Workshop on the Study of Arctic Change in Ocean Circulation

摘要 地址：华盛顿大学莫里森分校9712315 调查人员将举办一个讲习班，讨论今后需要进行哪些研究，以监测1994年美国和加拿大联合穿越北冰洋北冰洋的北冰洋部分观测到的海洋环流变化。 与会者将设计一个长期研究计划，提供有关1994年以前没有观察到的暖水扩散到北冰洋的程度的信息。 继续监测新的环流格局将有助于评估从太平洋主导的环流格局转变为南极主导的环流格局的原因。目前还无法确定观测到的变化是周期性的还是对全球变暖作出反应的永久性变化。 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。 如果证明具有全球变化驱动力，新的环流模式的影响将对全球环流和北冰洋冰盖的永久性产生重大影响。

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.
