中文摘要
该奖项支持了一项研究项目,该项目旨在研究跨越北冰洋大西洋水(如西斯匹次卑尔根海流)主要水流路径的五个沉积物岩心样带的沉积物积累速率。因为斯匹次卑尔根海流)。由于西斯匹次卑尔根海流是高北极地区海洋热量的主要输入源,并负责维持挪威海的海冰无冰状态,因此对该海流历史的详细了解对于完全理解从末次冰期到现在温暖的间冰期气候状态的转变至关重要。广泛的北极边缘大陆架上的热盐过程在北冰洋热盐环流中起着重要作用。该项目将研究西斯匹次卑尔根大陆架是否在末次盛冰期(大约1.8万年前)被冰川覆盖。船舶时间由挪威极地研究所免费提供。
英文摘要
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.
