POCKMARKS, SEEP SOURCES, AND DEGASSING PROCESSES IN THE POLAR REGION STRUCTURES.

The new results of the frequency-resonance technologies application for the study of the sources and processes of seeps and pockmarks formation in the Arctic and the North Sea are considered. The study of the methane seeps and pockmarks fields shows that the intensity and dynamics of their formation depend on the inflow of gas fluids from deep sources because of a result of active degassing processes. The use of FR-sounding technologies allows us to remotely determine the spatial regularities of intense gas emission zone formation and the probable depth of geological sources of migration. The seep and pockmark field study results confirm the crust-mantle gas fluids' influence on the nature and degassing processes features in the structures of the continental margins. Modern degassing centers' studies have confirmed the presence of zones of active migration of gases into the atmosphere, which is an important factor in the dynamics of global climate change processes. The experience of FR- technologies used in the fields of methane seeps and pockmarks study in the structures of the Arctic polar seas showed their versatility and the possibility of their use in the study of gas emissions in structures of different regions.
