    dct:description """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.\r
\r
A spatial modelling framework was used to estimate where thermokarst landscapes are currently located or could develop.The framework weighed the perceived relative influence of landscape characteristics including ground ice content, sedimentary overburden thickness, permafrost zonation, terrestrial ecoregion, topographical roughness, and the presence of permafrost peat soils (histels). Weights of landscape characteristics for determining the regional coverage were decided through an expert elicitation, which included input from all co-authors as well as from members of the Permafrost Carbon Network.\r
\r
More information on database processing and properties can be found in the product guide.\r
