title: Physical principles of creation hydroacoustic barrier gas jet exit from the seabed
abstract: The aim of the work is to determine the physical mechanism for generating acoustic images of jet gas exits from the seabed. To achieve this goal, the dependence of the sound scattering in water on the frequency of sound and bubble diameter is investigated. The problem of formation of gas streams of methane, which is released from the seabed - natural acoustic barrier, is considered. It has been shown that more than 5,000 gas exits have been identified in the Black Sea. The spatial scales of gas
