Permafrost thaw monitoring in Denali National Park: Thermokarst transect surveys 2013-2023

This dataset contains variables measured at thawed, ice-rich permafrost sites in Denali National Park and Preserve. Transects were established at seven sites in the Toklat river basin in 2013 to understand how ecosystem characteristics changed following permafrost thaw. Transects were co-located with known thaw subsidence (thermokarst) or erosional features and run from outside (relatively undisturbed tundra) through the feature. These data represent a long-term monitoring project of permafrost and ecosystem characteristics, surveyed initially in 2013 and re-surveyed 10 years later in 2023.
