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.

为一个国际性的、跨学科的讲习班提供了资金，讲习班的题目是：北冰洋东部上层海洋和海冰相互作用的观测？。 该研讨会建立在为拟议的“欧亚盆地冰营”（EBIC）实地计划制定科学想法的重要努力的基础上，并将促进国际支持。EBIC将收集数据来解决以下问题：1。是什么过程，以及它们的大小，解释了大西洋水在沿着北极东部边缘循环时海洋热含量的迅速减少？2.这些过程如何与浮冰和大气相互作用，以改变气候变化中北极海冰的演变？和3.上层海洋的特性如何影响北冰洋研究不足区域的营养物和浮游动物组合的基本过程？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。 该研讨会将为上述实地项目的范围制定一项具体的科学计划，并得到美国和国际北极社区的广泛贡献。根据这一总目标，拟议的讲习班？的目标是：1。确定关键的科学问题和假设，必须解决的实验计划，以显着推进我们的理解海冰和上层海洋的过程和相互作用在北冰洋东部，2。确定解决这些问题和假设的基本技术和平台，包括但不限于船舶调查的潜力;一个或多个集中的冰营地;漂流者，水下和空中自动驾驶车辆;以及卫星或空中遥感。制定实验后勤计划;确定时间表、多机构供资来源、国际合作战略和管理办法;制定在更广泛的北极科学界内协调拟议活动的方法，确定卫星和建模界在冰营期间收集观测数据方面的需求，并制定青年科学家参与项目活动的计划。该文件将在所有研讨会参与者中分发，以征求进一步的意见，然后张贴，广泛宣传并直接与社区分享，以征求进一步的意见，然后在研讨会后三个月定稿。大量的热量通过源自大西洋的沃茨输送到北冰洋。 关于这种热量的命运，特别是它在融化海冰方面的重要性，有很多猜测。 最近海冰的减少和夏季开阔水域的大面积扩张可能改变了北冰洋欧亚海盆的过程环境。 拟议的讲习班将汇集国际科学家讨论这些问题，并计划可能的实地工作，研究这种热量在不断变化的环境中的命运。 从这一研究中得出的认识对于预测欧亚海盆以及可能更远的加拿大海盆的海冰覆盖情况将是重要的。
