The Marine Geoscience Data System (MGDS) provides a suite of tools and services for free public access to marine geoscience research data acquired throughout the global oceans and adjoining continental margins. The system evolved from projects initiated from 2003-2004 with funding from the National Science Foundation to provide data management services for the U.S. Antarctic Program (USAP), the Ridge 2000 and MARGINS programs, and for active source seismic data. In 2005, the system was expanded to include dedicated data management services for global bathymetry data. Since 2010, MGDS has been part of IEDA, an NSF-funded data facility for solid earth geoscience data.
Data Systems & Services
- The Marine-Geo Digital Library is an interactive digital data repository and metadata catalog that offers a suite of services for data discovery and preservation. The Marine-Geo Digital Library currently provides open web-based access to 53.1TB of data, corresponding to over 617,000 digital data files from more than 2,620 research programs dating back to the 1970’s. The repository can be accessed through a geospatially enabled search interface and map-based data explorer, and is accessible through web services that follow the specifications of the Open Geospatial Consortium (OGC). The Marine-Geo Digital Library offers data preservation services including long-term archiving, the registration of data with DOIs® for persistent identification and formal citation, and links to related scholarly publications. The Marine-Geo Digital Library provides reports summarizing data download activity to all contributing investigators twice annually. Data can be contributed to the Marine-Geo Digital Library online or by contacting us.
Community Data Portals - MGDS provides Community Data Portals for several NSF-supported research programs and facilities based on disciplinary and programmatic themes. Each portal provides custom resources and access to comprehensive data collections assembled for each community. Data Portals are available for the GeoPRISMS, MARGINS, and Ridge 2000 research initiatives, the Academic Seismic Portal ASP@LDEO and ASP@UTIG collections supporting marine seismic research, the GMRT synthesis of global bathymetry, a collection of submersible data, and a newly initiated Coastal data collection.
Antarctic Data Resources - MGDS hosts the Antarctic and Southern Ocean Data Synthesis collection of data from research vessels of the US Antarctic Program. We also host the US Antarctic Program Data Center (USAP-DC), which provides tools to help scientists find Antarctic data of interest and satisfy their obligation to share data under the NSF Division of Polar Programs (PLR) data policy. MGDS is a founding member of the Antarctic & Arctic Data Consortium.
Global Bathymetry - Our Global Multi-Resolution Topography (GMRT) synthesis is a continuously-updated compilation of seafloor swath bathymetry integrated with global land topography. Swath bathymetry data acquired with ships throughout the global oceans are cleaned, quality assured and curated by the our data managers for inclusion in GMRT. Custom maps and grids can be created using the GMRT MapTool and the synthesis can be accessed through several standard programmatic interfaces including GeoMapApp and Google Earth.
Visualization and Analysis Tools - GeoMapApp, a standalone tool developed by MGDS, permits dynamic data exploration and analysis from a map interface and provides access to a broad range of geoscience data from the marine and terrestrial environments. GeoMapApp allows users to access and interact with hundreds of gridded and tabular data sets without needing specialist knowledge of file formats and software tools. A suite of portals provides custom tools for accessing and visualizing global collections of specialized data sets including gravity and magnetics trackline data, seismic reflection profiles, earthquake locations, seafloor bedrock geochemistry from PetDB, and sediment information from ocean drilling. Options are also available for users to import their own data tables and grids and make custom maps. Other MGDS visualization tools include Virtual Ocean, a 3D virtual globe application which integrates the GeoMapApp tool suite with the NASA World Wind 3-D earth browser and our data browser Marine-Geo Explorer.
