Mapa + Description: The above map shows the subglacial topography and bathymetry of Antarctica. As indicated by the scale on left-hand side, the different shades of blue and purple indicate parts of the ocean floor and sub-ice bedrock, which are below sea level. The other colours indicate Antarctic bedrock lying above sea level. Each colour represents an interval of 2,500 feet in elevation. Map is not corrected for sea level rise or isostatic rebound, which would occur if the Antarctic ice sheet completely melted to expose the bedrock surface.

  • Date: 13 March 2008
  • Source: This map was prepared from BEDMAP gridded data-set for bed-elevation south of 60 degrees S using Global Mapper 7.0.1. The faint rectilinear pattern seen in the shaded relief is an artifact of the gridding of data from linear seismic surveys.
