title: Near-bottom AUV Sentry processed bathymetry grids (netCDF format) from the Pythia's Oasis methane seep site

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 grids presented here are in GMT-compatible netCDF format and the resolution is given in the file name. Funding was provided by National Science Foundation award OCE16-58201.

title: Near-bottom ROV multibeam bathymetry grid (netCDF format) from the Octopus Garden hydrothermal spring site

description: Near-bottom high-resolution bathymetry data were collected with a Reson 7125 multibeam sonar that is part of the MBARI Low Altitude Survey System (LASS) mounted for two dives in 2021 to the ROV Doc Ricketts, which was flown at 3 m altitude at speeds &lt;= 1.0 m/s to produce 5 cm-resolution bathymetry grids and images from the multibeam. The grid file presented here is in GMT-compatible netCDF format and the projection is UTM zone 10N. Position and attitude data were provided by a Kearfott SeaDevil Inertial Navigation System (INS) integrated with a 1200 kHz Teledyne RD Instruments Doppler velocity log (DVL) and a Paroscientific pressure sensor. The LASS sensor package was mounted in an articulating frame within an ROV tool sled that rotates from pointing the sensors vertically down to horizontally forward, allowing surveys of flat to vertical seafloor. The articulation is automated by closing a control loop around the difference between the forward and backward beams of the DVL. Funding was provided by a grant from the David and Lucile Packard Foundation to MBARI.

title: Gridded bathymetry data from Galapagos Marine IGUANA OBS deployment cruise MGL2304 (2023)

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.

title: Microseismicity catalog of Discovery transform fault, East Pacific Rise, 2008

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.
