Ultralong Underwater Sound Propagation

 

the propagation of acoustic vibrations in seas and oceans over great distances (on the order of thousands of kilometers) by means of a natural underwater sound channel. This phenomenon was discovered independently by the American scientists W. M. Ewing and J. Worzel in 1944 and by the Soviet scientists L. M. Brekhovskikh, L. D. Rozenberg, B. I. Karlov, and N. I. Sigachev in 1946; the Soviet scientists received the State Prize of the USSR in 1951 (seeHYDROACOUSTICS).
