Researchers aboard the JOIDES Resolution examine a newly drilled sediment core that records the history of the West Antarctic Ice Sheet.

VIENNA—Braving a raft of icebergs, a scientific drill ship has recovered the first deep sediment cores from the Amundsen Sea, where the massive Antarctic ice sheet is rapidly melting. The 800-meter-long records, described for the first time last week at the annual meeting of the European Geosciences Union here, contain several million years of history of the West Antarctic Ice Sheet. “It’s a very strategic place to drill,” says Florence Colleoni, a paleoclimate and ice sheet modeler at the National Institute of Oceanography and Experimental Geophysics in Sgonico, Italy.
