36. THE PALEOCEANOGRAPHIC HISTORY OF THE NORTH ATLANTIC-ARCTIC GATEWAYS: SYNTHESIS OF THE LEG 151 DRILLING RESULTS1
During Leg 151, seven locations were drilled in the western Norwegian-Greenland Sea, in Fram Strait, and on the Yermak Plateau. These sites allow us to address the paleoceanographic and climatic history of the surface- and bottom-water masses in high Northern Hemisphere deep-sea basins, of the mode...
