Abstract:

   During the echo-survey at the open part of the bay of Laspi, a path of more than 25 km was passed. The area covered by acoustic observations was, approximately, 41,5∙103 m2. In total, 5 acoustic anomalies were revealed, identifying the presence of gas bubble streams in the depth range 14 – 24 m. It is assumed they are originated from the same deep source of hydrocarbon gases from which methane emits at the apex of the bay.

Keywords: Black Sea, gas bubble streams, hydroacoustics, the bay of Laspi.
