Paleoglaciology’s grand unsolved problem
Abstract The paleoglaciological concept that during the Pleistocene glacial hemi-cycles a super-large, structurally complex ice sheet developed in the Arctic and behaved as a single dynamic system. as the Antarctic ice sheet does today, has not yet been subjected to concerted studies designed to tes...
