摘      要：The experimental study of the seepage processes’sources formation in structures of the Arctic Region was carried out using modified methods of frequency-resonance(FR)processing and decoding of satellite images and photographs with the vertical scanning of the *** newly obtained results show that the intensity and dynamics of the methane seeps and pockmarks fields’formation depend on active deep degassing processes in the continental margin *** use of direct FR-sounding technologies allows for determining the probable origin and depth of geological sources of gas migration at marginal migration centers in Greenland,and Norwegian and Barents *** results confirm the crust-mantle gas fluids’influence on the nature and degassing processes features in the scan points of polar marginal *** data are important arguments in favor of the“volcanic modelof various structural elements formation in this and other *** FR technologies data also showed a possibility of seeps use as shallow and deep hydrocarbon field indicators in gas emission *** independent data can be used in compiling models of the deep lithosphere structure and possible mechanisms of abiogenetic hydrocarbon formation in Arctic margin *** authors suppose that hydrocarbons through deep channels migrate(from 57 km deep)to the upper crustal horizons where their fields can *** this migration,gas seeps and pockmarks are formed on the sea bottom and part of the gas can migrate into the *** show that basaltic volcanoes in Greenland scan points can be the real channels through which hydrogen migrates to the upper crustal horizons and further into the *** gas migration in Arctic seepage areas can be an important factor in the global climate change processes.
