect. Funding was provided by NSF grants OCE15-37108 and OCE15-37169. DOI: 10.1594/IEDA/324716

Description: These mask files contain the upper and lower bounds of ray coverage achieved for the tomographic velocity models produced by Kardell et al. (2019). They can be used in GMT to only plot the velocity values constrained by the inversion, while cutting out the lower, unconstrained part of the velocity model. The files contain two columns: the left column gives lateral distance along the velocity model in kilometers; the right column gives depth values, also in kilometers. The first block of values includes the lower bounds of ray coverage and the second block includes the upper bounds. The data set was generated as part of the CREST project: Crustal Reflectivity Experiment Southern Transect (chief scientists Bobby Reece and Gail Christeson). Funding was provided by NSF grants OCE15-37108 and OCE15-37169. DOI: 10.1594/IEDA/324720

Description: This data set consists of travel times for the mantle refraction, Pn, picked from active-source OBS data collected as part of the NoMelt experiment in the central Pacific. The data set is in ASCII format. For each travel time, the shot line number, station location, and shot location are provided. Before picking, the OBS data were filtered with an 8-pole, minimum phase Butterworth filter with corner frequencies of 4 to 15 Hz, and a linear prediction deconvolution was applied using a filter length of 0.2 seconds and a prediction distance of 0.01 seconds. Travel times were then picked by hand on the vertical ground motion components of station gathers. This data set was generated as part of a project called NoMelt: Structure and evolution of the oceanic lithosphere/asthenosphere system. Funding for this project came from NSF grants OCE09-28663, OCE09-27172, and OCE09-28270. DOI: 10.1594/IEDA/324643

Description: This 3-D P-wave and S-wave seismic velocity model was derived from active-source data acquired during the ETOMO 3-D seismic tomography experiment that was conducted during Langseth cruise MGL0910 in 2009 (chief scientists Doug Toomey, Emilie Hooft, William Wilcock). Using a 3-D starting model of crustal velocity from previous tomographic studies of crustal refractions, a joint inversion was performed with Pg and Sg crust refraction arrival times using P-to-S coupling constraints. The model and results are described in Kim et al. (2019). The data file is in ASCII format and contains the following 5 columns: x-local-coordinate (km), y-local-coordinate (km), z-local-coordinate (km), P-wave velocity (km/s), and S-wave velocity (km/s). z is depth below the seafloor. The local coordinate is centered on 47.9826N and -129.0776W and rotated -21N. The data set was generated as part of the projects called ETOMO: Endeavour Seismic Tomography Experiment and, Testing Models of Magmatic and Hydrothermal Segmentation: A 3-D Seismic Tomography Experiment at the Endeavour Ridge.

Description: This earthquake catalog spans 26 July 2011 through 1 September 2015 and corresponds to the Geology article of Morton et al. (2018; https://doi.org/10.1130/G45354.1). Events were detected using the subspace detection algorithm of Maciera et al. (2010) and located by utilizing direct P and S phase arrival time picks with the hypoinverse location program (Klein et al., 2002). Events that were previously reported in regional earthquake catalogs and the studies of Tréhu et al. (2015; 2018) and Stone et al. (2018) are indicated, as well as the events that were used as templates for subspace scanning. The catalog includes hypocentral locations, origin time, duration magnitudes, number of seismic picks used in location determination, azimuthal gap, event-to-station distance, and location and timing uncertainties. The catalog is separated into three groupings (three ASCII files separated from the one spreadsheet): Earthquakes within a cluster associated with a subducted seamount (150 events), earthquakes within a cluster to the north of the seamount (73 events), and earthquakes not within the clusters (87 events). The data set was generated as part of the project called Developing Methods for Detection and Analysis of Repeating Earthquakes and Low Frequency Earthquakes Using Cascadia Initiative Amphibious Network Data. Funding was provided by NSF grant OCE14-34550, awarded to S.L. Bilek. DOI: 10.1594/IEDA/324617

Description: These six processed multibeam bathymetry grids document the submarine morphology of Aransas Pass and Lydia Ann Channel (Texas) in 2009, 2012, and soon after the passage of Hurricane Harvey in 2017. Aransas Pass is the entrance to the Corpus Christi Ship Channel; it connects the Gulf of Mexico to Corpus Christi Bay to the south and, via Lydia Ann Channel, Aransas Bay to the north. The area was heavily impacted by wind damage and surge waters during Hurricane Harvey. The data files are in NetCDF format (suitable for importing to GMT scripts). The 2009 and 2012 data were collected as part of the University of Texas Marine Geology and Geophysics Field Course, which is funded by multiple donations from companies and individuals (see https://ig.utexas.edu/marine-and-tectonics/ut-marine-geology-geophysics-field-course/). The post-hurricane data were funded by the UT Jackson School of Geosciences Rapid Response Endowment. The three surveys were conducted with a Reson Seabat 8101 (2009), 7101 (2012) and T50-P (2017), with boom-mounted transducers affixed to coastal research vessels. Data were processed using Caris software. Depths are in meters. Mercator projection with WGS84. Navigation and boat attitude were determined with differential GPS and an Applannix IMU. Tide corrections from a local station were applied. However, in comparing different years we found roughly constant offsets in the depths to fixed and immutable objects on the seafloor (including two ship wrecks in Lydia Ann Channel, and jetty bollards in Aransas Pass); the cause of these offsets is not certain. This induced us to apply a constant correction to the 2009 and 2012 data sets (see headers) to align with the 2017 data. DOI: 10.1594/IEDA/324572

Description: This is a sub-set of the data from the Coordinated Canyon Experiment (CCE) that specifically pertains to the published paper, Paull et al., 2018 Powerful turbidity currents driven by dense basal layers Nat Comms 9. doi: 10.1038/s41467-018-06254-6. The full data set is available at http://get.iedadata.org/doi/324762. The CCE was set up to measure the passage of sediment gravity flows down Monterey Canyon. Raw velocity data and raw backscatter data associated with three flow events are provided. The events took place on January 15th 2016, September 1st 2016 and November 24th 2016. The data from the first two events was collected from six moorings MS-1 (300 m water depth), MS-2 (500 m water depth), MS-3 (800 m water depth), MS-4 (1285 m water depth), MS-5 (1449 m water depth), and MS-7 (1850 m water depth), and from a Seafloor Instrument Node (SIN) at 1840 m water depth. Data for the November 24th 2016 event from the MS-1 moorings is also provided. The moorings held downward-looking ADCPs positioned 65 to 70 m above the seafloor. In the SIN, the ADCP’s were at the seafloor looking upwards. All instruments were synced initially on the same time base. MS-1 broke loose during the January 15th 2016 event and the ADCP kept recording while the mooring traveled down canyon and ultimately surfaced. The ADCP at MS-4 did not collect data during the September 1st 2016 event. File names start with the mooring name followed by the type and frequency of ADCP, and the date of the event. Files contain velocity and backscatter data over time. Times are UTC, except for the SIN data from the January 15th 2016 event, which is in local time (UTC is 7 hours ahead). Velocities are reported in millimeters per second and backscatter is reported in the output units of the ADCP, Echo Intensity Units (EIC), which are proportional to decibels. Files were converted to ASCII text format from the RDI proprietary format. Funding was provided by The David and Lucile Packard Foundation, Natural Environment Research Council (NE/K011480/1), U.S. Geological Survey, and Ocean University of China. DOI: 10.1594/IEDA/324529

Description: This magnetic anomaly data was derived from magnetic total field data acquired with a Geometrics G-882 Cesium magnetometer towed 200 m behind the ship. The International Geomagnetic Reference Field was removed from the total field values to produce the magnetic anomaly which was gridded in 0.5 minute cells using GMT-5 software (Wessel et al., 2013). The magnetic survey was conducted at the southern end of the Reykjanes Ridge, a segment of the Mid-Atlantic Ridge, in 2013 during Langseth cruise MGL1309 (investigators Fernando Martinez and Richard Hey). The data file is in PDF format. It is cited in Martinez and Hey, 2017, and was generated as part of the project called Test Between Thermal and Tectonic Hypotheses for North Atlantic Seafloor Spreading Geometry Reorganization.

Description: This three-dimensonal seafloor magnetization data was derived from the magnetic anomaly data. To carry out the inversion for seafloor magnetization the MGL1309 magnetic anomaly grid was extended within a rectangular area using regional gridded values from Macnab et al. (1995) and ship data from Searle et al. (1998) regridded in ~1 km cells. The multibeam bathymetry grid was extended within the same rectangular area using satellite-predicted bathymetry (Sandwell et al., 2014) to fill areas outside the multibeam coverage and regridded in ~1 km cells. The grids were mirrored to minimize edge effects and a three-dimensional Fourier inversion for seafloor magnetization (Parker, 1972) was carried out using Mirone Software (Luis, 2007) assuming a 500 m source layer with magnetization direction given by the axial geocentric dipole. Five terms in the Fourier series were used in the inversion. The resulting values were masked to the extent of the MGL1309 multibeam grid. As the polarity transitions agreed well with two-dimensional reversal modeling of profile values no annihilator was added. The data file is in PDF format. It is cited in Martinez and Hey, 2017, and was generated as part of the project called Test Between Thermal and Tectonic Hypotheses for North Atlantic Seafloor Spreading Geometry Reorganization. Funding was provided by NSF award OCE11-54071.

(1995) and ship data from Searle et al. (1998) regridded in ~1 km cells. The multibeam bathymetry grid was extended within the same rectangular area using satellite-predicted bathymetry (Sandwell et al., 2014) to fill areas outside the multibeam coverage and regridded in ~1 km cells. The grids were mirrored to minimize edge effects and a three-dimensional Fourier inversion for seafloor magnetization (Parker, 1972) was carried out using Mirone Software (Luis, 2007) assuming a 500 m source layer with magnetization direction given by the axial geocentric dipole. Five terms in the Fourier series were used in the inversion. The resulting values were masked to the extent of the MGL1309 multibeam grid. As the polarity transitions agreed well with two-dimensional reversal modeling of profile values no annihilator was added. The data file is in netCDF:GMT grid format. It is cited in Martinez and Hey, 2017, and was generated as part of the project called Test Between Thermal and Tectonic Hypotheses for North Atlantic Seafloor Spreading Geometry Reorganization. Funding was provided by NSF award OCE11-54071. DOI: 10.1594/IEDA/324494

Description: This magnetic anomaly grid was derived from magnetic total field data acquired with a Geometrics G-882 Cesium magnetometer towed 200 m behind the ship. The International Geomagnetic Reference Field was removed from the total field values to produce the magnetic anomaly which was gridded in 0.5 minute cells using GMT-5 software (Wessel et al., 2013). The magnetic survey was conducted at the southern end of the Reykjanes Ridge, a segment of the Mid-Atlantic Ridge, in 2013 during Langseth cruise MGL1309 (investigators Fernando Martinez and Richard Hey). The data file is in netCDF:GMT grid format. It is cited in Martinez and Hey, 2017, and was generated as part of the project called Test Between Thermal and Tectonic Hypotheses for North Atlantic Seafloor Spreading Geometry Reorganization. Funding was provided by NSF award OCE11-54071. DOI: 10.1594/IEDA/324492

Description: The free-air gravity anomaly grid was derived from raw gravity data acquired with a Bell BGM-3 gravimeter and converted to mGal values using the meter constant. A 10 minute cosine taper was then applied to the 1 second values and output at 10 second intervals. Eötvös corrections for ship speed, course and latitude were also applied. The values were adjusted to the gravity tie value at Reykjavik, Iceland, and the International Gravity Formula correction using WGS84 ellipsoid parameters was removed to yield the free-air anomaly. The gravity survey was conducted at the southern end of the Reykjanes Ridge, a segment of the Mid-Atlantic Ridge, in 2013 during Langseth cruise MGL1309 (investigators Fernando Martinez and Richard Hey). The data file is in netCDF:GMT grid format.

Description: This raw temperature data set was acquired with high-temperature HOBO and MISO probes (range 151-419°C) placed in hydrothermal vents at Axial Seamount on the Juan de Fuca Ridge. The probes were deployed for periods of one to several years beginning in 1998. After each deployment each probe was recovered and serviced, the data was downloaded, and the probe was redeployed often at a different vent site. The file names start with the probe ID, followed by the deployment cruise name/year, and end with the vent name. The MISO probes have 2 chips for redundancy and that is reflected in their file names. The files are in text (ASCII) format and were generated as part of a long-term monitoring project at Axial Seamount. Funding was from NSF grants OCE15-46616, OCE13-56839 and OCE11-55849, OCE07-25605 and NOAA/PMEL grants NOAA-8284-2017, NA16OAR4320152, and NA11OAR4320091. DOI: 10.1594/IEDA/324412

Description: This data set was acquired with Scripps Institution of Oceanography LC4X4 Ocean Bottom Seismometers deployed during R/V Marcus G. Langseth expedition MGL1305 in 2013 (Chief Scientist: Juan Pablo Canales, Investigators: Robert Sohn, Juan Pablo Canales, Robert Dunn). OBS recovery took place during R/V Pelagia cruise 64PE382 (Chief scientist: Robert Sohn, Investigators: Juan Pablo Canales, Robert Dunn). The earthquake hypocenter catalog is in ASCII text format. The first column is the event origin time. Note that depth is relative to sea level (i.e., -3.0 equals 3 km below sea level). The RMS value is the misfit of the hypocenter location. Only those events with RMS < 0.2 s were published in the Horning et al., 2018 journal article, but all events with at least 6 body wave arrivals across the network and RMS < 0.5 s are listed in this catalog. The data file was generated as part of the project called MARINER: Seismic Investigation of the Rainbow Hydrothermal Field and its Tectono/magmatic Setting, Mid-Atlantic Ridge 36 Degrees 14'N. Funding was provided by NSF award OCE09-61680. DOI: 10.1594/IEDA/324328

Description: This data set contains processed 2-D electrical resistivity tomography data acquired in July 2015 in the Karonga area of northern Malawi Rift. It was collected using a dipole–dipole array with an Iris Syscal Pro 10-channel resistivity meter. There were 72 electrodes with 10 m electrode spacing. The goal of the survey was to image the structure of the near-surface deformation along the trend of coseismic surface rupture of the St. Mary Fault associated with the 2009 Mw 6.0 Karonga, Malawi earthquake. The data consists of a NNW-SSE profile along the trend of the surface ruptures (Profile 1), and two roughly E-W profiles oriented perpendicular to and across the trend of the surface ruptures (Profiles 2 and 3). Profile 1 is 1070 m long, and Profiles 2 and 3 are 710 m long. The ERT data contains topography information. The data files are in the RES2DINV software ASCII format. More information on the format can be found in the RES2DINV manual at http://www.geotomosoft.com/downloads.php. They were generated as part of the projects called Integrated studies of early stages of continental extension: From incipient (Okavango) to young (Malawi) rifts, and IRES: Research Opportunities in Continental Rift Initiation for U.S. Undergraduate Geoscience Students in Malawi. Funding was provided by NSF awards EAR 1009988 and OISE 1358150. The 2015 Malawi data acquisition team included five 2015 International Research Experience for Students (IRES) participants: B. Clappe, C. Hull, T. Johnson, V. Nyalugwe, and S. Dawson. DOI: 10.1594/IEDA/324326

Description: The Total Magnetic Intensity (TMI) data for the Karonga area of Northern Malawi (IGRF not subtracted) between 9.69S-10.09S and 33.79E-34.09E. This processed airborne magnetic data set is a subset of the Southern African Development Community (SADC) airborne magnetic data set which covers the entire area of southern Africa. The data was acquired in 1984-1985, with a flight elevation of 120 m along NE–SW lines with spacing of 1 km. The tie lines were oriented NW–SE and spaced 10 km apart. The data was gridded at 95 m cell size using a minimum curvature algorithm. The data set is cited in Kolawole et al. (2017) in which it was used as part of the project called "Active deformation of Malawi Rift North Basin hinge zone modulated by reactivation of pre-existing Precambrian shear zone fabric". Funding was provided by NSF award EAR 1009988. The data file is in netCDF grid format. This data set is shared with other researchers for the purpose of research in Malawi only. The Council for Geosciences, South Africa has to be acknowledged as the source of the data. Detailed information on the acquisition parameters for this data (e.g. magnetometer sensor used, acquisition dates, geophysical contractor etc.) can be obtained from the The Council for Geosciences, South Africa.

Description: This data set contains a station information table and a set of stacked receiver function data files. For each OBS station in the StationInfo file, a file exists containing the stacked receiver function for that station under the name Network_StationName_RFStack. The receiver functions are calculated in the vertical-radial-transverse coordinate system and filtered with a 0.1 Hz high pass prior to deconvolution. The time-domain iterative deconvolution method of Ligorria and Ammon (1999) is used to calculation the radial component receiver function from earthquakes that had visible P-wave arrivals. Signals are filtered with a low-pass Gaussian filter during the deconvolution; the data presented here have been filtered with a corner at 0.4 Hz. Each station stack is calculated as a linear stack without move-out correction, normalized by the number of earthquakes that were included. The receiver function data files are in ASCII format and contain two columns. The first column is the time axis in seconds where the zero time is aligned with the P-wave arrival. The second column is the stacked receiver function. The README file included with this archive provides a complete description of the processing that produced the time series. The ASCII station information table contains orientation estimates for the OBS stations. The receiver functions were used to re-calculate the OBS horizontal orientations by performing a grid search for maximum radial component receiver function energy from 0-360 degrees. These values and their uncertainty ranges are given for each OBS in the final three columns of the StationInfo file. The OBS data was acquired during the Cascadia Initiative program. The data files presented here were generated as part of a project called Thermal structure, hydration and dehydration of the entire Juan de Fuca Plate. Funding for this project came from NSF grant OCE13-34831. The data set is referenced in Janiszewski and Abers, 2015. DOI: 10.1594/IEDA/324272

Description: This heat flow data set was derived from Bottom Simulating Reflectors (BSR) imaged using active-source multi-channel seismic data acquired during the Cascadia Open Access Seismic Transects (COAST) survey conducted in 2012 along the Southern Cascadia Margin during R/V Langseth expedition MGL1212. The heat flow data and processing steps are described in Salmi et al., 2017. From each multi-channel seismic profile, the seafloor and BSR travel times were picked, and assuming 50% lithostatic/hydrostatic pressure and normal saline water, the temperatures were estimated. Thermal conductivity was assumed to follow the relationship provided by Davis et al., 1990 which correlates well with borehole data off Vancouver Island. The data file is in ASCII format and contains individual profile line number, common depth point (CDP), latitude, longitude, heat flow and its uncertainty, and seafloor depth derived from multibeam bathymetry also collected during cruise MGL1212. Funding was provided by NSF grants OCE11-44164 and OCE12-49552. Raw geophysical and seismic data can be downloaded from the Lamont-Doherty Earth Observatory Web site (http://www.marine-geo.org/tools/search/entry.php?id=MGL1212). Seismic profiles processed shipboard through post-stack time migration can be downloaded from the University of Texas Institute for Geophysics seismic database (http://www-udc.ig.utexas.edu/sdc/cruise.php?cruiseIn=mgl1212).

Description: Raw seismic reflection sub-bottom data collected with a towed Edgetech 512i CHIRP sub-bottom profiler from Scripps Institution of Oceanography. The data files are in SEG-Y format and contain real-time GPS navigation in the header. The CHIRP towfish included a pressure sensor, allowing the depth of the towfish to be taken into account. As a result, the two-way travel time in the raw CHIRP data is referenced from the sea surface not the towfish. The data set was collected in 2013 in the Beaufort Sea during Healy cruise HLY1302 (investigators Lloyd Keigwin and Neal Driscoll) as part of the project titled "Collaborative Research: Testing the Northern Route for Younger Dryas Meltwater". Funding was provided by NSF awards OPP12-04045, OPP12-03944 and PLR12-04112. DOI: 10.1594/IEDA/324150

Description: This data set is a tomographic model of P-wave seismic velocity structure at the East Pacific Rise between the Clipperton and Siqueiros fracture zones. The model was derived from active-source data acquired during the UNDERSHOOT seismic tomography experiment conducted during Ewing cruise EW9708 in 1997 (chief scientist Doug Toomey). The model and results are described in Toomey et al. (2007). Analysis and interpolation of two-dimensional crustal velocity profiles provided a 3-D starting model for the tomographic inversions in which off-axis crustal structure and thickness were constrained using crustal refractions and Moho reflections. Using a non-linear method for imaging heterogeneous and anisotropic structures, almost 5,000 Pn mantle refraction arrival times were analysed in the tomographic inversion. The data file is in ASCII format and contains longitude, latitude and velocity. It is masked by the derivative weight sum with values provided where there is data sampling and the results are for a region that is conformal to the seafloor and at approximately 9 km beneath the seafloor. The data set was generated as part of the project called Constraining Mantle Flow, Melt Supply, and Lower Crustal Structure Between the Clipperton and Siqueiros Fracture Zones from a Seismic Undershoot Experiment. Funding was provided by NSF awards OCE01-18597, OCE96-33264, OCE01-18383, OCE96-33814, OCE01-18450, OCE02-24903, OCE96-34132 and OCE01-17715. DOI: 10.1594/IEDA/324051

Description: This data set is a tomographic model image of P-wave seismic velocity structure at a shallow mantle depth of 7.8km beneath the seafloor at the Juan de Fuca Endeavour Ridge. The model was derived from active-source data acquired during the ETOMO 3-D seismic tomography experiment conducted during Langseth cruise MGL0910 in 2009 (chief scientists Doug Toomey, Emilie Hooft, William Wilcock). The model and results are described in VanderBeek et al. (2016). Using a 3-D starting model of crustal velocity and thickness from previous tomographic studies of crustal refractions and Moho reflections, an iterative tomographic inversion was performed with more than 5,000 hand-picked Pn mantle refraction arrival times. Travel-time residuals were inverted for 3-D slowness perturbations, and ray paths and travel-times were predicted using a shortest-path algorithm. Ray tracing was performed on a 3-D grid parameterized with anisotropic slowness and seafloor topography. Azimuthal variations in Pn travel-time residuals were used to identify segment-scale anisotropic structure. The data set is in PDF format. It was generated as part of the projects called ETOMO: Endeavour Seismic Tomography Experiment and Testing Models of Magmatic and Hydrothermal Segmentation: A 3-D Seismic Tomography Experiment at the Endeavour Ridge. Funding was provided by NSF Ridge 2000 program grants OCE04-54747 and OCE04-54700. DOI: 10.1594/IEDA/324050

Description: This data set presents images showing residual free-air gravity anomalies for global subduction zones. Residuals are calculated by subtracting a regional spectral average of the trench-normal gravimetric expression across the subduction zone. This procedure removes the steep gradients associated with the seaward and landward trench-slopes, significantly improving the identification of short-wavelength lower-amplitude structure. The image files are in PDF format and were generated from gridded data files. The residual gravity is cited in Bassett and Watts, 2015a,b.

Description: This dataset contains high-resolution ASCII:ESRI gridded bathymetric data (0.5 m DTM). Data was collected during a six-months survey (lasting from May to December 2013) in the channel network of the Venice Lagoon by means of the MBES system Kongsberg EM-2040 Compact dual head. The MBES was mounted on a pole at the bow of the CNR research vessel Litus, a 10-m long boat with only 1.5-m draft. The MBES has 800 beams (400 per swath) 1°x1°; the operational frequency for this survey was set at 360 kHz. A Seapath 300 system was used for ship positioning, improving its accuracy by the correction provided by a Fugro HP differential Global Positioning System (DGPS, accurate up to 0.2 m). Tidal correction of bathymetric data was based on a set of virtual tidal stations (93 points) distributed evenly around all the study area. The tidal corrections in each virtual tide gauge station were calculated using the water level simulated by the hydrodynamic model SHYFEM (Umgiesser et al., 2014) applied to the whole Venice Lagoon. Data was processed after collected using CARIS to account for sound velocity profiles, tide corrections, and manual quality control tools. The base surfaces were created with the Swath Angles Weighting option with a Max Footprint size of 9x9 pixels and a resolution of 0.5 m and cleaned using the subset editor to efficiently handle and visualize. The raw data are stored in the CNR-ISMAR Venice server and available under request to data owner. Data collection have been founded thanks to the Italian Italian Flagship Project RITMARE. The datafile iim_malamocco.asc was collected by the Italian hydrographic Institute (IIM Istituto Idrografico della Marina) by means of the MBES system Kongsberg EM3002 on board of the vessels MBN1148 and MBF1213. The Italian Hydrographic Institute processed the bathymetric using CARIS HIPS AND SIPS 7.1. Data are licensed under CCBY 4.0. DOI: 10.1594/IEDA/323605
