The cause is thought to be a deeply buried lake that suddenly over-topped. Satellites were used to map the crater that developed as the 2.7 km-thick overlying ice sheet slumped to fill the void left by the escaping water. The peak discharge would have been more than double the normal flow rate of London’s River Thames, researchers say. The location of the flood was Cook Sub-Glacial Lake (SGL) in the east of the continent, and the event itself occurred over a period of about 18 months in 2007-2008. It was detected and described using a combination of data gathered by the now-retired US Icesat mission and Europe’s new Cryosat platform. The American spacecraft’s laser altimeter first noted a drop in the…
