The paper presents the results of the research on contemporary permafrost dynamics associated with climate changes in Eastern Chukotka region (Chukotsky peninsula) and its impact on indigenous peoples? communities. The studies are based on the field monitoring works and geodetic measurements within several settlements as well as remote sensing data analysis and statistical results processing. The reasons of permafrost exogenous processes dynamics were indicated. The research was shown that the main threats for the...

The permafrost zone (cryolithozone) is undergoing now an intensive anthropogenic influence. The strongest influence of the linear structure could be heating of the upper part of the ground layer, thawing of ice inclusions, weakening of the soil and surface subsidence. The strongest risk for constructing engineering structures within the southern part of the cryolithozone results from peatlands because of peat soil with high ice content. The aim of this work is revealing main interpretation criteria of peatlands co...

The Arctic coasts are complex and actively changing systems, their erosion rates varying in time and space. Due to global warming and its thermal and wind-wave effects, there is a tendency of increase in coastal erosion rates. Understanding of the interaction between permafrost and sea is important to disclose the background of active development of natural resources in the Arctic coastal zone (construction of coastal facilities, offshore pipelines, etc). In the present study, coastal dynamics of the Western Russi...

The present study investigates spatial and temporal variability of permafrost coasts? retreat rates at the offshore gas pipeline crossing of the Western Yamal Peninsula coast under conditions of climate change and local human impact. Erosion of permafrost coasts is determined by a combination of hydrometeorological factors, such as wave height, air and water temperature, ice-free period duration, and the features of coastal structure: cliff height, ground ice content, type of sediments. Coastal dynamics were studi...

The paper presents information about the mineral resource base of the Republic of Sakha (Yakutia)-one of the richest regions of Russia in minerals and severe climatic conditions of their development, the presence of almost universal permafrost causes a particular vulnerability of the environment in mining. In this regard, the methods and results of studies of the geoecological state of the landscape in the development of Geosciences, including space surveys of mining operations, the regime of their restoration by ...
