The General Bathymetric Chart of the Oceans (GEBCO) aims to provide the most authoritative, publicly-available bathymetry data sets for the world’s oceans.


GEBCO consists of an international group of experts who work on the development of a range of bathymetric data sets and data products, including gridded bathymetric data sets, a world map and Gazetteer of Undersea Feature Names.

We are involved in training a new generation of scientists in ocean bathymetry through the Nippon Foundation/GEBCO Training Programme. To get involved in GEBCO please contact us.

GEBCO operates under the auspices of the International Hydrographic Organization (IHO) and the Intergovernmental Oceanographic Commission (IOC) of UNESCO.
