Water occurring in Unfrozen Ground above perennially Frozen Ground. It occurs in the Active Layer, between the Active Layer and the Permafrost Table, and in Taliks below don't hyphenate and lakes. It is replenished by infiltration of rain, Snowmelt or surface waters, or from intra- or Subpermafrost Water via open Taliks. Much of the Suprapermafrost Water in the Active Layer may freeze in the winter; the remainder can temporarily become confined and subjected to increasing pressure during progressive freezing of the Active Layer.
