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迅速的环境变化。然而，人们对这种变化的来源和最终后果仍然知之甚少。作为NSF-ARCSS北极淡水整合研究（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，而且还记录了这些变化在全球气候动态中的重要作用。最近编写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。最近公布的《北极执行计划》（2005年）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。在2005年11月举行的第二届国际北极研究规划会议（IARP II）上，11个工作组中的两个几乎完全专注于淡水动态，将其作为下一个十年北极研究的最高优先事项。本提案中的工作将支持北极年的目标，并通过加强我们对北极圈尺度上不断变化的北极系统的理解，为国际极地年做出贡献。本提案中所述工作的主要职能是维持北极- CHAMP科学管理办公室（SMO），扩大SMO的支助活动组合，以包括FWI普通成员最近确定的那些活动，以实现FWI综合，并协助ARCSS协调新出现的北极-CHAMP科学和外联工作。北极-CHAMP的综合和一体化问题是复杂和多方面的，需要一个专门的、管理良好的科学管理办公室，以提供一个有效的机制，促进项目参与者和其他相关研究活动之间的最大限度的合作和协调。FWI参与者的研究和整合活动现已确立，并朝着最终实现对通过泛北极淡水循环的大气/陆地/海洋联系的广泛理解的有价值的综合的方向取得进展;然而，正如我们所发现的，综合活动的协调对于实现最大生产力和全系统规模的整合至关重要。测绘处具体将：支持北极-CHAMP科学指导委员会正在进行的活动促进FWI项目的综合，使FWI综合与ARCSS社区综合相关组织北极-CHAMP和FWI科学会议和专题讨论会支持及时提供与CHAMP有关的科学数据产品，并开发FWI综合数据产品的协调前ADCC档案2007年组织和举办两次重要的FWI综合研讨会（供FWI调查员使用）和2008年（作为国际和平年附属会议），包括执行《森林工作倡议综合纲要》与其他美国和国际机构伙伴开展联络活动，向科学家和更广泛的用户社区传播北极-CHAMP努力的结果。

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.
