Expedition to drill through glacier

Aug. 3, 2015--University of Delaware researchers are part of an international research team that plans to drill through a floating Greenland glacier to capture the first-ever measurements of the ocean conditions underneath.

Petermann Glacier is one of the two largest remaining glaciers in Greenland that terminate in floating shelves. The glacier connects the great Greenland ice sheet directly with the ocean.

As part of the U.S.-Swedish expedition, UD oceanographer Andreas Muenchow and doctoral student Peter Washam are collaborating with researchers from Oregon State University and the University of Gothenburg to document changes in the grounded Petermann Glacier, its buttressing ice shelf and ocean conditions since the end of the last glacial period.

Washam is part of the ice-drilling team led by the British Antarctic Survey that will drill through 200-500 meters of glacier ice, a distance equivalent to one to two Empire State Buildings.
