EFFECT OF WARM EDDY ON LOW-FREQUEMCY SOUND PROPAGATION IN THE EAST/JAPAN SEA
Abstract: It has been known that sound waves in the sea generally propagate under the influence of sea surface wave, water depth, sound speed profile, sea floor sediment, etc. In particular, an abrupt change of the sound speed profile with depth in an eddy can greatly affect the sound propagation.
