The methodology for creating a scenario for the development of the environment of the Kara shelf for the last 125 thousand years is considered. A scenario in the form of a curve of the dynamics of rock temperature was developed with reference to the version of existence of large ice sheets on the shelf in the Late Pleistocene. The fragments of the scenario for the periglacial and glacial parts of the shelf are given. They allow us to visualize a significant difference in the conditions of permafrost formation within these areas and use the results of mathematical modeling in these scenarios for geocryological mapping.

The results of studies on the dynamics of the sea depths on the shoals, accumulation and freezing of coastal and alluvial-marine sediments, changes in climate and ice coverage are summarized. It is shown that recent warming and reduction of ice cover activates the syncryogenesis of accumulating coastal-marine sediments. The most significant result of this process is the emergence of islands on banks and shallows, where previously bottom thermal abrasion and deepening of the seabed dominated. The arguments in favor of the participation of stamukhas and cryogenesis in the formation of islands are presented.

In many research papers there is evidence that bacteria from sands of the Mammoth Mountain in Central Yakutia are able to survive in 3-3,5 Ma-year-old permafrost. This fact is unique from the geocryological point of view, since so far on the plains of the Northern hemisphere are not described permafrost of this cryogenic age (continuous existence). However, the analysis of materials on paleoclimate and cryogenic indicators does not confirm this statement. The cryogenic age of the Neogene sands from the Mammoth Mountain is probably no more than c. 120,000 years.

The changes in the obliquity of the Earth's orbit and the Earth's insolation for 1 million years ago are considered according to the new Astronomical theory of Ice ages. During strong cold spans, the heat can be less in the midlatitudes than now at the pole, and during strong warming the heat can be greater in high latitudes than now at the equator. Insolation periods of the evolution of the cryosphere have been introduced. When comparing them with marine isotope stages (MIS), it is established that there is no similarity between them. For example, for an interval of 5 million years, MIS have a trend, a variable structure, and a 4.5-fold decrease in the amplitude of the oscillations.

Variations in the isotopic and chemical composition of ground ice in Quaternary sediments lays a base for reconstruction of palaeo-conditions of sedimentation and Arctic climate changes in the past. In syngenetic polygonal-ice wedges stable isotope concentration is a palaeo-indicator of winter temperatures and the chemical composition of the ice may reflect the position of the coastline in the past. A study of the isotopic composition of tabular ground ice suggests that methane of bacterial origin preserved in air bubbles in tabular ground ice in Western Siberia, negates their glacial origin.

The development of the Russian Arctic in the Pleistocene-Holocene is considered--the existence of cover glaciation and changes in the Arctic basin level. Based on the analysis of the underground ice genesis, a conclusion was drawn: 1) the cover glaciation on the plains was not to the east of the Kanin Peninsula, in the mountains there was a mountain-valley glaciation; 2) the dynamics of the sea level was determined not by glacial eustasy and glacial isostasy, but by tectonic processes in the Arctic Ocean.

In order to assess the natural risks for engineering structures, it is important to correctly assess the dynamics of the sizes of thermokarst lakes. In the statistical approach, the researcher faces certain problems, since the accumulation of statistics requires considerable time and this time is often comparable to the time of operation of the facility. As a different approach for avoiding this difficulty have been proposed methods of mathematical morphology of landscapes using remote sensing data.

On the Ural part of the Baydara bay of common processes of thermoerosion, solifluction, frost punching of soil, frost cracking of rocks and development of polygonal veins are common, active formation of developed forms of gully thermo erosion, formation of snowfields. On the adjacent sea coast, thermal abrasion processes are added to the listed processes. On the basis of the analysis of the marine processes, conditions are simulated, parameters are obtained and the change in the properties of soils. Determination of the strength and deformation properties of soils at different temperatures makes it possible to determine the stability of coastal slopes under certain climatic conditions. This makes it possible to predict the place and time of the manifestation of various slope processes in nature, their intensity and consequences.

When the glaciers appear within the permafrost area and advance into it, processes of development of glaciation and cryolithogenesis interact and form in a surrounding environment a complex of particular features that, being preserved in geoforms and sediments, serve as the very informative indicators of the past glacial and permafrost environment. It is very important with respect to solve the problem of the ice cover extension in the North-Western Siberia, and in such an aspect the authors have studied different objects generated by cold in this region. Establishing the character of links between them, and considering natural system-generating complexes at the level of integral interaction of their elements, they have concluded that intensive rock freezing widely occurred in the plain of North-Western Siberia during the Quaternary. However the conditions for ice sheets formation were absent here; only in some mountains framing the plain valley glaciers could develop.

The article discusses the main causes of deformation of buildings in Chita and the impact of degradation of permafrost on this process. The use of the first principle of construction in areas with high-ice soils, as shown by the experience of construction and operation of buildings in Chita from the 70s of the XXth, in most cases, was erroneous. It was found that the increase in the temperature of the bases as a result of leaks from water-bearing networks led to degradation of the MMP and as a consequence to deformations of buildings. One of the ways to solve this problem is the preliminary thawing of frozen soils.

Mountain permafrost is a unique object, where at a relatively short distance there is a change in the types of its distribution and temperature change. We used this fact in a field experiment with the aim of obtaining a uniform resistivity model of vertical geocryological zonality. On one of the ridges of the Altai Mountains all measurements were performed by the method of electrical resistivity tomography. It is established that two-dimensional geoelectric model of the slope inherit the mode of the changes in the structure of the permafrost--bottom-up increases the thickness and continuity of the reference high-resistivity horizon and increases the resistivity of permafrost.

The gas constituent, together with the solid and liquid phases, is one of the components of the frozen soil structure, which has been relatively poorly studied to date. At the same time, according to numerous reports from survey organizations (for example, the Lengiprotrans report for 1987), active gas emissions are recorded during drilling, sometimes leading to the ejection of the drilling tool and the appearance of a gas torch. In this regard, since the mid-1990s an "ecological" direction has been formed to study the emission of hydrocarbon gases from frozen rocks. Separate chapters are devoted to this direction in the works of Yakushev V. S., Rivkin F. M., Perlova Ye. V. It is noted that during thawing of frozen soils in summer from the surface and slopes of the coastal zones of the seas, lakes and rivers, a large supply of biogenic gases in atmosphere. There are attempts to determine the content of nutrient gases in the upper horizons (up to 10 meters) of permafrost sequences and predictive estimates of their potential emissions with an increase in the depth of seasonal thawing associated with global warming.

Experimental research on frozen dispersed deposits saturation by gas hydrates have shown, that different in granular and mineralogical compositions sediments have different conditions for hydrate accumulation and different thermodynamic conditions of hydrate decomposition. Clays represent the worst media for hydrate accumulation and existence. Nevertheless there are many observations of hydrate presence in clay-containing sediments, especially offshore. Experimental modelling of metastable hydrates decomposition in sediment sample recovered from "Yamal crater" has shown, that metastable hydrates can generate huge volumes of gas in frozen, salted clays even if negligible (tenth and hundredth of a degree) temperature rise.

In 2017 scientists from Russia and the United States conducted joint research which allowed detailing ideas about formative mechanisms of beaded channels of small rivers, that consist of lake-like pools connected by narrow runs and are widespread in permafrost regions. Despite the significant role of thermokarst in their formation, the size of the pools depends on the discharge, but does not depend on the size of the ice-wedge polygons. The location of pools in beaded meandering channel is mainly determined by the channel process. It has been established that beaded streams were quite stable over the past 60 years.

Annotation. The paper presents results of research about distribution of chemical composition of soils of the seasonal thawing layer and the near surface permafrost in the conditions of technogenic development of the cryolithozone. Technogenic influence according to geochemical data observed at depths of up to 10 m and more, with pronounced anomalies at the boundary of seasonal thawing and the transition from technogenic soils to natural ones.
