News and events — April 2013
The second release of the GEBCO world map is now available. It shows the bathymetry of the world's ocean floor in the form of a shaded relief colour map.

Creation of the map
The map is based upon bathymetry data from the GEBCO_08 Grid, version 20100927, a global bathymetric grid with 30 arc-second spacing.
Work on the development of the GEBCO world map began as a laboratory workshop project of the Nippon Foundation/GEBCO Training Project at the Center for Coastal and Ocean Mapping of the University of New Hampshire, USA.
