Our understanding of what lies beneath the world's biggest ice sheet has taken another leap forward. Thanks to work led by the British Antarctic Survey, scientists have a new 3D map of Antarctica’s ice and bedrock. The map, called Bedmap2, incorporates millions of new measurements, including data collected by NASA's ICESat satellite and airborne Operation IceBridge mission. The result is a virtual reconstruction of the continent’s bedrock topography and ice layers captured in never-before-seen detail. Antarctica plays a large role in the global climate system. The melting and emptying of its ice into the sea influences ocean currents and the rate of sea level rise. By having a precise map of Antarctica’s mountains, ridges, slopes and valleys—all of which affect how fast the continent's ice travels across the ice sheet—scientists can better predict future rates of ice flow. Watch the video to learn more.
