BODC maintain and make available global bathymetric data sets on behalf of the General Bathymetric Chart of the Oceans (GEBCO) community.

GEBCO have released version 20100927 of the GEBCO_08 Grid — a global bathymetric grid with 30 arc-second spacing. It includes new bathymetric compilations for the Black Sea, Caspian Sea and Weddell Sea regions. This is now available for download alongside the GEBCO_08 Source Identifier and GEBCO One Minute Grids. Users have the option of downloading the complete netCDF grid file(s) or a file covering a user-defined area.

More about the GEBCO_08 Grid

The GEBCO_08 Grid was generated by combining quality-controlled ship depth soundings with interpolation between sounding points guided by satellite-derived gravity data. It is a continuous terrain model for ocean and land with the land data largely derived from the Shuttle Radar Topography Mission (SRTM30) data set.
