Use our application to select and download data in netCDF, Esri ASCII raster and data GeoTiff formats.
If the data sets are used in a presentation or publication then we ask that you acknowledge the source.This should be of the form:
The GEBCO Grid is placed in the public domain and may be used free of charge. Use of the GEBCO Grid indicates that the user accepts the conditions of use and disclaimer information.
Although every care is taken during the development of the GEBCO bathymetric grids, errors can occasionally occur, and can be reported to the Seabed 2030 Global Centre (). Known issues can be viewed on our errata pages.
GEBCO's global elevation models are generated by the assimilation of heterogeneous data types assuming all of them to be referred to mean sea level. However, in some shallow water areas, the grids include data from sources having a vertical datum other than mean sea level. We are working to understand how best to fully assimilate these data.
