Physical Properties Derived from Gravity Cores acquired during Long Island Sound Mapping Project Phase II
Author(s): Nitsche, Frank; Kenna, Timothy; McHugh, Cecilia
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.

Sediment Core Images from samples acquired as part of the Long Island Sound Mapping Project Phase II
Author(s): Nitsche, Frank; Kenna, Timothy; McHugh, Cecilia
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. 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).

Sediment Geochemistry Data derived from Gravity Cores acquired as part of Long Island Sound mapping project Phase II
Author(s): Kenna, Timothy; Nitsche, Frank; McHugh, Cecilia
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.

Sentry processed near-bottom high-frequency sidescan images (GeoTIFF format) from the East Pacific Rise, RR2106 (2021)
Author(s): White, Scott; German, Christopher; Resing, Joseph
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). The high-frequency sidescan data was collected at 540 kHz and at ~15 m altitude or lower, except during multibeam surveys on dives 599, 603 and 604, as described in the accompanying sidescan data processing document. 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?

Sentry processed near-bottom low-frequency sidescan images (GeoTIFF format) from the East Pacific Rise, RR2106 (2021)
Author(s): White, Scott; German, Christopher; Resing, Joseph
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.

First arrival tomography-derived velocity models for Oneida Lake, New York
Author(s): Zaremba, Nicholas; Scholz, Christopher
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

Images for processed seismic profiles 02, 11, and 15 (JPEG format) across the Santorini-Amorgos Tectonic Zone from Poseidon cruise POS338 (2006)
Author(s): Hubscher, Christian; Preine, Jonas
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 profile images presented here are in JPEG 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/331029

Pressure and temperature time-series data from the CORK in Hole 395A in North Pond acquired from 1997-2007
Author(s): Becker, Keir; Davis, Earl
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

Heat flow data from the Pescadero Basin, Gulf of California (2021, ROV SuBastian, FK210922)
Author(s): Negrete-Aranda, Raquel; Neumann, Florian; Harris, Robert
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

Seismic velocity model images, Eastern North American Margin Community Seismic Experiment (ENAM CSE)
Author(s): Shuck, Brandon; vanAvendonk, Harm; Becel, Anne
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

Seismic velocity model geometries, Eastern North American Margin Community Seismic Experiment (ENAM CSE)
Author(s): Shuck, Brandon; vanAvendonk, Harm; Becel, Anne
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.

Seismic velocity model layers, Eastern North American Margin Community Seismic Experiment (ENAM CSE)
Author(s): Shuck, Brandon; vanAvendonk, Harm; Becel, Anne
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. 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.

Seismic velocity grids, Eastern North American Margin Community Seismic Experiment (ENAM CSE)
Author(s): Shuck, Brandon; vanAvendonk, Harm; Becel, Anne
Description: These 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. 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. 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.

Processed CHIRP SEG-Y sub-bottom profile images from the Sacramento-San Joaquin Delta, CA, October 2017
Author(s): Klotsko, Shannon; Maloney, Jillian; Watt, Janet
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.

Gridded bathymetry for Lake Malawi (Nyasa), East Africa (within Malawi, Tanzania, Mozambique)
Author(s): Scholz, Christopher; Lyons, Robert
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

Raw 2-D multichannel seismic reflection SEG-D shot data from Oneida Lake, New York (2019)
Author(s): Scholz, Christopher; Zaremba, Nicholas
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

Processed bathymetry images (GeoTIFF image format) derived from Geoswath multibeam data in Eastern Long Island Sound (2017-2018)
Author(s): Babb, Ivar; Arbige, Dennis
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). 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).

NZ3D seismic reflection data volume – Preliminary post-stack time migration (PSTM)
Author(s): Bangs, Nathan; Han, Shuoshuo
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

Processed Unmigrated Time Stack, Prestack Depth-Migrated, and Depth-to-Time-converted seismic data from the EDGE-302 deep crustal seismic reflection transect of the eastern Aleutian arc-trench
Author(s): Miller, John; Klaeschen, Dirk
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.

Author(s): Sutherland, Rupert; Shuck, Brandon
Description: This data set presents processed Multi-Channel Seismic (MCS) reflection data in segy format. The 1996 EW9601 seismic survey gathered MCS data with the R/V Maurice Ewing along a transect spanning the southern shelf of the South Island of New Zealand. A single profile, P1, crossing the Puysegur subduction zone, was recovered and re-processed from the original field data. EW9601_p1_shots.sgy contains a minimal amount of processing and represents the recovered shots from the original raw field data converted to SEG-Y format with corrected headers. EW9601_edited_shots.sgy contains cleaned shot gathers in SEG-Y format with filtering, noise removal, and bad channels killed (see related image file for before/after). EW9601_radon_cdps.segy contains sorted CDP gathers in SEG-Y format with radon multiple suppression applied (see related image file for before/after). EW9601_PSTM.sgy represents a final pre-stack time-migrated reflection gather in SEG-Y format which was migrated using the related EW9601_intervels_updated.txt interval velocity model (see related image for comparison of this PSTM gather to original time-migrated gather). Details of the processing workflow are described in the linked data processing README document. DOI: 10.26022/IEDA/330863

Processed OBS seismic refraction data from the 2018 SISIE seismic survey (MGL1803)
Author(s): vanAvendonk, Harm; Gulick, Sean; Gurnis, Michael; Shuck, Brandon
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

Processed 2-D multichannel seismic reflection data from Oneida Lake, New York (2019)
Author(s): Scholz, Christopher; Zaremba, Nicholas
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

Navigation data for processed 2-D multichannel seismic reflection data from Oneida Lake, New York (2019)
Author(s): Scholz, Christopher; Zaremba, Nicholas
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. Funding was provided through NSF grant EAR18-04460 to Syracuse University. DOI: 10.26022/IEDA/330834

Navigation (KML format) for CHIRP SEG-Y sub-bottom data from the All-American Canal near Calexico, CA, April 2019
Author(s): Sahakian, Valerie; Derosier, Boe; Rockwell, Thomas; Stock, Joann
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

Microseismicity earthquake catalog, Endeavour Segment, Juan de Fuca ridge, 1995-2021
Author(s): Krauss, Zoe; Wilcock, William
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. The data files are 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 the paper "A long-term earthquake catalog for the Endeavour segment of the Juan de Fuca Ridge: Influence of propagating rifts on segment dynamics and hydrothermal venting" (Krauss et al., 2022). 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

T-phase location catalog for equatorial Atlantic ocean, 2011-2015
Author(s): Parnell-Turner, Ross; Dziak, Robert; Smith, Deborah
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

Preliminary 1-meter resolution bathymetric model (ASCII grid format) for the distal South Rift Zone region of Axial Seamount, version as of 31 October 2019
Author(s): Clague, David; Caress, David; Paduan, Jennifer; LeSaout, Morgane
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. The grid is in ESRI ASCII format in the geographic WGS-1984 coordinate system and has 1-m horizontal resolution, with square cells for use with GIS. Funding for the work was provided through annual grants to MBARI from the David and Lucile Packard Foundation. DOI: 10.26022/IEDA/330466

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.

Audio-quality hydrophone data from Yellowstone Lake - Deep Hole thermal area, August, 2017
Author(s): Sohn, Robert
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

Processed bathymetry data (GeoTIFF grid format) for Paterson Inlet, Stewart Island, New Zealand
Author(s): Dagg, Bob
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.

Earthquake microseismicity catalog of the Quebrada transform fault system at ~3.7°S, East Pacific Rise, 2008
Author(s): Gong, Jianhua; Fan, Wenyuan; Parnell-Turner, Ross
Description: This microseismicty 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. Funding was provided by NSF awards OCE 0242117 and OCE 1833279. DOI: 10.26022/IEDA/330427

Raw high-temperature time series data from the East Pacific Rise 9°50'N hydrothermal vents M and Q (2004-2006)
Author(s): Barreyre, Thibaut; VonDamm, Karen; Fornari, Daniel; Parnell-Turner, Ross; McDermott, Jill
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.

Raw USBL navigation data acquired for the deep-towed electric field survey over the southern Hikurangi margin during Tangaroa cruise TAN2012 (2020)
Author(s): Kannberg, Peter; Constable, Steven; Hillman, Jess
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

Raw deep-towed electric field data acquired over the southern Hikurangi margin during Tangaroa cruise TAN2012 (2020)
Author(s): Kannberg, Peter; Constable, Steven; Hillman, Jess
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.

India-Somalia Chrons 1-26 plate reconstruction data: northern Indian Ocean
Author(s): DeMets, Charles
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

Preliminary 1-meter resolution bathymetric model command script for data collected over the summit region of Axial Seamount, version as of 10 March 2021
Author(s): Clague, David; Caress, David; Paduan, Jennifer
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.

Preliminary 1-meter resolution bathymetric model (ESRI ASCII grids) for the summit region of Axial Seamount, version as of 10 March 2021
Author(s): Clague, David; Caress, David; Paduan, Jennifer
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. 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.

Seafloor gravity measurements across the TAG Hydrothermal Mound on the Mid-Atlantic Ridge (1994)
Author(s): Evans, Robert; Galley, Christopher
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/backscatter 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. Backscatter intensity surfaces with a horizontal resolution of 1 m (3.28 feet) were generated in the Fledermaus FGMT software. The data file is in GeoTIFF grid format.

Grain-size data of surface sediment samples from the North Carolina shelf post-Hurricane Florence (2019 survey)
Author(s): Walsh, John, P.; Freeman, Chris; Sumners, Ben; Corbett, D.Reide
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. Walsh. DOI: 10.26022/IEDA/330104

Processed bathymetry data (netCDF grid format) of selected seamounts along the Southwest Indian Ridge, James Cook cruise JC066, 2011
Author(s): Rogers, Alex, David; Watts, Anthony; Muller, Lily
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

Galapagos Island bathymetry data (netCDF grid format) from cruise AL150801 (2015)
Author(s): Soule, S.Adam; Wanless, Dorsey; Fornari, Daniel
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.

Processed high-resolution 3-D multi-channel seismic data volume from a hybrid PCable and long-offset survey on the New Jersey margin - MGL1510
Author(s): Mountain, Gregory; Nedimovic, Mladen; Fulthorpe, Craig; Austin, James
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

Raw Geoswath bathymetry and sidescan data (RFF format) in Eastern Long Island Sound (2018)
Author(s): Babb, Ivar; Arbige, Dennis
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).

Machine-learning predicted logarithmic values of marine mass accumulation rates on the seafloor
Author(s): Restreppo, Giancarlo; Wood, Warren; Graw, Jordan; Phrampus, Benjamin
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: Identifications of magnetic reversals from Anomaly 1 (0.78 Ma) to Anomaly 6 (~20 Ma) from a wide range of shipboard and airborne magnetic data from the Arctic Basin and northern Atlantic spreading centers 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 Eurasia-North America plate rotation sequence described by Merkouriev and DeMets (2014). 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. DOI: 10.26022/IEDA/329892

Bathymetry data (GeoTIFF grid format) of the Northern-most Adriatic area: Interreg Ita-Slo 2007-2013 TRECORALA Project
Author(s): Gordini, Emiliano; Ciriaco, Saul
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

Deep Tow depth profiles from the East Pacific Rise at 17°S and 19°S (PANR06MV, 1998)
Author(s): Gee, Jeffrey; Parnell-Turner, Ross
Description: These depth profiles were acquired simultaneously with the deep-tow sidescan data (pressure+down: P+DN). The data files are in ASCII format and contain lon, lat, depth (depth is positive downwards). 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 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. Funding was provided through NSF awards OCE97-12027, OCE14-59387 and OCE18-39727. DOI: 10.26022/IEDA/329857

Near-bottom processed sidescan sonar Deep Tow mosaiced grids from the East Pacific Rise at 17°S and 19°S (1998)
Author(s): Gee, Jeffrey; Parnell-Turner, Ross
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. Funding was provided through NSF awards OCE97-12027, OCE14-59387 and OCE18-39727. DOI: 10.26022/IEDA/329856

Calibration sheets used with seafloor APG pressure data from trench-perpendicular benchmarks on the Cascadia margin, offshore central Oregon
Author(s): Wilcock, William; MacCready, Parker; Schmidt, David; Roland, Emily; Fredrickson, Erik
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

Continuous seafloor APG pressure and temperature data from trench-perpendicular benchmarks on the Cascadia margin, offshore central Oregon
Author(s): Wilcock, William; MacCready, Parker; Schmidt, David; Roland, Emily; Fredrickson, Erik

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 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. This data set was generated as part of the project called Constraints on Interseismic Deformation Offshore Oregon from Calibrated Continuous Pressure Records.

ROV Jason II seafloor bottom photos at the Havre Volcano Caldera in the Kermadec Arc (RR1506, 2015)
Author(s): Soule, S.Adam; Carey, Rebecca
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

Heat flow and thermal gradient data for the HD-YLAKE project, Yellowstone Lake, 2016-2018
Author(s): Harris, Robert; Favorito, Julia; Sohn, Robert
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.

Single-beam bathymetry data (GeoTIFF image format) of selected mesophotic biogenic reefs from the northern Adriatic Sea
Author(s): Ponti, Massimo
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

Bathymetry data (GeoTIFF image format) of the Northern Adriatic Tegnùe di Chioggia site collected in 2014-2015 for the DeFishGear project
Author(s): Fortibuoni, Tomaso; Canese, Simonepietro; Bortoluzzi, Giovanni; Franceschini, Gianluca; Giovanardi, Otello
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

LIS phase 2 LDEO sediment grab bottom videos (2017, 2018)
Author(s): Nitsche, Frank; Kenna, Timothy; McHugh, Cecilia
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).

LIS phase 2 LDEO sediment grab bottom photos (2017, 2018)
Author(s): Nitsche, Frank; Kenna, Timothy; McHugh, Cecilia
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.

Processed time-stacked data (SEG-Y format) for 2-75 Ma equatorial Atlantic ocean floor acquired in 2015 as part of the TransAtlanticILAB project
Author(s): Audhkhasi, Pranav; Singh, Satish
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

Author(s): Parianos, John
Description: This data set consists of processed total magnetic field data collected with an Applied Physics Systems 534D Fluxgate magnetometer attached to a deep-tow sled system towed behind the cruise vessel. A total of 69 survey lines were collected, oriented along N36E, and covered a roughly 44x24 km area encompassing the Tumai and Bugave Ridges, as well as the Kaia Natai volcano. The data file is written in the TetGen ASCII NODE format (https://wias-berlin.de/software/tetgen/fformats.node.html) with the following columns: point_index, UTM x (m), UTM y (m), elevation (m), total magnetic field (nT). The UTM zone is 56M, with a reference meridian of 153 degrees E. The IGRF is not removed from the total magnetic field data column. All data were collected by Nautilus Minerals from December 2016 to March 2017, in collaboration with the Mineral Resources Authority of Papua New Guinea. The cruise was funded by Nautilus Minerals.

Single-beam bathymetry data (ESRI ASCII grid format) of selected mesophotic biogenic reefs from the northern Adriatic Sea
Author(s): Ponti, Massimo
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. The lead investigator for this project was Massimo Ponti. DOI: 10.26022/IEDA/329803

Gas hydrate assessment of public industry well logs from the Barents and Norwegian Seas
Author(s): Cook, Ann; Heber, Ryan; Portnov, Alexey
Description: This data set contains a gas hydrate assessment from 64 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 data 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. Funding was provided from NSF CAREER award OCE17-52882. DOI: 10.26022/IEDA/329783

Pre-stack Depth Migrated (PSDM) seismic reflection data across the NE Hawaiian Arch (NE of Oahu) from JAMSTEC cruise KR17-4 (2017)
Author(s): Yamashita, Mikiya; Nakrong, Nipaporn
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.

Catalog of impulsive acoustic events identified for the April-May 2015 eruption of Axial Seamount
Author(s): Bohnenstiehl, DelWayne; Mann, M.Everett
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

GeoTIFF images of gridded near-bottom bathymetry from the north rift zone of Axial Seamount (2016 RCSN392 survey)
Author(s): Clague, David; Caress, David; Paduan, Jennifer; LeSaout, Morgane
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

Raw temperature data acquired during the HyLO probe test at Fincastle Lake, Texas, 2019
Author(s): Hornbach, Matthew; Sylvester, Joshua; Hayward, Chris
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 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.

Author(s): Bouligand, Claire; Tivey, Maurice; Finn, Carol; Morgan, Lisa; Shanks, Pat; Sohn, Robert
Description: This data set consists of interpolated grids over the Deep Hole hydrothermal site in northern Yellowstone Lake collected in July 2016 by Ocean Floor Geophysics Inc. (OFG) (https://www.oceanfloorgeophysics.com/). The two interpolated grids provide the following: (a) the depth (data depth) below the lake surface (mean lake surface elevation value is 2358m above sea-level) and (b) altitude (data height) above the lake floor of the surface on which the 7m-above-lake-floor magnetic anomaly grid was interpolated. The magnetic field anomalies at approximately 7m above the lake floor are interpolated onto a horizontal grid spacing of 10m. The files are in GMT-compatible netCDF grid format. Details of the grid interpolation and analysis are explained in Bouligand et al., 2020. 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 and WHOI internal funds. During the course of this study, Claire 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. 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. DOI: 10.26022/IEDA/329678

Lake surface magnetic anomaly data (netCDF format) for the HD-YLAKE project, Yellowstone Lake
Author(s): Bouligand, Claire; Tivey, Maurice; Finn, Carol; Morgan, Lisa; Shanks, Pat; Sohn, Robert
Description: This data set consists of a merged grid of magnetic field anomaly over northern Yellowstone Lake and adjacent area from three surveys draped over topography and the lake surface with a grid spacing of 25 m. To compute this grid the measured data values were reduced to the level of the lake surface (2358 m) and topography surrounding the lake. The file is in GMT-compatible netCDF grid format. The combined data sets consist of a 2016 lake level magnetic survey, a 2016 a low-altitude aeromagnetic survey collected by USGS [Finn et al., 2020] and a regional higher altitude aeromagnetic survey collected by USGS in 1997 [U.S. Geological Survey, 2000; Finn and Morgan, 2002]. Details of the grid merging and analysis procedures are explained in Bouligand et al., 2020.The lake surface and AUV magnetic data sets were acquired under National Park Service research permit YELL-2016-SCI-7018 and the 2016 aeromagnetic data was collected under research permit YELL-2016-SCI-7056.Maurice Tivey was supported under NSF IPA grant 1557455 to WHOI and WHOI internal funds.

Multibeam bathymetric and backscatter data, Emperor Seamounts and Hess Rise, R/V Falkor cruise FK190726 (2019, investigators Les Watling and John R. Smith)
Author(s): Watling, Les; Smith, John
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. Funding was provided by an award 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. This data was included in the Global Multi-Resolution Topography (GMRT) Synthesis (version 3.8). DOI: 10.26022/IEDA/329665

Lake surface track line navigation and magnetic anomaly data for the HD-YLAKE project, Yellowstone Lake, 2016
Author(s): Bouligand, Claire; Tivey, Maurice; Finn, Carol; Morgan, Lisa; Shanks, Pat; Sohn, Robert
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.

Gridded bathymetric data around Pico, Faial, and Sao Jorge islands, Azores (2003 survey)
Author(s): Mitchell, Neil; Tempera, Fernando
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
