Shallow Water Propagation and Surface Reverberation Modeling

Abstract

The primary long term goals of this program have been to measure and model high frequency acoustic propagation and scattering near the sea surface. Processes of particular interest are scattering from surface gravity waves and the effect of whitecaps and bubble clouds on underwater acoustic communications. Secondary long term goals were to 1. exploit measurements of breaking wave noise and photographic images of whitecaps to infer bubble cloud populations at the sea surface and 2. study ambient noise in coastal Arctic regions.
