Аннотация:Coastal dynamics monitoring on the key areas of oil and gas development atthe Barents and Kara Seas has been carried out by Laboratory of Geoecology of the North atthe Faculty of Geography (Lomonosov Moscow State University) together with Zubov StateOceanographic Institute (Russian Federal Service for Hydrometeorology and EnvironmentalMonitoring) for more than 30 years. During this period, an up-to-date monitoring technology,which includes direct field observations, remote sensing and numerical methods, has beendeveloped. The results of such investigations are analyzed on the example of the Ural coast ofBaydaratskaya Bay, Kara Sea. The dynamics of thermal-abrasion coasts are directly linked withclimate and sea ice extent change. A description of how the wind-wave energy flux and theduration of the ice-free period affect the coastal line retreat is provided, along with a methodof the wind-wave energy assessment and its results for the Kara Sea region. We have also evaluated the influence of local anthropogenic impacts on the dynamics of the Arctic coasts.As a result, methods of investigations necessary for obtaining the parameters required for theforecast of the retreat of thermoabrasional coasts have been developed.
