Data Management at NGDC
NGDC organizational diagram
Marine geological and geophysical data at the National Geophysical Data Center are managed by the MGG Division.
The National Geophysical Data Center is part of the US Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), National Environmental Satellite, Data, and Information Service (NESDIS). NGDC is one of three NOAA National Data Centers (NNDC).
NGDC's mission with regard to Marine Geology & Geophysics (MGG) is data management in the broadest sense, playing a role in the nation's research into the environment and providing data to a wide group of users.
NGDC is responsible for stewardship, archival, and dissemination of geological and geophysical data from the global sea floor and lakebeds.
Data are compiled from both national and international sources through cooperative programs and exchange agreements, including through the World Data Center system.
Guidelines for Contributing MGG Data
National Cooperative Activities
NGDC is the data management lead for US exploration of potential extended continental shelf (ECS) areas, creates high-resolution digital elevation models in support of tsunami inundation studies, stewards NOS data in support of charting and navigation, and is the US National long-term archive for marine geological and geophysical data collected with US public funds.
International Cooperative Activities
In addition to operating the World Data Service for Geophysics, NGDC also operates the International Hydrographic Organization Data Center for Digital Bathymetry (IHO DCDB) on behalf of the Member Nations of the International Hydrographic Organization, and participates in many international projects and organizations.
