photo montage of science activities at Greenland's Summit Camp

Science activities and daily life for Matthew Shupe and other scientists at Summit Camp in Greenland: launching a weather balloon (left), fog leaves a coating of feather-like ice crystals on exposed surfaces; the ily work in the Mobile Science Facility, built on skis so that it can be moved to prevent snow burial; ‘Arctic Ovens,’ the tents named for their ability to keep occupants warm in subzero temperatures.
