Mapping the global seafloor

The oceans cover more than two thirds of the world's surface yet it is often said that we know more about the shape of the surface of Mars than we do about that of our global seafloor.

Read 'Understanding oceans' in the UNESCO Courier, Apr-Jun 2017, pages 65 - 69; by Vice Admiral (Rtd.) Shin Tani, Chairman GEBCO Guiding Committee, on why we need to map the seafloor.

GEBCO's aim is to provide the most authoritative publicly-available bathymetry of the world's oceans. It operates under the joint auspices of the International Hydrographic Organization (IHO) and the Intergovernmental Oceanographic Commission (IOC) (of UNESCO).
