The U.S. National Geophysical Data Center (NGDC), collocated with the World Data Center A for Marine Geology and Geophysics and the International Hydrographic Organization (IHO) Data Center for Digital Bathymetry, operates and maintains several large bathymetric databases. These include the National Oceanic and Atmospheric Administration's (NOAA) National Ocean Service Hydrographic Database (NOSHDB), the global marine geophysical database, and a multibeam bathymetric database. In addition, some gridded data sets derived from original data are available from NGDC. Data are provided on various forms of magnetic media, on compact discs (CD‐ROM), and also through the internet network via anonymous file transfer protocol. Improved data access and retrieval is one of NGDC's priorities.
