Greenpeace crew members help scientists to take depth soundings from the bottom of 'melt-lakes' which are 4.5 Miles South of Swiss Camp, inland from Disko Bay and situated in West Greenland. Two lakes were sounded, 2.5miles apart, the coordinates for these were: Lake 1 - 69º32m N 49º07m W and Lake 2 - 69º29m N 49º12m W. Greenpeace and an independent NASA-funded scientist completed measurements of the melt lakes on the Greenland Ice Sheet that show its vulnerability to warming temperatures. The measurements are the last scheduled activity as the Greenpeace ship Arctic Sunrise wraps up its two-month expedition to document the impacts of climate change on Greenland's ice sheet and glaciers.
