On the structure of the acoustic field in the sea containing a developed bubble layer near the surface

Abstract

Taking into account new experimental data on the distribution of bubbles in sea water, it is shown that the influence of a near-surface layer of bubbles on the structure of the spatial decay in the propagation of sound can be significant at fairly typical concentrations of bubbles in the near-surface layers of the ocean. In the presence of bubble clouds, a spatial restructuring of the field energy structure is observed, in which the main effect of the bubbles is concentrated at small distances, at the same time not affecting the sound attenuation at large distances.
