Coastal dynamics monitoring on the key areas of oil and gas development at the Barents and Kara Seas has been carried out by Laboratory of Geoecology of the North at the Faculty of Geography (Lomonosov Moscow State University) together with Zubov State Oceanographic Institute (Russian Federal Service for Hydrometeorology and Environmental Monitoring) for more than 30 years. During this period, a unique monitoring technology, which includes direct field observations, remote sensing and numerical methods, has been developed. The dynamics of thermal-abrasion coasts are directly linked with climate and sea ice extent changes. We have also evaluated the influence of local anthropogenic impacts on the dynamics of the Arctic coasts. As a result, a method of forecasting the dynamics of thermal-erosion coasts taking into account climate changes has been developed.
