Cryptic ground ice conditions in permafrost and northern agricultural expansion

Cryptic ground ice conditions in permafrost and northern agricultural expansion Permafrost conditions are often heterogeneous and concealed beneath the surface, becoming evident only when thawing occurs. Melissa Ward Jones discusses these challenges and highlights a new publication that identifies ice wedges for the first time in the Yukon-Kuskokwim Delta region of Alaska. Permafrost conditions, including ground ice content, can be highly heterogeneous, but are hidden below the ground surface and are often only “revealed” when permafrost begins to thaw. Here, I discuss these potential challenges and highlight a new publication that found ice wedges in the Yukon-Kuskokwim Delta region of Alaska for the first time.
