Scientists walk along the edge of a large canyon carved by meltwater stream flow across the surface of the Greenland ice sheet. The lines along the canyon wall show the stratigraphic layers of ice and snow laid down over the decades. WHOI glaciologist Sarah Das, geophysicist Mark Behn, and other colleagues from WHOI and the University of Washington will travel to Greenland this summer for the third year of an ongoing study of how Greenland's ice is melting and moving.

WHOI glaciologist Sarah Das, geophysicist Mark Behn, and other colleagues from WHOI and the University of Washington will continue their studies of how Greenland's ice is melting
and moving in the summer of 2008.
Caption from Oceanus magazine, Vol. 46, No. 3, back cover:
A GRAND ICE CANYON—Scientists Mark Behn (Woods Hole Oceanographic Institution) and Ian Joughin (University of Washington) peer down the cliff of a deep channel cut through the Greenland Ice Sheet by a river of water—much the way the Colorado River created the Grand Canyon. Rivers form atop the ice sheet as the summer sun melts ice. On expeditions to Greenland over the past three years, Behn, Joughin, and WHOI glaciologist Sarah Das have investigated whether lakes and rivers that form atop the ice in summer speed up the flow of glaciers toward the sea, especially in a warming world. See story on Page 4.
