CryoSat maps largest-ever flood beneath Antarctica

ESA’s CryoSat satellite has found a vast crater in Antarctica’s icy surface. Scientists believe it was left behind when a lake lying under about 3 km of ice suddenly drained. By combining new measurements acquired by CryoSat with older data from NASA’s ICESat satellite, the team has mapped the large crater left behind by a lake, and even determined the scale of the flood that formed it.
