Greenland, Sermilik Fjord, August 2009 - Night time sees calm waters amongst the bergs of Sermilik Fjord on south east Greenland. Helheim glacier on south east Greenland is the focus for Leg 2 of Greenpeace's Arctic Impacts Tour. The icebreaking ship, The Arctic Sunrise and her crew, are facilitating the field work of oceanographers from Woods Hole Oceanographic Institute, in order calculate the impact of ocean warming on east Greenland's outlet glaciers. The scientists are keen to ascertain whether subglacial melting may be driven by contact with subtropical water -a field where little research exists. They are collecting data from the 'ice ocean interface' in Sermilik Fjord (at Helheim glacier) and Kangerdlugssuaq Fjord (at Kangerdlugssuaq glacier). These two glaciers, found by glaciologists to be rapidly accelerating, are central in the rapid and unpredicted (ice) 'mass loss' that Greenland has been experiencing in recent years. It is widely held that the contribution to sea level rise by Greenland's outlet glaciers, has been underestimated in recent predictions on climate change. Greenpeace intends to take a message to the Copenhagen summit on climate change, held this December, from its 3-month long Arctic Impacts Tour around Greenland. Photo by Nick Cobbing / Greenpeace
