Using GIS technologies to create a scientific and information geoecological base in Western Yamal to identify the effects of climate change

Abstract

Climate change and marine conditions affecting the formation and evolution of the permafrost zone of the shelf and the continental margin of the Russian Arctic, is an urgent problem for the Russian sector of the Arctic. The results of long-term monitoring of the permafrost zone clearly demonstrate the degradation of frozen rocks both in continental and in subaquatic conditions of the western sector of the Russian Arctic. The coastal-marine region of Western Yamal is the most vulnerable and therefore model territory with climatic changes. The assessment of the dynamics of the geoecological conditions of the coastal-marine region of Western Yamal with climate change is impossible without a GIS component. At the same time, the study of geoecological processes and their mapping becomes especially relevant for the preparation of long-term plans for the development of climate-dependent branches of economic activity. The permafrost zone of the western sector of the Russian Arctic remains poorly understood. Climate warming in the western sector of the Russian Arctic is recorded after 1970. There is an increase in air temperature and duration of the warm period, a change in the amount of precipitation, and an increase in snow thickness.
