Details

These data providers don't publish the data in cloud-ready form, so we have a few versions convert to Cloud-Optimized GeoTIFF, always using the 'ice surface elevation' form. See R package sds which records the latest available source in sds::gebco() and has some time-stamped versions of that function for older copies.

The process for creating a COG is recorded here: derived GEBCO reformat.
