Alan Hubbard, a glaciologist from University Of Wales, Aberystwyth, holds self-powered GPS units on the deck of Greenpeace ship MY Arctic Sunrise at the Petermann glacier at 81 degrees north in Greenland. The self powered units transfer data to a base station that will tell the scientists the speed at which different parts of the glacier move as parts break off. Greenpeace and leading climate scientists are in Greenland for a 3 month expedition using their icebreaking ship the Arctic Sunrise to gather climate change data for the Copenhagen climate summit in December 2009.
