Description :
Recent research in North America supports earlier Russian conclusions about the existence of a transition zone. The transition zone is ice-enriched, and functions as a buffer between the active layer and long-term permafrost by increasing the latent heat required for thaw. This zone has an impact on the formation of a cryogenic soil structure, and imparts stability to permafrost under low-amplitude or random climatic fluctuations. Research treating permafrost-climate interactions must be based on a more realistic three-layer model. This paper is focused on the upper part of the transition zone known as the transient zone.
