Sediment from subglacial Lake Whillans, including mud, clay and rocks, makes its first supraglacial appearance on the multicorer instrument retrieved from the borehole. Reed Scherer (right) speeds the tray of sediment to the lab as Alex Michaud (center) and Ross Powell stabilize the multicorer above the borehole. The multicorer was successfully deployed to the bottom of Lake Whillans three times on January 30, providing abundant samples for chemical, physical and biological analysis.
