项目摘要

Collaborative Research on Carbon, Water, and Energy Balance of the Arctic Landscapeat Flagship Observatories in Alaska and SiberiaABSTRACTThe arctic landscape interacts with the global and regional climate by exchanging carbon dioxide, methane, water, and energy with the atmosphere. Understanding how these exchanges are regulated and how they change is a key goal of the US Study of Environmental Arctic Change and the NSF Arctic Observatory Network. The first goal of this work is year round monitoring of carbon, water, and energy balance at two arctic sites, Imnavait Creek in Alaska and Cherskii in Siberia. The work will be a collaboration among researchers from the Marine Biological Laboratory, the University of Alaska Fairbanks, Northeast Science Station, Russia, and the University of Michigan. The second goal is the development of these two sites as ?Flagship? observatories for research on arctic lands and freshwaters. The main task here is to integrate the new carbon, water, and energy balance data with the already large, diverse, and growing data bases from other research done at these sites. A third aim is to promote PanArctic comparisons and development of PanArctic data bases. Broader impacts include contributions to education, including underrepresented groups, through participation in the Logan Science Journalism program, the Arctic Long-Term Ecological Research Schoolyard program, and outreach to Native Alaskan communities. Research and education infrastructure will be enhanced by making the data bases available online. Benefits to society include improved understanding of the impacts of climate change, especially in Alaska where the local residents are closely tied to the land through traditional, subsistence lifestyles.

阿拉斯加和西伯利亚旗舰天文台对北极景观碳、水和能量平衡的合作研究摘要北极景观通过与大气交换二氧化碳、甲烷、水和能量来与全球和区域气候相互作用。了解这些交换如何受到监管以及它们如何变化是美国北极环境变化研究和美国国家科学基金会北极观测站网络的一个关键目标。这项工作的第一个目标是全年监测两个北极地点（阿拉斯加的伊姆纳瓦伊特溪和西伯利亚的切尔斯基）的碳、水和能量平衡。这项工作将由海洋生物实验室、阿拉斯加大学费尔班克斯分校、俄罗斯东北科学站和密歇根大学的研究人员合作完成。第二个目标是将这两个网站发展为“旗舰”网站。研究北极陆地和淡水的观测站。这里的主要任务是将新的碳、水和能量平衡数据与在这些地点进行的其他研究中已经庞大、多样化且不断增长的数据库整合起来。第三个目标是促进泛北极比较和泛北极数据库的开发。更广泛的影响包括通过参与洛根科学新闻计划、北极长期生态研究校园计划以及对阿拉斯加原住民社区的推广，对教育做出贡献，包括对代表性不足的群体的贡献。通过在线提供数据库，研究和教育基础设施将得到加强。对社会的好处包括提高对气候变化影响的了解，特别是在阿拉斯加，当地居民通过传统的生存生活方式与土地紧密相连。
