The NOAA National Centers for Environmental Information (formerly the National Geophysical Data Center) provide scientific stewardship, products and services for sea floor and lakebed data, including geophysics (gravity, magnetics, seismic reflection, bathymetry, water column sonar), and data derived from sediment and rock samples.
NCEI compiles coastal and global digital elevation models, high-resolution models for tsunami inundation studies, provides stewardship for NOS data supporting charts and navigation, and is the US national long-term archive for MGG data
World Data Service for Geophysics is covered by Thomson Reuters Data Citation Index. === NOAA’s former three data centers—the National Climatic Data Center, the National Geophysical Data Center, and the National Oceanographic Data Center, which includes the National Coastal Data Development Center—have merged into the National Centers for Environmental Information (NCEI). === Effective October 2011, the World Data Service for Geophysics, collocated at NCEI, replaces former World Data Center for Geophysics and Marine Geology, and for Solar-Terrestrial Physics. === World Data Service for Geophysics is part of ICSU World Data System. === NCEI (formerly NGDC) is the national long-term archive for data and metadata pertaining to underway geophysical data and marine geological samples collected with US National Science Foundation (NSF) funds. This role is outlined in NSF11060 Policy for Oceanographic Data. ===
