We have been working to update our GEBCO data download application and a beta test version is now available at https://betadownload.gebco.net
The new application allows users to select defined regions to download data, and explore multi-resolution data in selected regions in the waters surrounding Australia, New Zealand, and the Hawaiian islands.
Data are available in NetCDF, GeoTIFF, and ASCII formats. The new download application will replace the current data download application in early 2026. To download global coverage grids, please follow https://www.gebco.net/data-products/gridded-bathymetry-data
To provide feedback on the new download app, please contact gdacc@seabed2030.org
