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 data sets comprise two global gridded bathymetric data sets, the GEBCO_08 Grid and GEBCO One Minute Grid and a global set of digital bathymetric contours, coastlines, trackline control information. The data sets are maintained and updated 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.
