To investigate the mechanisms involved in driving changes in the Antarctic ice sheet the researchers looked at a wide range of geological records, from cores of sediment from the ocean bottom near Antarctica to records of land exposure and past shorelines. This image was taken in 2007 onboard research vessel Marion Dufresne II in the Scotia Sea during the coring campaign.
