Surface lake on Greenland Ice Sheet (IMAGE)
Caption
Lakes form on the surface of the Greenland ice sheet each summer as the weather warms. They exist for weeks or months but can drain in a matter of hours due to hydrofracturing, transferring millions of cubic metres of water and heat to the base of the ice sheet. Now, Cambridge researchers have used satellites to 'see in the dark' and show that these lakes can also drain in the winter.
