Three-Dimensional Shallow Water Acoustics

Abstract

Both physical oceanographic processes and marine geological features in continental shelves and shelfbreak areas can cause lateral heterogeneity in medium properties, so horizontal refraction of sound can occur and produce significant three-dimensional (3-D) sound propagation effects. The long-term goals of this project are targeted on understanding the 3-D acoustic effects caused by the environmental factors existing commonly in the continental shelf and shelfbreak areas, such as slopes, submarine canyons, surface waves, internal waves and shelfbreak fronts.
