Abstract

The article shows that acoustic research is based on the sound backscattering method. Acoustic methods make it possible to estimate the contribution of sufficiently large phase inclusions that make up heterogeneous heterogeneities in the sea layer: large plankton (mainly zooplankton), fish, suspended matter, gas bubbles, etc. The described method of acoustic sounding makes it possible to study the small-scale structure of the aquatic environment in the shelf part of the sea and its spatio-temporal variability associated with the manifestation of internal waves, the presence of bubbles, plankton, turbulent formations, solid suspensions.
