Description

Profile through the Antarctic ice sheet (A) Bellingshausen Sea - West Antarctic ice sheet - Ross ice shelf - Ross Sea (B). The profile shows that most of the West Antarctic ice sheet is grounded below sea level which makes it sensitive to sea level rise. If the contact of the ice to the bottom rocks is lost seaward of the grounding line, the ice sheet becomes significantly thinner (some 100 m), forming a shelf ice.

  • lines in profile are lines of similar age; annual layers in the center are thinning from top to bottom
  • turquoise areas: ice shelf
  • red areas: not ice covered (2.8 % of total area)
  • blue shaded areas increment by 1000 m in thickness
