Patterned-Ground 10 x 10 m Grids (Raynolds et al. 2005)

This mapping includes six sites on the North Slope of Alaska. The sites are located along the Dalton Highway and in the Prudhoe Bay Oilfield area, forming a north-south transect across the climate gradient of the North Slope. From South to North, the sites are Happy Valley, Sagwon, Franklin Bluffs, Deadhorse, West Dock and Howe Island. At each site, 10 x 10 m grids were mapped to characterize the heterogeneity of vegetation in the patterned ground ecosystems created by soils, climate and vegetation interactions. This work was funded by the US National Science Foundation Biocomplexity grant OPP-0120736.

The maps were hand-drawn in the field, and later digitized as shapefiles. Thaw depth, snow depth, and NDVI were sampled on the grids, usually every meter. The vegetation mapping legend is similar to that used for the Upper Kuparuk River map: http://www.arcticatlas.org/maps/themes/uk/ukvg
