Changes in temperature regime and associated effects on anthropogenic salinity of permafrost (Central Yakutia).

Author(s) : ANISIMOVA N. P., KURCHATOVA A. N.

Summary

High salinity is not limited to the active layer but is observed along the entire depth of foundations. Sometimes lenses of highly mineralised negative temperature groundwater (cryopegs) are formed. Research of formation of anthropogenic salinity, the processes of cryopeg vertical and horizontal migration shows that there is a direct correlation between temperature regime and salinity of the bearing soils. Intensive salt localisation occurs within the layer of considerable annual fluctuations of soil temperature.
