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.

北极景观碳、水和能量平衡的合作研究阿拉斯加和西伯利亚的旗舰观测站摘要北极景观通过与大气交换二氧化碳、甲烷、水和能量，与全球和区域气候相互作用。了解这些交换是如何受到监管的，以及它们是如何变化的，这是美国北极环境变化研究和NSF北极观测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的碳、水和能源平衡，这两个地点是阿拉斯加的因纳瓦伊特克里克和西伯利亚的切尔斯基市。这项工作将由来自海洋生物实验室、阿拉斯加大学费尔班克斯大学、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天文台。这里的主要任务是将新的碳、水和能源平衡数据与这些地点进行的其他研究的已经庞大、多样化和不断增长的数据库相结合。第三个目标是促进对全北极数据库的比较和开发。更广泛的影响包括通过参与洛根科学新闻计划、北极长期生态研究学校计划以及接触阿拉斯加原住民社区，对教育做出贡献，包括代表性不足的群体。通过在网上提供数据库，研究和教育基础设施将得到加强。对社会的好处包括更好地了解气候变化的影响，特别是在阿拉斯加，当地居民通过传统的自给自足的生活方式与土地紧密相连。
