Authors: Gubaidullin M. G., Turobova T. A.

Based on the review of the published data, the article analyzes the study of the problem of oil pollution migration in the upper part of the geological environment in the conditions of the Far North, where the movement of oil pollution occurs mainly in the layer of seasonal freezing and thawing of the cryolithozone. The factors influencing the spreadability and transport of oil, including the focus on the processes of formation of possible migration routes into frozen rocks are considered.

A Modern Condition and Anthropogenic Effects in the Course of Development of the Polar Landscapes of Russia

Authors: Skrylnik G. P., Sorokin P. C.

The landscapes of polar countries are neither young nor secondary. An external shape and internal composition of polar landscapes are created as a whole by permafrost (continuous, faltering with taliks and island). In some cases, under unfavorable conditions, its own destructive influences on landscapes are strengthened by endodynamic risks (first of all, by seismicity flashes from 1 to 2 points).
