Attached by rope to a waiting helicopter, researcher Carl Gladish walks back after deploying a GPS seismometer, or GeoPebble, to track glacial movement on Jakobshavn Glacier, near Ilulissat, Greenland. Chief researcher David Holland, hopes to eventually deploy scores of the devices to measure ice loss in Greenland.

Atop roughly two miles of ice, a small laboratory structure bristles with sensors at Summit Station, a remote research center operated by the U.S. National Science Foundation (NSF), and situated 10,500 feet above sea level, on top of the Greenland ice sheet. Across Greenland's white landscape, small teams of researchers from around the world are searching for clues to the potential effects of global warming on Greenland's ice.
