The article presents the results of a study of the deep factors’s influence on the spatial and temporal patterns of the ice cover formation of the Arctic shelf cryolithozone. The main source of ice information is satellite remote sensing data, which are necessary to solve scientific and practical problems of development of the Northern Sea Route. The paper presents a comparative analysis of data from satellite monitoring of the ice cover thickness with petrophysical sections of the Earth’s crust and lithospheric magnetic anomalies measured on the CHAMP satellite. To identify the structural features of the lithosphere that affect the formation of the ice cover, petrophysical sections crossing the zones of accelerated ice melting were constructed: density–based on gravity anomalies, magnetic–based on anomalies of the Earth’s magnetic field module. In the zones of potential accumulation of gas hydrates in the Arctic seas of the Northern Sea Route, channels of influence of the endogenous fluid-dynamic factor have been identified. This made it possible to make a forecast of the areas of occurrence of deep origin emergencies caused by the migration of mantle fluid flows. Based on the analysis of deep petrophysical sections in the zones of gas hydrate near the Northern Sea Transport Corridor, the authors have identified through taliks at the exit of the thermofluid channels. In areas of the Laptev Sea, where, according to geochemical studies, methane emissions of deep genesis have been confirmed, the subvertical trajectories of fluid flows approaching the seafloor from a depth of 25–30 km have been traced in deep sections. During the work, an assessment was made of the most likely location of endogenous natural hazards in areas of gas hydrates accumulation and in areas with a high level of gas saturation of bottom sediments in the Barents, Kara, East Siberian, and Chukchi seas and the Laptev Sea. The study of the influence of the fluid-dynamic factor on the Northern Sea Transport Corridor ice regime will optimize the choice of the safest transport and logistics routes for uninterrupted year-round navigation.
