High Frequency Propagation Studies in the Coastal Environment

Abstract

To learn how small scale physical and biological processes contribute to the scattering of high frequency acoustic signals. To understand the relationship between bubble distributions, turbulent flows and related phenomena and the scattered acoustic signal. To develop models of these processes. To develop improved measurement approaches, carry out high frequency propagation experiments in shallow water environments and interpret the results in terms of contributions due to bubbles, waves, turbulent velocity and sound speed fluctuations.
