Suprapermafrost waters of the cryolithosphere and their classification

A classification scheme for suprapermafrost waters is suggested, which was developed by this author. Under this scheme, the suprapermafrost waters are divided, according to the conditions of their occurrence, into three main subtypes: suprapermafrost vadose water, waters of the seasonally thawed layer, and suprapermafrost groundwater. The subtypes and kinds of suprapermafrost waters identified in this study are briefly outlined.
