Coordination and Participation: US-UK Joint Workshop on Arctic Research

该提案是为参加2012年在英国剑桥大学克莱尔学院举行的美国-英国北极研究联合研讨会的大约25名美国与会者提供差旅支助。该研讨会将建立在英国自然环境研究理事会（NERC）通过其北极研究计划对北极研究进行的重大新投资的基础上。研讨会将使美国调查人员能够讨论共同感兴趣的领域，潜在的合作以及与英国同事共享后勤资源的机会。参与者将由一个委员会根据他们对该主题的预期贡献以及他们在相关研究主题、学科平衡和地理位置方面的经验进行选择。预计美国参与者将熟悉北极环境变化研究计划的目标。美国正在为未来五年制定一套最新的科学目标，目前包括：提高对海冰变化及其对生态系统、人类活动和气候影响的理解和预测;了解浅层永久冻土层丧失对北极和全球系统的影响;提高对未来陆地的预测。冰损失和对海平面的影响;分析北极环境变化的社会和政策影响。NERC正在开发一个专注于四个相关科学目标的项目，详细信息见其科学计划（http：//www.nerc.ac.uk/research/programmes/arctic/documents/arctic-science-plan.pdf）：了解北极目前的快速变化并确定其原因;量化导致北极甲烷和二氧化碳释放的过程;减少北极气候和相关区域地球化学预测的不确定性;以及评估与北极气候快速变化相关的潜艇危险的可能风险。这一提议将促进国际合作，推动两项研究北极变化的国家倡议。

This proposal is for travel support to approximately 25 U.S. participants to the US-UK Joint Workshop on Arctic Research to be held at Clare College, University of Cambridge, UK in 2012. The workshop will build on significant new investments in arctic research made by the UK Natural Environment Research Council (NERC) through its Arctic Research Programme. The workshop will enable U.S. investigators to discuss common areas of interest, potential collaborations, and opportunities for sharing logistical resources with their UK colleagues. Participants will be selected by a committee based upon their expected contributions to the subject and their experience in relevant research themes, disciplinary balance and geographical location. U.S. participants are anticipated to be familiar with the goals of the Study of Environmental Arctic Change SEARCH. SEARCH is in the process of developing an updated set of scientific goals for the next five years, which currently include: improving understanding and prediction of sea ice changes and the consequences for ecosystems, human activities, and climate; understanding the consequences of the loss of shallow permafrost on arctic and global systems; improving predictions of future land?]ice loss and impacts on sea level; and analyzing societal and policy implications of arctic environmental change. NERC is developing a program focused on four linked scientific objectives, detailed in its science plan (http://www.nerc.ac.uk/research/programmes/arctic/documents/arctic-science-plan.pdf): understanding and attributing the current rapid changes in the Arctic; quantifying processes leading to Arctic methane and carbon dioxide release; reducing uncertainty in Arctic climate and associated regional biogeochemistry predictions; and assessing the likely risks of submarine hazards associated with rapid Arctic climate change. This proposal will facilitate international collaboration and furtherance of the two national initiatives to study change in the Arctic.
