We have recently updated our GEBCO grid download application. It still gives access to GEBCO's grids and allows download of the data in a number of formats but it now also gives access to grids at multiple resolutions.
Nominations are being sought for the 23rd course of the Nippon Foundation / GEBCO Training Program leading to a Graduate Certificate in Ocean Mapping at the Center for Coastal and Ocean Mapping, University of New Hampshire, USA. Find out more and how to apply.
Please note that the current GEBCO download application will be updated at the beginning of February 2026. We are replacing the current application with the beta release app.
Find out more about the new GEBCO data download app, featuring multi-resolution data in test regions. This application will replace the current data download app in early 2026.
