Brief description, advantages, further prospects for application.

The hydrological conditions, spatiotemporal and seasonal variability of sound velocity fields, characteristics of the bottom and surface, and processes of sound reflection and scattering at interfaces (surface and bottom) in areas of expected hydrocarbon deposits, including those near the island, were studied. Zmeiny, the characteristics of the medium and its random small-scale inhomogeneities, sound velocity profiles and their spatio-temporal variability, the features of their fine-structure formations, sound velocity fields and their fine structure, the processes of propagation and scattering of sound under conditions of random small-scale inhomogeneities of the beam during sound scattering on inhomogeneities environment, interfaces and movement of receiving-emitting transducers, multipath propagation of acoustic signals in the PPFM in different hydrological seasons at different depths of the sea, the processes of formation of received signals during multipath propagation and distortion of their phase, frequency and characteristics, scattering of signals over time (multipath propagation) and in frequency (Doppler shift of the frequency spectrum) in different hydrological seasons at different depths and at different waves, the principles for constructing hydroacoustic channels have been developed. cash, working in the conditions of such distribution. The performed works make it possible to create information hydroacoustic channels that work effectively in conditions of variability in the characteristics of the medium of propagation and scattering of sound at its boundaries and inhomogeneities.
