News and Events — October 2017

The GEBCO chart series was initiated in 1903 by Prince Albert I of Monaco - providing information on the shape and depth of the global seafloor.

Through the 20th Century, there were five paper editions of the charts series before GEBCO released its first digital products in the early 1990s.

The historical GEBCO paper chart series archive is now available to view online from the International Hydrographic Organization's web site.
