摘要：

A correlation between acoustical nonlinearity, sound absorption, and scattering in a subsurface bubble-saturated layer is established. A model of effective parameters of a bubbly liquid is developed that allows one to obtain results coinciding with experimental field studies. It is shown that "bubbly clouds" under the sea surface increase substantially the sound scattering and the nonlinear acoustic parameter of the seawater.
