Thermokarst ponds as indicators of the former distribution of palsas in Finnish Lapland

Thermokarst ponds resulting from thawing of palsas were mapped in a 95 km‐long transect area in northern Finland. The spatial distribution of thermokarst was related to palsa distribution and to geographical variables using GIS techniques and multivariate spatial modelling. In our 3370 km2 study are...
