Computer database with the satellite coordinates and electron echograms was created and high-speed hardware-software interface for registration and proceeding the echograms in the real-time regime for the search and quantitative estimation of the gas yield from the Black Sea bottom was developed. Geographical zoning was conducted and methane inflow into the water medium and atmosphere from the stream gas discharge grounds from the Black Sea bottom was determined. It was calculated, that methane emission into the hydrosphere from the Black Sea bottom ground makes integrally 25 mln m3 year-1, and 0,4 mln.m3 year-1 (1,9%) of that achieves the atmosphere.
