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.

关于阿拉斯加北极景观旗舰观测站的碳，水和能源平衡的合作研究，北极景观通过交换二氧化碳，甲烷，水和能量与氛围与全球和地区气候相互作用。 了解这些交流的调节方式以及它们如何变化是美国对环境北极变化和NSF北极观测网络的关键目标。 这项工作的第一个目标是全年对两个北极场所的碳，水和能量平衡的监测，阿拉斯加的Imnavait Creek和西伯利亚的Cherskii。 这项工作将是来自海洋生物实验室，阿拉斯加费尔班克斯大学，东北科学站，俄罗斯和密歇根大学的研究人员的合作。 第二个目标是将这两个站点作为旗舰产品的发展？关于北极土地和淡水研究的观察者。 这里的主要任务是将新的碳，水和能源平衡数据与已在这些站点进行的其他研究中已经大量，多样化且不断增长的数据基础整合在一起。 第三个目的是促进阵发比较和开发阵发数据库。 通过参加洛根科学新闻计划，北极长期的生态研究校园计划以及向阿拉斯加土著人社区的宣传，更广泛的影响包括对教育的贡献，包括代表性不足的群体。 通过在线提供数据库，将增强研究和教育基础架构。 对社会的好处包括对气候变化的影响的了解，尤其是在阿拉斯加，当地居民通过传统的自给自足的生活方式与土地紧密相关。
