THE DETERMINATION OF SOUND VELOCITY GRADIENTS IN THE OCEAN BY ACOUSTIC MEANS,
Abstract
The goal of the study was to assess the feasibility of determining the sound velocity profile of the ocean by acoustic means. Of particular interest was the determination of the velocity gradient of the surface layer which is subject to large variations both geographically and seasonally. Lesser importance was attached to the determination of the velocity gradients of the deep layers which are more stable and thus more predictable. This fundamental approach in this study has been to relate the velocity gradient to the observed decay rate of the surface reverberation and the time at which it was observed. The theory presented predicts that observable differences in the reverberation decay rates exist for different positive velocity gradients. Some of the important environmental factors which must be known before meaningful interpretations from the observed data can be made are pointed out. The study outlines an experiment that will provide the data necessary to corroborate the theory presented. (Author)
