Antarctica topography

The ice surface- and bed topography of Antarctica.

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.

Polar surface topography

Polar maps of the Earth’s surface topography showing the bedrock elevation across oceans, land, and ice sheets.

Polar maps of the Earth’s surface topography showing the bedrock elevation across oceans, land, and ice sheets of either the Northern (Arctic) or the Southern (Antarctic) hemisphere. Shown is ETOPO1 (Amante and Eakins 2009), a 1 arc-minute global relief model of Earth’s surface that integrates land topography and ocean bathymetry. The Scientific colour map ‘bukavu‘ is used to represent data accurately and to all readers.
