Description :
For long-term monitoring of the active layer it is important to understand spatial variation, both between sites (inter-site) and within each site (intra-site). The primary goals of the research reported here are : to refine estimates of the spatial scale of variation of thaw depth to determine the optimal sampling distance for the 2 major physiographic provinces of northern Alaska, the Arctic Coastal Plain, and Arctic Foothills; to compare the applicability, ease of implementation, and output of a hierarchical analysis of variance with variogram analysis for describing spatial variation.
