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

SOTW06WT Deep Tow vehicle navigation, South Tow leg 6 (1972)
Author(s): Mitchell, Neil
Description: This data set consists of Deep Tow vehicle navigation files for Galapagos Spreading Centre 1972 cruise SOTW06WT. These ASCII navigation files were generated by Neil Mitchell at the University of Manchester as follows. According to Klitgord & Mudie (1974), a network of six bottom transponders was originally deployed for the survey. Acoustic ranging between them, the Deep Tow vehicle and the ship enabled their relative positions to be calculated for most of the survey duration, with an internal accuracy of ~40 m. For the remaining one-third of the survey, it is unclear how the vehicle position was calculated although a cable trajectory model is mentioned in Klitgord and Mudie (1974) for a line over the northerly flank, which may have been used more widely. In addition, satellite fixes of the vessel allowed the survey to be placed in a geographic framework with an accuracy of ~0.5 km (after digitising accuracy is included, position accuracy will be somewhat poorer than this). A vehicle track map originally produced by Bob Detrick was digitised to generate (x, y, survey time) and these values were merged with digital data files obtained from the Marine Physical Laboratory at Scripps Institution of Oceanography to produce (x, y, Deep Tow vehicle depth, bathymetry at the Deep Tow position, survey time). The navigation files presented here contain these positional values updated with geographical coordinates that were obtained from longitude = X * 7.963700000000E-06 - 86.179455500; latitude = Y * 8.728372093023E-06 + 0.56179069767, where X and Y are the local coordinates in meters. That is, a flat-Earth approximation is used and is justified given the small geographical area and the age of the data (position uncertainty is larger than projection error). The X and Y values are also in the files. DOI: 10.26022/IEDA/331450

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

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

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

Residual mantle Bouguer anomaly (RMBA) grid, 42-50 Ma NE Pacific between Molokai and Murray FZ
Author(s): Blackman, Donna; Laske, Gabrielle
Description: Residual mantle Bouguer anomaly grid calculated for the Ohana project located 25-30.5°N, 145.5-137.5°W in the NE Pacific. This ~500x600 km area was the site of an Ocean Bottom Seismometer array deployed Nov 2021-Feb 2023 by a team led by Gabi Laske. Donna Blackman led the bathymetric and gravity analyses. Gravity data processing started with the satellite-based Free Air Anomaly grid (grav_32.1.nc, Sandwell et al., 2014). The contributions of seafloor topography (from the corresponding bathymetry grid called Ohana_bathymetry_200m.grd), and of a constant thickness (6 km) crust were removed assuming 1900 and 400 kg/m3 density contrasts at the interfaces, respectively. The best-fit square-root of age trend of the predicted mantle Bouguer anomaly was removed as a conservative estimate of the contribution of plate cooling with age. The resultant RMBA data was gridded at 200 m. The RMBA data file is in GMT-compatible netCDF grid format. DOI: 10.26022/IEDA/331358

Southwest Indian Ridge (SWIR 9-16E) residual mantle Bouguer gravity anomaly data (netCDF format)
Author(s): Lin, Jian; Dick, Henry
Description: Shipboard free-air gravity data were processed in the same way as described by Wang et al. (2015) to obtain Residual Mantle Bouguer Anomaly (RMBA): The gravitational effects of seafloor topography and relief on the crust-mantle interface were subtracted from the free-air gravity anomaly to obtain mantle Bouguer anomaly (MBA), assuming a reference crustal thickness of 6 km and using the spectrum method of Parker (1973). Densities of water, crust, and mantle were assumed to be 1.03 10^3, 2.7 10^3, and 3.3 10^3 kg m^-3, respectively. RMBA was then calculated by removing the gravitational effect of lithospheric cooling from MBA, based on a 3-D mantle thermal model. The mantle thermal structure was calculated for a 100 km thick layer, using the 2-D age grid of Wang et al. (2015) and assuming simple 1-D plate cooling (Turcotte and Schubert, 2002; Wang et al., 2011). The parameters used in the calculation are the same as in Wang et al. (2011). This mantle thermal model was then converted to a 3-D mantle density structure, which was used to calculate gravitational effects. The data file is in GMT-compatible netCDF grid format.

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

Processed PROBE multi-channel seismic dip and strike profiles acquired in 1986-1987 along the Lake Malawi (Nyasa) Rift
Author(s): Scholz, Christopher; Rosendahl, Bruce
Description: There are 28 Multi-Channel Seismic lines, collected in 1986/87 across the Central and South Basins of the Lake Malawi Rift as part of the PROBE project (Proto-Rifts and Oceanic Basin Evolution) of Duke University. All files are in SEG-Y format, with coordinate reference system and navigation information in the headers. The projection is UTM-36S. The record length is 6 seconds two-way travel time, 4 ms sample rate. Profiles are generally oriented east-west across multiple rift segments. Data were acquired aboard R/V Nyanja, a 36-foot-long dedicated geophysical vessel transportable by cargo aircraft. Source was a single 140 cubic inch EERI airgun, or 3x40 cubic inch array of GSI sleeve guns. Streamer was a GECO custom-built 960 m active-length cable comprising 48 groups (20 m group interval); lead-in cable length varied from 250-440 m. Streamer depth was nominally 10 m and controlled a buoy suspension system. Fold coverage was nominally 24-fold. Acquisition was via Texas Instruments DFS-V, at 2 ms sample rate. Navigation was by transit satellite, radar, automatic speed log and deduced reckoning. Navigational accuracy ranges from <100 m to several km in places. Every line is controlled by a minimum of two fixes and a 40-80 km line is controlled by 5-8 good fixes. Chief Scientist was Bruce R. Rosendahl. Data were recovered from 9-track tape and archived on modern media under the supervision of Christopher A. Scholz, Syracuse University. Legacy time processing at Duke University was completed with Digicon DISCO 50 software on a DEC VAX 11/750 computer, applying the following workflow: Demultiplexing, Resample, Geometry Definition, Trace Edit, Sort, Deconvolution, Filter, Velocity Analysis, Stacking, Mute, Migration, Display. Deconvolution is a predictive gap deconvolution, occasionally spiking deconvolution is used. Filtering was variable, typically a bandpass filter with a Hanning taper was employed with typical cutoffs of 6-10 Hz at the low end, and 50-55 Hz at the upper end. Some lines received time-variant filtering and occasionally notch filters were used. Select lines were subjected to a post-stack finite difference time migration routine. Funding for data collection and processing was from multiple 1980s-era oil and gas companies. DOI: 10.26022/IEDA/331340

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

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

Mid-Atlantic Ridge South of Kane FZ (21.75N-23.8N) residual mantle Bouguer gravity anomaly data (netCDF format)
Author(s): Cann, Joseph; Smith, Deborah; Escartin, Javier
Description: RMBA anomalies were digitized from Maia and Gente (1998) and used by Cann et al. (2015) to interpret the tectonic evolution of 200 km of Mid-Atlantic Ridge over 10 million years and the interplay of volcanism and faulting. The gravity data were collected during two cruises, RC2511 (Detrick et al., 1984) and SEADMA I (Gente et al., 1995) and combined with available data sets from NOAA - National Centers for Environmental Information, and the 1991 SIGMA cruise (from the Banque de Bathymetrie et Geophysique Marine (SISMER) data bank, France). Processing of the data is described in Maia and Gente (1998). The MBA was computed assuming a constant crustal thickness model (Prince and Forsyth, 1988) using the method of Parker (1973). Crustal thickness was assumed to be 6 km. Densities of seawater, crust and mantle were considered constant (1030, 2700, and 3300 kg/m3, respectively). The thermal correction was computed using a passive flow model (Phipps Morgan and Forsyth, 1988) to obtain the RMBA. The data file is in GMT-compatible netCDF grid format. DOI: 10.26022/IEDA/331314

Southwest Indian Ridge mantle Bouguer and residual mantle Bouguer gravity anomaly data (netCDF format) between 61°-67°E
Author(s): Cannat, Mathilde
Description: Off-axis geophysical surveys provide a 26-m.y.-long record of axial tectonic and magmatic processes over a 660-km-long and melt poor portion of the ultraslow Southwest Indian Ridge. The data reveal a new type of seafloor (the smooth seafloor) that forms at minimal ridge melt supply, with little or no axial volcanism. The gravity data were primarily collected during Marion Dufresne cruise 135 in 2003 (https://campagnes.flotteoceanographique.fr/campagnes/3200080/). Details of the processing of the gravity data are provided in the Supplement Material section of Cannat et al. (2006). The residual mantle Bouguer anomaly (RMBA) was calculated from free-air ship gravity data by first subtracting the effect of topography of a constant crustal thickness (3.4 km; the mean seismic crustal thickness determined near 66°E (Muller et al., 1999)), constant density (2700 kg/m3) crust, and then the effect of upper mantle cooling with age (using magnetic anomaly picks). The thermal correction model assumes a simple square root of age mantle cooling law (Parsons and Sclater, 1977). The thermal model was cut off 25 km off-axis, and a constant temperature gradient used in the intervening axial region. The data files are in GMT-compatible netCDF grid format. The "mba" grid is the mantle Bouguer anomaly data and the "rmba" grid is the residual mantle Bouguer anomaly grid. DOI: 10.26022/IEDA/331313

Residual mantle Bouguer gravity anomaly data (netCDF format) in a corridor across the Mid-Atlantic Ridge at 24°-27°N
Author(s): Tucholke, Brian; Lin, Jian
Description: Shipboard free-air gravity data from R/V Ewing Cruises EW9208 and EW9606 in the Mid-Atlantic Ridge corridor at 24°-27°N were processed as described by Wang et al. (2015) to the obtain Residual Mantle Bouguer Anomaly (RMBA): The gravitational effects of seafloor topography and relief on the crust-mantle interface were subtracted from the free-air gravity anomaly to obtain mantle Bouguer anomaly (MBA), assuming a reference crustal thickness of 6 km and using the spectrum method of Parker (1973). Densities of water, crust, and mantle were assumed to be 1.03 10^3, 2.7 10^3, and 3.3 10^3 kg m^-3, respectively. RMBA was then calculated by removing the gravitational effect of lithospheric cooling from MBA, based on a 3-D mantle thermal model. The mantle thermal structure was calculated for a 100 km thick layer, using the 2-D age grid of Wang et al. (2015) and assuming simple 1-D plate cooling (Turcotte and Schubert, 2002; Wang et al., 2011). The parameters used in the calculation are the same as in Wang et al. (2011). This mantle thermal model was then converted to a 3-D mantle density structure, which was used to calculate gravitational effects. Note that, within a narrow axial region that contains ridge-axis offsets, this 1-D plate cooling model differs slightly from the 3-D passive mantle upwelling model used in Tucholke et al. (1997), in which lateral heat transfer across ridge offsets was considered. Thus, the calculated thermal structure and resultant gravity corrections for the 3-D passive upwelling model are smoother across ridge offsets than those predicted by the 1-D plate cooling model. However, differences between the two models are only a few mGal and are limited to a narrow zone proportional to the size of ridge offsets. The file presented here is in GMT-compatible netCDF grid format. Additional gravity and other shipboard data in this region are available at https://doi.org/10.26025/z2z7-kd89. Ewing Cruise EW9208 was funded by Office of Naval Research grant N00014-90-J-6121, and Ewing Cruise EW9606 was funded by National Science Foundation grant OCE-9503561. DOI: 10.26022/IEDA/331312

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

Heat flux data from the MARGIN seep site, 2022 (MGL2208)
Author(s): Spinelli, Glenn; Harris, Robert; Trehu, Anne
Description: The MARGIN site is at a buried basement high (likely a buried seamount) offshore Oregon, ~25 km seaward of the Cascadia subduction zone deformation front. The buried basement high rises ~1300 m above the surrounding basaltic basement. The MARGIN basement high was first identified on the north-south-trending MARGIN transect, collected as part of the Juan de Fuca Ridge-to-Trench project; that seismic transect crossed the flank of the MARGIN basement high. Subsequently, the east-west-trending Line PD11 collected as part of the MGL2104 CASIE21 project conducted in 2021 crossed a higher and more substantial portion of the MARGIN basement high. In 2022, in-situ measurements of thermal gradient were collected crossing and around the MARGIN basement high using a 3.5-m violin-style heat flow probe. This multi-penetration heat flow probe was loaned from the U.S. Marine Heat Flow Capability. The thermistor string houses 11 thermistors. The in-situ thermal gradient is combined with an assumed thermal conductivity versus depth trend to determine the heat flow. The data was processed using SlugHeat (https://marine-heatflow.ceoas.oregonstate.edu/software/). The data file is in ASCII tab-separated format, with column headers. Funding was provided by National Science Foundation awards OCE19-24331, OCE20-34872, and OCE20-34896. DOI: 10.26022/IEDA/331310

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

Gridded bathymetry data from Galapagos Marine IGUANA OBS deployment cruise MGL2304 (2023)
Author(s): Hooft, Emilie; VanderBeek, Brandon
Description: Along-track hull-mounted EM122 multibeam swath bathymetry data was collected within a region 300 x 300 km to the west, south, and north of the Galápagos islands. Also covered was the northern portion of the new Ecuadorian Hermandad Marine Reserve. The swath data was acquired during the 2023 Marine IGUANA (Marine Imaging of Galápagos Upwelling and the Neighboring Archipelago) project that deployed 53 broadband OBS instruments from R/V Langseth as part of cruise MGL2304. The goal of the project is to image the Galápagos mantle plume and its interaction with the Western Galápagos spreading center. The file presented here is in GMT-compatible netCDF grid format with a horizontal resolution of 100 m. Preliminary processing was done on the data using MB-System; additional processing could be done to correct some remaining issues. The raw Marine IGUANA multibeam data are available at: https://www.marine-geo.org/tools/search/entry.php?id=MGL2304. Funding was provided by National Science Foundation award OCE 19-28197.

Microseismicity catalog of Discovery transform fault, East Pacific Rise, 2008
Author(s): Gong, Jianhua; Fan, Wenyuan; Parnell-Turner, Ross
Description: This microseismicity catalog is derived from data retrieved from ocean-bottom seismometers deployed in 2008 as part of the Quebrada-Discovery-Gofar (QDG) Transform Fault Experiment. The data file is in ASCII text format. The first row is a column header that describes the content of the catalog: Earthquake origin time, latitude, longitude, depth and local magnitude. Not all earthquakes have a local magnitude estimate because of the selection criteria. Details of the earthquake location methodology and location interpretations can be found in the Geochemistry, Geophysics, Geosystems paper "Machine learning-based new earthquake catalog illuminates on-fault and off-fault seismicity patterns at the Discovery Transform Fault, East Pacific Rise". The data set was generated as part of the projects called Capturing 4D Variations in Stress, Slip, and Fault-Zone Material Properties: The 2019-2021 Gofar Transform Fault Earthquake Prediction Experiment; and, CAREER: Using seismic sources to probe megathrust fault conditions. The project was funded by NSF awards OCE-1833279 and EAR-2143413. DOI: 10.26022/IEDA/331304

Processed gravity data (netCDF format) at the Cocos-Nazca spreading center from cruise SR1806 (2018)
Author(s): Zheng, Tingting; Lin, Jian; Schouten, Hans; Smith, Deborah; Klein, Emily; Parnell-Turner, Ross
Description: Mantle Bouguer anomaly (MBA) was calculated by removing the gravitational effects of the water-crust and crust-mantle interfaces from the Free-air anomaly (FAA), assuming water, crust, and mantle densities of 1.03 × 10^3, 2.7 × 10^3, and 3.3 × 10^3 kg m^-3, respectively, and using a 6-km thick reference crust. Residual Mantle Bouguer anomaly (RMBA) was calculated by subtracting age-dependent thermal model from the MBA. The end-member model of the crustal thickness model here was calculated by the downward continuation of the RMBA to a depth of 10 km by assuming that the RMBA is controlled only by variations in crustal thickness. Free-air anomaly (FAA) was generated by combining the shipboard FAA data from cruise SR1806 with global satellite FAA data from Sandwell et al. (2014). The lithosphere cooling effect (i.e., thermal model) is estimated by assuming a 1-D half space plate cooling model. The data files are in GMT-compatible netCDF grid format. All data were gridded at 1-arc-second node spacing. The gravity calculation region is from 105°W to 95°W and 1°S to 5°N, but we suggest using data within 104°W to 96°W and 0 to 4°N to avoid boundary effects. This data set has a Zenodo DOI: https://doi.org/10.5281/zenodo.7590816.

Heat flow data from the Pythia's Oasis methane seep site, 2019 (AT42-17)
Author(s): Harris, Robert; Spinelli, Glenn
Description: Pythia's Oasis is a methane seep site 60 nautical miles offshore the coast of Oregon. This site is different from other seep sites. It hosts a discrete orifice that has continually vented low-salinity, hydrocarbon-bearing fluids since 2015 and was still active as of August of 2022. The site was discovered in 2015 during a Regional Cabled Array (RCA) Operations and Maintenance Cruise using hull-mounted sonar on R/V Thompson to detect methane bubble plumes in the water column. In 2019, in-situ measurements of thermal gradient and thermal conductivity were collected using the OSU 3.5-m violin-style heat flow probe. The thermistor string houses 11 thermistors and measures both the in-situ thermal gradient and thermal conductivity that are combined to determine the heat flow. On most measurements the probe position was determined with ultra-short baseline telemetry (USBL). The data was processed using SlugHeat (https://marine-heatflow.ceoas.oregonstate.edu/software/). The data file is in Excel spreadsheet format, with column headers. Funding was provided by National Science Foundation award OCE19-02446. DOI: 10.26022/IEDA/331300

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

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

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

Author(s): Parnell-Turner, Ross; Gee, Jeffrey; Berrios-Rivera, Natalia; Fornari, Daniel; McDermott, Jill; Barreyre, Thibaut
Description: Near-bottom magnetic data was collected at the East Pacific Rise, from 9°50'N, during a total of 20 AUV Sentry dives conducted from R/V Atlantis and R/V Roger Revelle during 2018 Atlantis cruise AT42-06 (three dives); 2019 Atlantis cruise AT42-21 (ten dives); and, 2021 Revelle cruise RR2102 (seven dives). Track lines were spaced 170 m apart, with Sentry about 70 m above bottom, collecting magnetic data using three Applied Physics Systems Model 1540 triaxial fluxgate magnetometers mounted on AUV Sentry. Sentry navigation was obtained using a 300 kHz Teledyne Doppler velocity log (DVL) and a Sonardyne AvTrak2 ultra-short baseline (USBL) acoustic positioning system, combined with an iXblue Phins inertial navigation system (INS), and a Paroscientific 8B7000-I Digiquartz depth sensor. The magnetic data are in ASCII text format, with one file each for top, port, and starboard magnetometers. Each ASCII file contains 11 columns, as follows: lon (degrees), lat (degrees), time (unix time, seconds), depth (m), altitude (m), roll (degrees), pitch (degrees), heading (degrees), X, Y, Z components of magnetic field strength (in oersted, i.e. x10^5 nT). Note that the magnetic data are X,Y,Z in sensor coordinates. The Sentry dive number and magnetometer mount point location is given in the file name. The three ASCII files for each dive correspond to one combined MATLAB file in an associated data set.

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

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

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

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

Sediment chemistry (GeoTIFF grid format) from surface carbon and nitrogen analysis of sediment grab samples, Long Island Sound mapping project Phase II
Author(s): Nitsche, Frank; Kenna, Timothy; McHugh, Cecilia
Description: Sediment grab samples were taken in summer of 2017 and 2018 using a modified van Veen grab sampler. A sub-sample of the top two centimeters was stored in a jar. Dried and homogenized splits of the samples were sent to the Cornell Isotope Laboratory (COIL) to be analyzed for carbon and nitrogen concentrations as well as stable isotopic compositions. Total carbon (TC), total nitrogen (TN), and δ15N were determined on an aliquot of untreated, dried homogenized sediments. In order to accurately determine total organic carbon (TOC) and δ13C, removal of carbonate is necessary. This was achieved through sequential treatments of the sediments with dilute hydrochloric acid until no bubbling was observed. The acidified sediments were then rinsed in deionized water and re-dried. In the Cornell Lab the samples were analyzed using a NC2500 elemental analyzer interfaced with a Thermo Delta V isotope ratio mass spectrometer (IRMS). ArcGIS Pro empirical kriging has been used to interpolate values for organic carbon, total carbon, nitrogen, d13C and d15N isotope content onto a 50 m raster. The interpolated raster has been clipped to fit the extent of the phase 2 survey area. The final raster data files are in GeoTIFF grid format with UTM-18 N projection.Funding was provided by the Long Island Sound Mapping Fund administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).

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

LIS Phase II seafloor mapping: Sidescan images (GeoTIFF format), eastern Long Island Sound (2017-18)
Author(s): Flood, Roger
Description: Seafloor sidescan data provides important information on water depth and on the character of features on the seafloor to improve our understanding of benthic habitat. Sidescan and multibeam sonar data was collected in 2017-2018 during field surveys by SoMAS, Stony Brook University, in eastern Long Island Sound as part of the Phase 2 of the Long Island Sound Cable Fund Benthic Habitat Mapping Project. The sidescan files in this data set are in GeoTIFF image format and cover 10 of the 27 Survey Blocks assigned to SoMAS. The values of sidescan acoustic backscatter reported in these images depends somewhat on the equipment used and the computer processing that is done in creating the backscatter images. Acoustic backscatter data recorded depends on the azimuth of the sonar track so the final images tried to keep acoustic data collected in a similar orientation. The sidescan sonar data was collected with a pole-mounted system and there was some small across-track amplitude variation due to the instrument roll and there are some residual along-track amplitude variations related to the sonar beam pattern. Although no quantitative analysis was done, the sidescan backscatter data reported during this project is qualitatively similar to that reported by NOAA in NCEI Dataset 0167531 when the image DN values are appropriately stretched. The data is not to be used for navigation. The sidescan field surveys were performed in December 2017 to March 2018 (file names DM). The data was collected on the SoMAS Research Vessel Donald W Pritchard using a pole-mounted EdgeTech 272-TD system which was operated at 100 kHz. All field programs used an Applanix motion sensor system for vessel motion and heading, GPS positions corrected using data from the ACORN RTN (UConn) system, vessel elevations determined using GPS RTN elevations supplemented by scaled and offset land-based water-level measurements, and sound velocity profiles collected using an AML BASEX probe. The sidescan data was recorded in xtf format and processed using programs in the SwathEd program suite developed at the University of New Brunswick (UNB) with modifications done at Stony Brook University. The sonar position, altitude and orientation (heading, roll and pitch) were merged with the sonar data using values recorded by the multimbeam system operating at the same time. The xtf files where re-written with updated sonar navigation, altitude, heading, roll and pitch and those files have been archived. A slant-range correction was made assuming a flat sea floor and the sonar values were plotted on a 1 m grid but only the data closest to a ship track was plotted. The ship tracks used in the mosaic were selected to have consistent orientations and to avoid crossing lines. A correction was applied to the sidescan sonar data based on fish height and slant range to correct signal levels for sonar beam pattern, attenuation and angle-of-incidence but some along-track signal anomalies exist in the map grids. The final maps were made using the corrected signal levels. No correction was made for instrument roll and there is some striping in the sonar mosaics because of the sonar roll. The 8-bit sonar mosaics were imported to ArcMap as tif files and exported as georeferenced GeoTIFFs. Horizontal positions are accurate to about 1 m. The data files show the conditions at the time of the survey in 2017-2018. The full suite of SoMAS mapping comprises four components: multibeam bathymetry (26 maps), bathymetry hillshade (26 maps), multibeam backscatter (26 maps), and sidescan sonar backscatter (9 maps), for a total of 87 maps. The multibeam bathymetry and backscatter data were integrated by NOAA into project-wide maps that can be found at NCEI (Dataset 0167531 version 2.2, https://doi.org/10.25921/tgp1-w632).

LIS Phase II seafloor mapping: Acoustic Backscatter images (GeoTIFF format), eastern Long Island Sound (2017-18)
Author(s): Flood, Roger
Description: Seafloor bathymetry and acoustic backscatter data provides important information on water depth and on the character of features on the seafloor to improve our understanding of benthic habitat. Multibeam sonar data was collected in 2017-2018 during field surveys by SoMAS, Stony Brook University, in eastern Long Island Sound as part of the Phase 2 of the Long Island Sound Cable Fund Benthic Habitat Mapping Project. The acoustic backscatter files in this data set are in GeoTIFF image format and cover the 27 Survey Blocks assigned to SoMAS plus a site in deeper water (Barchans). The backscatter images were created using the program QPS FMGT using multibeam track lines that had been edited and processed by CARIS HIPS and SIPS. The program corrects the sonar data to remove cross-track variations in signal levels. Two different multibeam systems were used to collect the data reported for this study and the data values from the two systems were compared in areas where data sets overlapped. The results from the EM3000D survey were offset and scaled so that the backscatter distributions in the overlap areas were similar. 8-bit multibeam backscatter grids were exported as GeoTIFF images. For all the images reported, higher backscatter values are shown in a lighter color and lower backscatter are shown in a darker color. The 2017-2018 SoMAS surveys have few gaps except for 13_JJ (a compilation of transit tracks that overlap the grid 13_DM) and Barchans (lines that image barchan dunes that are migrating across the seafloor). The data is not to be used for navigation. The field surveys were performed in December 2017 to March 2018 (file names DM) and June-July 2018 (file names JJ). The data was collected on the SoMAS Research Vessel Donald W Pritchard using an EM3000D echo-sounder for the surveys from December, 2017 through March, 2018, and using an EM2040cD (dual-head) echo-sounderfor data collected in June and July, 2018. All field programs used an Applanix motion sensor system for vessel motion and heading, GPS positions corrected using data from the ACORN RTN (UConn) system, vessel elevations determined using GPS RTN elevations supplemented by scaled and offset land-based water-level measurements, and sound velocity profiles collected using an AML BASEX probe. Bathymetry data was processed using CARIS HIPS and SIPS (version 10.4). Data points were edited to remove spurious bed elevations and sound-velocity refraction corrections were applied. Data values were gridded at 1 m horizontal resolution using the Swath Angle gridding algorithm into a series of 26 base maps (resolution is 2 m for the 2018 Barchans file). The 32-bit GeoTIFF gridded base maps are projected in NAD_1983_2011_UTM_Zone_18N and seafloor elevations are reported in meters relative to NAVD-88. Vertical elevations are accurate to about 0.1 to 0.2 m. Elevations may be less accurate at the outer edges of the swath where refraction artifacts can occur. Horizontal positions are accurate to about 1 m. The data files show the conditions at the time of the survey in 2017-2018. The full suite of SoMAS mapping comprises four components: multibeam bathymetry (26 maps), bathymetry hillshade (26 maps), multibeam backscatter (26 maps), and sidescan sonar backscatter (9 maps), for a total of 87 maps.

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. DOI: 10.26022/IEDA/331159

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. DOI: 10.26022/IEDA/331158

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.

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. 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?

The AUV Sentry magnetometer is an APS (Applied Physics Systems) model 1540 3-axis fluxgate sensor (https://www.appliedphysics.com/products/magnetometers/). AUV Sentry has three magnetometer sensors, two are located mid-body on the port and starboard side and one is located in the top of the vehicle. These data files contain raw magnetic field data from the 'top' sensor which is also identified as the '02' sensor. Navigation is by USBL.The data files are in ASCII format with the following columns: year, month, day, hour, min, sec, latitude (dec. degrees), longitude (dec. degrees), depth (meters), pressure (decibars), heading (degrees), altitude (meters), mag02x (nT), mag02y (nT), mag02z (nT), optical backscatter sensor OBS (volts), redox potential eh (volts), rate of change of redox potential dehdt (volts/second), oxygen O2 (micromolar), temperature (celsius), conductivity (siemens/meter), sound speed (meters/second), sound velocity profile SVP (meters/second), oxygen reduction potential (volts). The data set was collected under grant OCE13-56839 from the National Science Foundation. The AUV Sentry magnetic data were analyzed and interpreted under a Woods Hole Oceanographic Institution (WHOI) internal research grant to Maurice Tivey and with additional support for Bailey Fluegel by the WHOI Summer Student Fellow program in 2021. The data set is described in Fluegel et al., GRL, 2022. DOI: 10.26022/IEDA/331045

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

Processed seismic profiles 02, 11, and 15 (SEG-Y 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 data files presented here are in SEG-Y format. Processing of these data comprised trace-editing, simple frequency filtering (10-500 Hz), suppression of a receiver-ghost signal by predictive deconvolution, surface-related multiple elimination as well as spherical divergence correction, pre-stack time migration followed by top-muting and white-noise removal. These data have a main frequency of 60 Hz indicating a vertical resolution of approx. 8-15 m.This processed seismic data set is interpreted in Preine et al., Tectonics, 2022. The study was funded with German Research Foundation DFG grant HU690/25-1. DOI: 10.26022/IEDA/331028

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

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 data 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 data files are in SEG-Y format and 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. Navigation in the header is in arc minmutes with a scaler of 10,000. For conversion to decimal degrees, divide navigation values by 600,000. Gas throughout the data set disrupts the signal. Funding was provided by the Delta Stewardship Council Delta Science Program under Grant #1167. DOI: 10.26022/IEDA/330931

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

Description: This ASCII CSV file provides raw lake floor horizon and bathymetry data 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 a., 2011 for specific information on primary data. The file contains six columns: UTM X (meters), UTM Y (meters), latitude (degrees), Longitude (degrees), Lake Floor Elevation above sea level (m), Depth below lake surface (meters). The UTM values are in UTM zone 36 S. DOI: 10.26022/IEDA/330929

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.

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 (GeoTIFF image 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. This raster data file is in GeoTIFF image format in the geographic WGS-1984 coordinate system and has 1-m horizontal resolution, with square cells for use with GIS. The GeoTIFF image is slope-shaded using the Haxby color ramp with the depth range that was used in Figure 1 of LeSaout et al., 2021: -2600 to -2000 meters. Funding for the work was provided through annual grants to MBARI from the David and Lucile Packard Foundation. DOI: 10.26022/IEDA/330467

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

Mission Parameter Files and Documentation for GNSS-A data in Cascadia
Author(s): Chadwell, C., David; Schmidt, David
Description: These data were collected as part of GNSS-A operations on the Cascadia Subduction Zone, and can provide estimates of crustal deformation rates along the plate boundary. The data were collected on missions starting in 2016 by a remotely-operated Wave Glider system. The Wave Glider collects GNSS data while ranging to an array of seafloor transponders. All of the GNSS-A sites are located on the accretionary prism. These files provide the site coordinates, transponder IDs, Wave Glider transducer-antenna offsets, sensor models, file descriptions, and other documentation related to a Wave Glider mission and GNSS-A site. The file names identify the site, year and Wave Glider ID. The data files were generated with NSF funding as part of the projects called Constraining Slip Distribution of the Cascadia Subduction Zone Offshore Central Oregon with Seafloor Geodesy; and, Assessing the State of Locking on the Frontal Thrust of the Cascadia Subduction Zone With Seafloor Geodesy.

The original CTD data files were acquired during UNOLS cruises AT26-20 (2014) and RR1808 (2018), when the seafloor transponder arrays were first deployed. The data files presented here are derived from those CTD data, are in ASCII format and provide processed sound velocity data near each GNSS-A array. The file names identify the site and crusie ID. The data files were generated with NSF funding as part of the projects called Constraining Slip Distribution of the Cascadia Subduction Zone Offshore Central Oregon with Seafloor Geodesy; and, Assessing the State of Locking on the Frontal Thrust of the Cascadia Subduction Zone With Seafloor Geodesy.

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).

Processed bathymetry (GeoTIFF grid format raster images) derived from Geoswath multibeam data 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 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. 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 acquired bathymetry data were processed using CARIS software. The data were acquired and processed in two individual blocks. The final bathymetry grids are in GeoTIFF (Raster) grid format, projected in WGS84 UTM 18N (EPSG: 32618) with 1m resolution. 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.

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
