Marine Geoscience Data System (MGDS)

The Marine Geoscience Data System (MGDS), part of the Integrated Earth Data Applications (IEDA) facility, provides access to data portals for the NSF-supported Ridge 2000MARGINS, and GeoPRISMS programs, the Antarctic and Southern Ocean Data Synthesis, the Global Multi-Resolution Topography Synthesis, and Seismic Reflection Field Data Portal. These portals were developed and are maintained as a single integrated system, providing free public access to a wide variety of primarily marine geoscience data collected during expeditions throughout the global oceans.

The MGDS expedition catalog and data repository is powered by a relational database, which can be queried through web-based keyword and map searches, and is accessible through web services that follow the specifications of the Open Geospatial Consortium (OGC).

The MGDS's 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.
