Archive of historical GEBCO charts

Imagery from the 2nd Edition of the GEBCO chart series published between 1910 and 1930

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 GEBCO chart archive is available to view online from the International Hydrographic Organization's web site.

Further information about GEBCO's history and the history of seafloor mapping during the 20th Century can be found in the History of GEBCO book.
