Under study was the temperature regime of frozen soils situated along the southern boundary of cryolithozone in the North-East of European Russia. In southern tundra the frozen soils with the cold temperatureregime are confined to peat and mineral parent materials. The seasonaland long-term temperature dynamics in seasonal thawing and underlying permafrost-affected layer is shown. The frozen soils are characterized by the main temperature indices.

Keywords: temperature regime, cold frozen soils, permafrost-affected rocks, seasonal-thawing layer.
