Scientists from Woods Hole Oceanographic Institute and the University of Washington have for the first time documented the sudden and complete drainage of meltwater from the surface of the Greenland icecap, and found that it can crack the cap all the way to the bottom. The consequent lubricating effect can increase the horizontal flow 50 to 100 percent.
