# NASA - The Bedrock Beneath usDzh7l5HZw

Our understanding of what lies beneath the world's biggest ice sheet has taken another leap forward. In this video we strip 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.
