Arctic-CHAMP Project Office: The Arctic Community-Wide Hydrological Analysis and Monitoring Program

北极是一个独特而重要的环境，对地球系统的动态和演变至关重要。该区域目前正在经历快速的环境变化。然而，人们对这种变化的来源和最终后果仍知之甚少。作为NSF-ARSS北极淡水综合研究(FWI)计划的一部分进行的研究不仅记录了北极水文循环的持续变化，而且记录了这些变化在全球气候动态中所起的重要作用。最近开发的关于研究需要的文件强调了北极淡水过程在生态系统、社会和全球系统中的关键作用。最近发布的搜索执行计划(搜索，2005)将淡水系统的变化描述为北极和地球系统之间最重要的联系之一。2005年11月举行的第二次北极研究规划国际会议(ICARP II)的11个工作组中，有两个几乎完全把淡水动态作为下一个十年北极研究的最高优先事项。这项提案中的工作将通过加强我们对环极地尺度上不断变化的北极系统的了解，支持搜索的目标，并为国际地球年做出贡献。本建议所述努力的主要职能是维持北极冠军科学管理办公室(SMO)，扩大SMO的支持活动组合，将FWI为实现北极冠军综合而最近确定的活动包括在内，并协助ARCS协调新出现的北极冠军科学和外联工作。智力优势：北极冠军综合和一体化问题复杂且多方面，需要一个专门的、管理良好的科学管理办公室，以提供一个有效机制，促进项目参与者和其他相关研究活动之间的最大限度合作和协调。第一次世界大战参与者的研究和综合活动现在已经确立，并正在朝着通过泛北极淡水循环最终实现对大气/陆地/海洋联系的广泛理解的宝贵综合；然而，正如我们已经发现的那样，综合活动的协调对于实现最大生产力和全系统范围的综合至关重要。SMO将具体：支持北极CHAMP科学指导委员会正在进行的活动在FWI项目中催化合成，并使FWI合成与ARCS社区范围的合成相关组织北极CHAMP和FWI科学会议和研讨会支持及时交付与CHAMP相关的科学数据产品，并开发协调的FWI合成数据产品ADCC前存档2007年(针对FWI调查人员)和2008年(作为IPY附属会议)组织和举办两个大型FWI合成讲习班，包括行使FWI合成概要与其他美国和国际机构合作伙伴的联络活动，特别侧重于IPY和ICARP-II，向科学家和更广泛的用户群体宣传北极冠军的努力结果。

The Arctic constitutes a unique and important environment, central to the dynamics and evolution of the Earth system. The region is currently experiencing rapid environmental change. The sources and ultimate consequences of such change are, however, still poorly understood. Research conducted as part of the NSF-ARCSS Arctic Freshwater Integration Study (FWI) program has documented not only the ongoing changes in the arctic hydrological cycle, but also the important role these changes play in global climate dynamics. Recently developed documents on research needs have emphasized the critical function of arctic freshwater processes in ecosystem, social and global systems. The recently released SEARCH Implementation Plan (SEARCH, 2005) describes changes in the freshwater system as one of the most consequential links between the arctic and the earth systems. Two of eleven working groups in the November 2005 International Conference on Arctic Research Planning II (ICARP II) focused almost exclusively on freshwater dynamics as the highest priority for the next decade of arctic research. The work in this proposal will support the goals of SEARCH and contribute to IPY through enhancing our understanding of the changing arctic system on circumpolar scales. The primary function of the efforts described in this proposal is to maintain the Arctic- CHAMP Science Management Office (SMO), expand the SMO portfolio of support activities to include those recently identified by the FWI rank-and-file to realize the FWI Synthesis, and to assist ARCSS in coordinating emerging Arctic-CHAMP science and outreach efforts.Intellectual Merit: The Arctic-CHAMP synthesis and integration issues are complex and multi-faceted and a dedicated, well-managed, Science Management Office is necessary to provide an efficient mechanism for facilitating maximum collaboration and coordination among project participants and other related research activities. The research and integration activities of the FWI participants is now well established and progressing towards ultimately achieving a valuable synthesis of broad-scale understanding of atmospheric/terrestrial/oceanic connections through the freshwater cycle of the pan- Arctic; however, and as we have found, coordination of synthesis activities is essential to achieve maximum productivity and full-system scale integration. The SMO will specifically:Support the ongoing activities of the Arctic-CHAMP Scientific Steering CommitteeCatalyze synthesis across FWI projects and make FWI synthesis relevant to ARCSS community wide synthesisOrganize Arctic-CHAMP and FWI scientific meetings and symposiaSupport the timely delivery of CHAMP-related science data products and develop a coordinatedpre-ADCC archive of FWI synthesis data productsOrganize and conduct two major FWI synthesis Workshops in 2007 (for FWI investigators) and 2008 (as an IPY-affiliated meeting), including the exercise of the FWI synthesis compendiumConduct liaison activities with other US and international agency partners, with a special focus on IPY and ICARP-II.Disseminate findings of Arctic-CHAMP effort, to scientists and broader user communities.
