Spatial and Temporal Variability of Arctic Mixed Layer from Russian and American Data

华盛顿詹姆斯大学OPP-9712315莫里森研究人员将举办一次研讨会，讨论监测1994年北冰洋美国和加拿大联合横穿北冰洋的洋流变化所需的未来研究需要。与会者将设计一项长期研究计划，提供1994年前没有观测到的暖水扩散到北冰洋的范围的信息。继续监测新的环流模式将使人们能够评估从太平洋主导的环流模式转变为大西洋主导模式的原因。目前还不可能确定观测到的变化是周期性的，还是应对全球变暖的永久性变化。作为研讨会成果而设计的研究方案将提供评估全球变化对北冰洋可能产生的影响所需的长期数据集。如果被证明具有全球变化的驱动力，新的环流模式的影响将对全球环流和北冰洋冰盖的持久性产生重大影响。

ABSTRACT OPP-9712315 MORISON, JAMES UNIVERSITY OF WASHINGTON The investigators will conduct a workshop on the future research needs required to monitor a change in oceanic circulation observed on the 1994 Arctic Ocean Section joint US and Canadian traverse of the Arctic Ocean. The participants will design a long-term research program that will provide information about the extent of warm water spreading into the Arctic Ocean that had not been observed prior to 1994. The continued monitoring of the new circulation pattern will allow assessment of the causes for the shift to an Atlantic-dominated pattern from a Pacific-dominated circulation pattern. At present it is impossible to determine if the observed change is cyclic or a permanent change in response to global warming. The research program designed as a result of the workshop will provide the long-term dataset necessary to assess the possible global change impact on the Arctic Ocean. If shown to have a global change driving force, the impacts of the new circulation pattern will have major implications for global circulation and the permanence of the Arctic Ocean ice pack.
