We are continually working to update and improve our global bathymetric grid. This is only possible through access to data sets and regional bathymetric compilations made available by the international community. We thank all data contributors.
Even to this day large areas of the global ocean floor have not been mapped using modern echo-sounding techniques. Help us to map the gaps, find out how to contribute your data and get involved in GEBCO.
The GEBCO grid has been built from data from a number of sources, including regional and global grids and hundreds of individual surveys made available through international and national databases such as the IHO Data Center for Digital Bathymetry (IHO-DCDB) and from partners in industry.
The table below lists the data contributions included in the GEBCO_2021. An updated list to include data sets included in the 2022 Grid will be available shortly.
