项目摘要

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 more than 200 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 thickness, 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.

该奖项将支持环极活动层监测（CALM）计划的继续，作为北极观测网络（AON）和北极环境变化研究（ESTA）的一个组成部分。由200多个站点组成的活动层网络是唯一一个协调一致的标准化观测方案，采用标准测量协议，旨在观测和探测高纬度土壤季节性解冻和冻结动态的十年变化。本研究的“智力价值”在于需要在同一地点和不同地形类型和地区的活动层厚度，地面温度和解冻沉降测量的长期时间序列，以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、水文和冻土模型。教育和推广是CALM“更广泛影响”的重要组成部分。该项目将提供从小学到博士后的实地经验和教育参与机会。当地人，主要是土著人，将协助在偏远地点进行观测。CALM将继续将数据纳入其基于网络的数据库。
