Glaciologist Dr Jason Box adjusts his remote time-lapse cameras which are trained across Petermann Glacier, one of Greenland's largest and most northerly glaciers. One of the cracks in the glacier is visible in the frame. The images from the two cameras, will be stitched together to make a panoramic image. The cliffs at 980 metres high (3,000 feet) provide an ideal vantage point to monitor the glacier. The installation of the time lapse cameras is a joint initiative between Greenpeace and Extreme Ice Survey (EIS). It is hoped that the remote cameras will give a clear picture of the process by which the glacier breaks and how parts of it drift out to sea. A team of scientists assisted by experts in ice logistics, intend to document the glacier's ongoing disintegration. Recent satellite images show that an expanse larger than New York's Manhattan island is ready to break off from Petermann Glacier.
