PHYSICS OF SOUND IN THE SEA is the distillate of the brightest, most creative minds in the underwater acoustics community during World War II. The primary wartime effort to understand the underwater acoustic environment for the purpose of submarine and antisubmarine warfare was directed by the Subsurface Warfare Division of the National Defense Research Committee. This division organized and directed programs and studies to combine theory with experiment in order to characterize underwater sound transmission for immediate wartime application. Participating in these studies were staff members...
