General Bathymetric Chart of the Oceans (GEBCO)
GEBCO's aim is to provide the most authoritative, publicly-available bathymetry for the world's oceans. It operates under the joint auspices of the Intergovernmental Oceanographic Commission (IOC) and the International Hydrographic Organization (IHO).
GEBCO's bathymetric data sets comprise of global gridded bathymetric data sets and a global set of digital bathymetric contours. The data sets are maintained and updated on behalf of GEBCO at BODC.
GEBCO's grids are available to download from the internet. The full set of GEBCO's data sets are included in the GEBCO Digital Atlas (GDA) along with accompanying documentation and a software interface for viewing and accessing the data sets.
