Use of Sonar Systems to Detect Areas of Gas Discharge of the Seabed

The study presents and analyzes the experimental results of geological and geomorphological observations in some marine areas with active gas emission from bottom sediments. The study was carried out using an instrumental complex of geophysical sonar equipment, which included a subbottom profiler and side scan bathymetric sonar that uses an interferometric method for measuring depths in the field of view. The results confirm the possibility of using the complex to classify the seabed morphology and control the processes of gas unloading. The use of sonar equipment for remote seabed mapping during satellite observations can be used to interpret the results of satellite remote sensing of the atmosphere.
