Study of the lakes dynamics and processes of permafrost new growth in the Yamal peninsula, on the basis of aerospace observations data
The analysis of aerospace survey archives data and terrestrial observation materials has revealed in Yamal Peninsula the widespread processes of lakes drainage and new permafrost growth, with high ice content. Spatial connection of the lake-drainage with the Peninsula tectonic structure peculiarities and the pattern of underground thick ice deposits is verified. It is shown that the main cause of modern lake-drainage in the Yamal Peninsula is a wide-spread development of thermo-destructive processes which leads to the rapid ravines and gullies system formation along linear glacial zones.
