Benny Hopson from the Barrow (Alaska) Arctic Science Consortium drills a core sample from sea ice in the Chukchi Sea on July 4, 2010. The core is sliced up into puck-sized sections and stored onboard the U.S. Coast Guard Healy for analysis in the ship's lab. Impacts of Climate change on the Eco-Systems and Chemistry of the Arctic Pacific Environment (ICESCAPE) is a multi-year NASA shipborne project. The bulk of the research will take place in the Beaufort and Chukchi Sea’s in summer of 2010 and fall of 2011. Photo Credit: (NASA/Kathryn Hansen)
