Copying of the data in the GEBCO Digital Atlas in digital form for dissemination to third parties is prohibited without prior written permission from the British Oceanographic Data Centre. The price of the GEBCO Digital Atlas has been deliberately set at a low level so as to encourage users to purchase their own copies.

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 (email BODC Enquiries) 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 the GEBCO Digital Atlas.

The legal copyright of the main components of the GEBCO Digital Atlas is held by the UK Natural Environment Research Council (NERC) on behalf of the Intergovernmental Oceanographic Commission (IOC) of UNESCO and the International Hydrographic Organization (IHO), through the Joint IOC/IHO Guiding Committee for GEBCO.

The legal copyright of certain components is held separately

NERC does not hold the copyright of the World Vector Shoreline; the International Bathymetric Chart of the Arctic Ocean (IBCAO) bathymetry; the Global Land One-km Base Elevation (GLOBE) land elevation data or of the US National Geophysical Data Center's Geophysical Data System (GEODAS) trackline inventory.

Any material reproduced from the GEBCO Digital Atlas should be accompanied by appropriate attribution to the source of the material. For non GEBCO material, such as the Coastline of Antarctica, acknowledgement should include reference to the original source (the ICSU Scientific Committee on Antarctic Research).

If the GEBCO bathymetry is being downgraded or is being reproduced over a large area covering many sheets then the source should be acknowledged as 'The GEBCO Digital Atlas published by the British Oceanographic Data Centre on behalf of IOC and IHO, 2003'.

If the bathymetry is being reproduced in its original form for a specific region then the acknowledgement should include reference to the scientific coordinators responsible for compiling the original contours, for example: 'The bathymetry is reproduced from GEBCO Sheet G.08 compiled by R.L. Fisher of the Scripps Institution of Oceanography and extracted from the GEBCO Digital Atlas published by the British Oceanographic Data Centre on behalf of the IOC and IHO, 2003’.

Correct citation for this publication: IOC, IHO and BODC, 2003, "Centenary Edition of the GEBCO Digital Atlas", published on CD-ROM on behalf of the Intergovernmental Oceanographic Commission and the International Hydrographic Organization as part of the General Bathymetric Chart of the Oceans; British Oceanographic Data Centre, Liverpool.

Disclaimer

Information in the GEBCO Digital Atlas has been obtained from sources believed to be reliable but its accuracy and completeness cannot be guaranteed. Whilst every effort has been made to ensure its reliability within the limits of present knowledge, no responsibility can be accepted by those involved in its compilation or publication for any consequential loss or damage arising from its use.

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.

THE GEBCO DIGITAL ATLAS IS NOT TO BE USED FOR NAVIGATION OR FOR ANY OTHER PURPOSE RELATING TO SAFETY AT SEA.
