The source should be acknowledged as 'Reproduced from the GEBCO Digital Atlas published by the British Oceanographic Data Centre on behalf of IOC and IHO, 2003'. The production of the GEBCO Digital Atlas is the culmination of a community based endeavour involving numerous scientists and hydrographers across the world who have devoted much of their time and effort, often on a voluntary basis. For the most part, this endeavour was stimulated by a wish to create an authoritative, high quality bathymetry of the world's oceans for the benefit of humanity. The GEBCO community does not wish the contents of the GEBCO Digital Atlas, either in whole or in part, to be used for commercial gain and requests that any monies accruing from sales of the GDA CDROM set should be reinvested in the further development of GEBCO. Copying of the data from the GEBCO Digital Atlas in digital form for dissemination to third parties is prohibited without prior written permission from the British Oceanographic Data Centre. Reproduction for resale or for use in a commercial product or for any other commercial purpose is prohibited without the prior written permission of the copyright holders. In the first instance, any request for such permission should be addressed to the British Oceanographic Data Centre and should include a clear statement of the purpose for which the material will be used and the manner in which it will be reproduced. In the case of commercial activities, consideration will always be given to the possibility of making an appropriate charge, the benefits from which will be used for the further development of GEBCO.

Statement

The GEBCO One Minute Grid is an ArcInfo Grid version of the original data source gridone.grd NetCDF file.

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 seafloor depth at this resolution - the depth in most one minute squares of the world's oceans has yet to be measured.
