Abstract

In this presentation we have modeled sound propagation in regions having range dependent sound speed profiles. Three scenarios are considered, 1) sound propagation through an internal hydrodynamic wave, 2) long distance sound propagation in a region having a hot core vortex, and 3) sound propagation in a region characterized by a set of solitons.
