Data Management at NCEI


The NOAA National Centers for Environmental Information (NCEI) are part of the US Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), National Environmental Satellite, Data, and Information Service (NESDIS).

NCEI's mission with regard to Marine Geology and 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.

NCEI 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.
