The above map shows the subglacial topography of Antarctica. As indicated by the scale on left-hand side, blue represents portions of Antarctica lying below sea level. The other colors indicate Antarctic bedrock lying above sea level. Each color 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.
