Antarctica topography and bathymetry
Subglacial topography and bathymetry of Antarctica.
As indicated at the left of the map, the different shades of blue and purple
indicates the parts of the ocean bottom and the bedrock under the ice,
that are below sea level.
The other colors indicate the Antarctic bedrock that extends over the sea level.
Each color represents a range of 2,500 feet.
The map is not corrected for rising sea levels and isostatic rebound,
that would occur if the Antarctic ice sheet completely melted to expose the bedrock surface. Map March 13, 2008
