Abstract
The Black Sea is a unique geo-ecosystem with special hydrological, geochemical, geological and biotic subsystems. The environmental ecological subsystems of the Black Sea geo-ecosystems, namely marine aerial, aquatic and marine geological ecosystems, have certain natural features of internal ecological conditions. Wide development of gas- and mud volcanic processes in the deep sea zone of the Black Sea and the dissemination of gas emissions mainly of methane composition have a huge impact on the material composition of the components, the physical-mechanical and engineering-geological conditions. This necessitates monitoring studies of the state of the geological environment of the Black Sea because of the need to identify and understand the features of the temporal and spatial dynamics of its degassing processes. A comprehensive study of gas volcanism, gas discharge and gas hydration phenomena of the deep sea zone of the Black Sea, showed that submarine mud volcanoes and methane eruptions are not only a reliable indicator of prospects for the detection of offshore hydrocarbon fields, but also is a very important factor of the geosystem existence. In the development of special technologies, reactive gas emissions can become a promising source of hydrocarbons as an energy resource.
