The Bedrock Beneath Antarctica

Our understanding of what lies beneath the world's biggest ice sheet
has taken another leap forward. This video strips away Antarctic ice to
reveal a new, and much more detailed map of the bedrock below. This
map, called Bedmap2, was compiled by the British Antarctic Survey and
incorporates millions of new measurements, including substantial data
sets from NASA's ICESat satellite and an airborne mission called
Operation IceBridge.
