Annotation

The sound propagation in the sea in the presence of a near-surface layer of bubbles is discussed with the use of the latest experimental results for the bubble size distribution function g(R) obtained at different wind speeds and different States of the sea surface. It is shown that the presence of dissipation in the near-surface layer of bubbles with an increase in the volume concentration greater than 10-6 can lead to a significant restructuring of the acoustic field structure. Keywords: sea water, bubbles, sound absorption.
