Coordination and Participation: Workshop "Observations of upper-ocean and sea-ice interactions in the Eastern Arctic Ocean"

为题为“观察北冰洋东部的上层海洋和海冰相互作用”的国际跨学科讲习班提供了资金。该研讨会建立在先前为拟议的“欧亚盆地冰营”(EBIC)实地计划制定科学想法方面的重大努力的基础上，并将促进国际支持。EBIC将收集用于解决以下问题的数据：1.解释沿北极东部边缘循环的大西洋水的海洋热含量迅速下降的过程及其程度是什么？2.这些过程如何与积冰和大气相互作用，以改变气候变化中北极海冰的演变？3.上层海洋的性质如何影响北冰洋这一研究较差地区的营养物质和浮游动物群落的基本过程？研讨会将使美国和国际调查人员能够讨论共同感兴趣的领域、潜在的合作以及共享后勤资源的机会。该研讨会将在美国和国际北极社区的广泛贡献下，为上述实地计划的范围制定一项具体的科学计划。根据这一总体目标，拟议的研讨会？S的目标是：1.确定必须由实验计划解决的关键科学问题和假设，以便显著推进我们对北冰洋东部海冰和上层海洋过程和相互作用的了解；2.确定解决这些问题和假设的关键技术和平台，包括但不限于船舶勘测的可能性；一个或多个重点冰营；漂流者、水下和空中自主飞行器；以及卫星或航空遥感；3.制定实验后勤计划；4.确定时间表、多机构资金来源、国际合作战略和管理方法，以及5。制定在更广泛的北极科学界内协调拟议活动的方法，根据冰营期间收集的观测数据确定卫星和模型界的需求，并制定让青年科学家参与项目活动的计划。讲习班协调员将编写一份总结讲习班成果的白皮书草案。这份文件将在所有研讨会参与者中传阅以征求进一步意见，然后张贴、广泛宣传并直接与社区分享以征求进一步意见，然后在研讨会三个月后最终定稿。大量热量被输送到北冰洋，其中的水起源于大西洋。关于这种高温的命运有很多猜测，特别是它在海冰融化中的重要性。最近海冰的减少和夏季大片开放水域可能改变了北冰洋欧亚盆地的过程环境。拟议的研讨会将使国际科学家齐聚一堂，讨论这些问题，并规划一项可能的实地工作，以研究这种高温在不断变化的环境中的命运。这项研究的结果将对预测欧亚盆地和加拿大盆地以外的海冰覆盖情况具有重要意义。

Funds are provided for an international, interdisciplinary Workshop entitled ?Observations of upper-ocean and sea-ice interactions in the Eastern Arctic Ocean?. The workshop builds on significant previous efforts in developing scientific ideas for the proposed "Eurasian Basin Ice Camp" (EBIC) field program and will promote international support. EBIC would collect data with which to address the questions: 1. What are the processes, and their magnitudes, that explain the rapid reduction in ocean heat content of the Atlantic Water as it circulates along the margins of the eastern Arctic?2. How do these processes interact with the pack ice and atmosphere to modify the evolution of Arctic sea ice in a changing climate? and 3. How do properties of the upper ocean affect fundamental processes of nutrients and zooplankton assemblages in the poorly studies region of the Arctic Ocean? The workshop will enable US and international investigators to discuss common areas of interest, potential collaborations, and opportunities for sharing logistical resources. This workshop will develop a concrete science plan, with broad US and international Arctic community contribution, for the scope of the abovementioned field program. Following this general goal, the proposed Workshop?s objectives are to:1. identify key science questions and hypotheses that must be addressed by an experimental program in order to significantly advance our understanding of sea-ice and upper-ocean processes and interactions in the eastern Arctic Ocean,2. identify essential technologies and platforms to address these questions and hypotheses, including, but not limited to, the potential for ship surveys; one or more focused ice camps; drifters, underwater and airborne autonomous vehicles; and satellite or airborne remote sensing,3. develop plans for experiment logistics, 4. identify timelines, multi-agency funding sources, international cooperation strategies, and management approaches, and5. develop approaches for coordination of the proposed activities within the wider Arctic science community, identify needs of the satellite and modeling communities in terms of observational data to be collected during the ice camp, and develop plans for engagement of young scientists in project activities.The workshop coordinators will develop a draft White Paper summarizing the workshop outcomes. This document will be circulated amongst all workshop participants for further comment, then posted, broadly advertised and shared directly with the community for further comment before being finalized three months after the workshop.Large amounts of heat are transported into the Arctic Ocean with waters originating in the Atlantic Ocean. There has been much speculation concerning the fate of this heat, particularly its importance in melting sea ice. Recent reductions in sea ice and large expanses of summer open water may have changed the process environment of the Eurasian Basin of the Arctic Ocean. The proposed workshop would bring together international scientists to discuss these issues and to plan a possible field effort to study the fate of this heat in a changing environment. The resultant understanding from such a study would be important for forecasting sea ice cover over the Eurasian Basin and, possibly, beyond, to the Canadian Basin.
