All information provided by GEBCO on its web pages is made available to provide immediate access for the convenience of interested persons. Whilst GEBCO believes the information to be reliable, human or mechanical error remains a possibility.

GEBCO is essentially a deep ocean product and does not include detailed bathymetry for shallow shelf waters. Even to the present day, most areas of the world’s oceans have not been fully surveyed and, for the most part, bathymetric mapping is an interpretation based on random tracklines of data from many different sources. The quality and coverage of data from these sources is highly variable. Although the GEBCO grid is presented at one minute intervals of latitude and longitude, this does not imply that knowledge is available on sea floor depth at this resolution - the depth in most one minute squares of the world’s oceans has yet to be measured.
GEBCO's data sets are not to be used for navigation or for any purpose relating to safety at sea.
