Thirteen Years of Observations at Alaskan CALM Sites: Long-Term Active Layer and Ground Surface Temperature Trends
Active layer monitoring is an important component of efforts to assess the affects of global change in permafrost environments. In this study we used data from 13 (1995–2007) years of spatially oriented field observations at a series of 16 representative Circumpolar Active Layer Monitoring (CALM) si...

In this study we used data from 13 (1995–2007) years of spatially oriented field observations at a series of 16 representative Circumpolar Active Layer Monitoring (CALM) sites in northern Alaska to examine temporal and spatial trends in active layer thickness and its relation to climatic, surface, and subsurface conditions.
