Map of Arctic Thermokarst Landscapes

Dominant or co-dominant thermokarst landscapes within the northern boreal and tundra circumpolar permafrost region (Olefeldt et al., 2016).

Arctic Circumpolar Distribution and Soil Carbon of Thermokarst Landscapes, 2015

This data set provides the distribution of thermokarst landscapes in the boreal and tundra ecoregions within the northern circumpolar permafrost zones. This dataset provides an areal estimate of wetland, lake, and hillslope thermokarst landscapes as of 2015. Estimates of soil organic carbon (SOC) content associated with thermokarst and non-thermokarst landscapes were based on available circumpolar 0 to 3 meter SOC storage data.
