The grid is located 70 km southeast of the town of Vorkuta, 67 03 56,0 N, 62 55 30,3 E. Northeast European Russia. Komi Republic. The mean annual air temperature (MAAT) is -4,2ºC, the sum of positive air temperatures (Thawing Index) totals 1100 – 1300 ºC/day, mean annual precipitation is 600 mm. Permafrost is characterized by relatively high negative mean annual temperatures (MAST) -0 -2ºC, which results in its relative instability under climate change. Island permafrost subzone. The landscape of study site is a peat plateau, located in ancient lake bed complicated with thermokarst formations and alluvial terraces. The thickness of peat deposits varies up to several meters, peat layers are underlain by Pleistocene lacustrine loams. Study area is located on the boundary between southern shrub tundra and forest-tundra.

Permafrost Zone:Unknown
Lithology:Cryic Folic Histosols and Cryic Fbric Histosols on deep peat deposits (up to 5 m)
