Repository providing free access to marine geophysical data (e.g. bathymetry, seismic data, magnetics, gravity, images) and related land-based data from NSF-funded research conducted throughout the global oceans. Data Portals include GeoPRISMS, MARGINS, Ridge 2000, Antarctic and Southern Ocean Data Synthesis, the Global Multi-Resolution Topography Synthesis, and Seismic Reflection Field Data Portal. Primary data types served are multibeam bathymetric data from the ocean floor, seismic reflection data imaging below the seafloor, and multi-disciplinary ship based data from the Southern Ocean. Other holdings include deep-sea photographic transects, and ultra-high resolution bathymetry, temperature probe data, biological species compilations, MAPR and CTD data. Derived data products and sets include microseismicity catalogs, images, visualization scenes, magnetic and gravity compilations, grids of seismic layer thickness, velocity models, GIS project files, and 3D visualizations. Tools to discover, explore, and visualize data are available. They deliver catalogs, maps, and data through standard programmatic interfaces. GeoMapApp, a standalone data visualization and analysis tool, permits dynamic data exploration from a map interface and the capability to generate and download custom grids and maps and other data. Through GeoMapApp, users can access data hosted at the MGDS, at other data repositories, and import their own data sets. Global Multi-Resolution Topography (GMRT) is a continuously-updated compilation of seafloor bathymetry integrated with global land topography. It can be used to create maps and grids and it can be accessed through several standard programmatic interfaces including GeoMapApp and Google Earth. The GMRT compilation can also be explored in 3D using Virtual Ocean. The MGDS MediaBank contains high quality images, illustrations, animations and video clips that are organized into galleries. Media can be sorted by category, and keyword and map-based search options are provided. Each item in the MediaBank is accompanied by metadata that provides access to a cruise catalog and data repository.

This dataset contains biological specimens sampled at the seafloor, taken from NSF Ridge2000 expeditions.

This data set is the correlation-based, double-difference processed earthquake catalog derived from ocean bottom seismometers (OBS) deployed at the East Pacific Rise between October 2003 and April 2004. The data is in ASCII format and is described in detail in Waldhauser and Tolstoy, 2011 (see also Tolstoy et al., 2008 for an earlier, preliminary version of the catalog). The earthquake catalog was generated as part of the project called Seismic Monitoring of the 9N East Pacific Rise RIDGE 2000 Integrated Studies Site. Funding was from NSF grant OCE03-27283.

This data set contains the Marine Geoscience Data System (MGD77) data set from the Nathaniel B. Palmer (NBP) data acquisition system onboard the 2003 SBI Survey Cruise. The data set is divided into daily files in a space delimited columnar format. Data are in one-second time intervals and consist of various measurements taken aboard the ship.

The U.S. Geological Survey (USGS) mapped approximately 22 square miles of the Madison Swanson Marine Protected Area (MPA) and Steamboat Lumps MPA, which are located on the Florida shelf edge in the northeastern Gulf of Mexico in 2000 using sidescan sonar and high-resolution chirp seismic-reflection systems. This survey was conducted as part of a larger study of the effectiveness of no-fishing reserves in protecting grouper spawning aggregations. Field activity information for this cruise is available on-line through the U.S. Geological Survey Coastal and Marine Geoscience Data System at https://cmgds.marine.usgs.gov/fan_info.php?fa=2000-005-FA.

The dataset includes scanned seismic records collected during cruise 9209 of the RV Maurice Ewing (1992) using the Krupp-Atlas Hydrosweep sub-bottom echo-sounder (3.5 kHz). The dataset is composed both of the raw scanned images and processed scanned images. Seismic records were provided to the author of this work by the Lamont Doherty Earth Observatory (Earth Institute, Columbia University, USA). Processed ship-based Navigation Data acquired during the Maurice Ewing expedition EW9209 (1992) can be downloaded from the Marine Geoscience Data System: http://www.marine-geo.org/tools/search/Files.php?data_set_uid=11449

This database contains a comprehensive inventory of geologic (coral, coral reef, limestone, and sediment) cores and samples collected, analyzed, published, and/or archived by, or in collaboration with, the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC). The SPCMSC Geologic Core and Sample Database includes geologic cores and samples collected beginning in the 1970s to present day, from study sites across the world. This database captures metadata about samples throughout the USGS Science Data Lifecycle: including field collection, laboratory analysis, publication of research, and archival or deaccession. For more information about the USGS Science Data Lifecycle, see USGS Open-File Report 2013-1265 (https://doi.org/10.3133/ofr20131265). The SPCMSC Geologic Core and Sample Database also includes storage locations for physical samples and cores archived in a repository (USGS SPCMSC or elsewhere, if known). The majority of the samples and cores in this database come from field activities associated with the SPCMSC and have been assigned a field activity number (FAN) in the field activity management and data inventory tool for USGS Coastal and Marine Hazards and Resources Program (CMHRP) Coastal and Marine Geoscience Data System (CMGDS), https://cmgds.marine.usgs.gov/. Some cores and samples were retroactively assigned FANs based on existing metadata and published information. Cores and samples without FANs indicate there is insufficient information regarding collection of the core(s) or sample(s) needed in order to assign a field activity number in CMGDS. Please see the supplemental information section of the metadata for more information about FANs. All samples and cores contained in this database are described in published research. The database contains a link to the FAN page within the CMGDS for each sample or core where associated publications can be accessed. For a complete list of fields used in this database, please refer to the entity and attribute information section of this metadata record.

Example SU processing scripts and USGS software for viewing the SEG Y files (Zihlman, 1992) are also provided. These data are available for viewing using GeoMapApp (http://www.geomapapp.org/) and Virtual Ocean (http://www.virtualocean.org/) multi-platform open source software.
