Catchment‐Scale Permafrost Mapping using Spring Water Characteristics
This study presents a method for mapping the spatial distribution of mountain permafrost based on the chemical‐physical characterisation of spring water in a 36 km2 high‐elevation catchment in the Eastern Italian Alps. Water temperature, electrical conductivity and isotopic composition (δ2H and δ18O...

This study presents a method for mapping the spatial distribution of mountain permafrost based on the chemical‐physical characterisation of spring water in a 36 km2 high‐elevation catchment in the Eastern Italian Alps.

Existing evidence of permafrost enabled the areas upslope of springs to be classified into two categories of permafrost occurrence (probable permafrost and no permafrost) and used to determine the most suitable tracer for permafrost mapping.
