Pre-LGM open-water conditions south of the Drygalski Ice Tongue, Ross Sea, Antarctica
AbstractA marine sediment core collected from the Nordenskjold Basin, to the south of the Drygalski Ice Tongue, provides new sedimentological and chronological data for reconstructing the Pleistocene glacial history and palaeoenvironmental evolution of Victoria Land. The core consists of an over con...
