This award supports a program of research to study sediment accumulation rates in five transects of sediment cores that cross today's primary flow path of Arctic bound Atlantic water (e.g., the West Spitsbergen Current). Because the Wets Spitsbergen Current). Because the West Spitsbergen Current is the primary importer of ocean heat to the High Arctic, and is responsible for maintaining the sea-ice free conditions in the Norwegian Sea, detailed knowledge of the history of this current is critical to a complete understanding of the transition form the last glaciation to the present warm, interglacial climate state. Thermohaline processes on the broad Arctic margin shelves play an important role in the thermohaline circulation of the Arctic Seas. This project will examine whether the West Spitsbergen Continental Shelf was glaciated during the Last Glacial Maximum (approximately 18 thousand years ago). Ship time is provided at no charge to this proposal by the Norwegian Polar Research Institute.

该奖项支持了一项研究计划，该计划旨在研究横跨当今北极大西洋水域(例如西斯皮茨卑尔根海流)的主要流动路径的五个沉积物岩芯的沉积物累积速率。因为韦茨·斯皮茨卑尔根流)。由于西斯皮茨卑尔根洋流是北极高地海洋热量的主要输入者，并负责维持挪威海的无海冰条件，因此，详细了解这一洋流的历史对于全面了解从最后一次冰川到目前温暖的间冰期气候状态的过渡至关重要。宽阔的北极边缘大陆架上的温盐过程在北冰洋的温盐环流中发挥着重要作用。该项目将研究西斯皮茨卑尔根大陆架是否在最后一次冰川盛期(约18,000年前)期间冰化。挪威极地研究所对此提议免费提供船期。
