LANDSCAPE INDICATION OF LOCAL PERMAFROST VARIABILITY (URENGOY TERRITORY, WEST SIBERIA)

The highly variable properties of frozen ground make engineering-geological mapping in the permafrost zone impossible without cryological monitoring. Integrate monitoring of natural and technogenic landscapes has been run at test sites in southern forest-tundra and southern tundra (area of Urengoy oil-gas-condensate field) by remote sensing along with surface route and instrumental (automated) surveys and GIS mapping. As a result, a set of map models have been obtained that demonstrate obvious relationship between the landscape features and the thicknesses of peat and active layer. The studies have revealed a new indicator of the permafrost thermal state.
