The ice surface- and bed topography of Antarctica with elevations relative to present-day global mean sea-level. Almost 98% of the Antarctic continent surface is covered by ice and its weight is pushing down the rocky crust below it. If the continental ice sheet would melt, isostatic post-glacial rebound would cause an uplift of the rocky surface of Antarctica. Elevations are taken from the BedMachine compilations (Morlighem et al., 2020) and the Scientific colour map ‚oleron‘ is used to represent bed topography accurately and to all readers.
