Sound Transmission Measurements at 8 and 16 KC in Caribbean Waters, Spring, 1949,

Abstract

Measurements of sound transmission at 8 and 16 kc have been obtained through the use of a submarine-mounted sound projector and a string of six hydrophones suspended at different depths from a surface ship. The use of a submarine-mounted projector thus provided a sound source of controllable depth, range, and frequency. Data were obtained in Caribbean waters on a cruise between Key West, Florida and San Juan, Puerto Rico during February and March, 1949. Essentially simultaneous measurements were made at 8 and 16 kc. The resulting mass of data was found to be most lucidly presented when plotted as transmission-anomaly cross-sections. These were found to have features only partially explainable from the ordinary bathythermograph trace.
