The Circumpolar Active Layer Monitoring Network--CALM III (2009-2014): Long-term Observations on the Climate-Active Layer-Permafrost System

该奖项由2009年《美国复苏和再投资法案》(公法111-5)资助。该奖项将支持作为北极观测网络(AON)和北极环境变化研究(SEARCH)组成部分的环极活动层监测(CAMP)计划的继续。由168个站点组成的活动层网络是使用标准测量协议进行的唯一协调和标准化的观测计划，旨在观察和检测高纬度土壤季节性融化和冻结动态的十年变化。这项研究的“智力价值”在于，需要在相同地点、不同地形类型和地区测量活动层深度、地温和融化沉降量的长期时间序列，以便确定空间变化的尺度，建立趋势，并验证模型。这些数据还将有助于详细的过程研究，以及验证和开发气候变化、生态学、水文学和地球冰晶模型。教育和外展是平静的“更广泛影响”的重要组成部分。该项目将为从小学到博士后的各级提供实地经验和教育参与的机会。当地，主要是土著居民，将协助在偏远地点进行观测。Calm将继续将数据纳入其基于Web的数据库，并将所有现有数据和新数据传输到怡安档案Cadis。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This award will support the continuation of the Circumpolar Active Layer Monitoring (CALM) program as an integral part of the Arctic Observing Network (AON) and the Study of Environmental Arctic Change (SEARCH). The active-layer network of 168 sites represents the only coordinated and standardized program of observations using standard measurement protocols designed to observe and detect decadal changes in the dynamics of seasonal thawing and freezing in high-latitude soils. The 'Intellectual Merit' of this study lies in the need for long-term time series of active layer depth, ground temperature, and thaw settlement measurements at the same locations and across diverse terrain types and regions in order to identify scales of spatial variation, establish trends, and validate models. The data will also contribute to detailed process studies, and validating and developing climate change, ecology, hydrology and geocryology models. Education and outreach are essential components of the 'Broader Impacts' of CALM. The project will provide opportunities for field experience and educational participation at levels ranging from elementary school through postdoctoral. Local, predominantly indigenous people, will assist with the observations at remote sites. CALM will continue to incorporate data into its Web-based database, and transfer all existing and new data to the AON archive CADIS.
