Modeling the Effects of Internal Waves on Long-Range Propagation
Abstract
This project aims to understand the fluctuations in low frequency (100 Hz, for example) acoustical propagation in the ocean over long distances (50 km to thousands of km.), as well as other effects of internal waves and other small-scale variability in the speed of sound. The objective is to model results of recent low-frequency, deep-water acoustic-propagation experiments, constraining the model environment from the measurements of those environments. Phenomena such as intensity fluctuations, deep arrivals, and spatial correlations are of more concern than travel time fluctuations, as the physics of travel time fluctuations is much better understood. This work is continuing, currently under a grant with Dr. Jim Mercer as PI.
