key figures

3800 metres is the average depth of the ocean, but it reaches 11,020 metres in the Mariana Trench in the northwestern part of the Pacific Ocean (coordinates 11° 21′ North Latitude and 142° 12′ East Longitude).

The GEBCO World Map shows the bathymetry of the world’s ocean floor in a shaded relief colour map. This version is an updated version of the 2013 world map (second version). It now includes the names of the underwater features.

Work to create the GEBCO global map began as a Nippon Foundation/GEBCO Training Project laboratory workshop at the Centre for Coastal and Ocean Mapping at the University of New Hampshire, USA.
