High Frequency Acoustic Propagation Studies

Abstract

The long-range scientific objective of our program is to understand the propagation of high frequency sound in the sea and the physical characteristics of the medium that contribute to it. The objective of this study is to perform a series of experiments at sea in order to measure the relationship of thermal microstructure to acoustic propagation in a shallow water coastal environment. An important question that one would like to answer in understanding the propagation of high frequency sound and its variability is what are the underlying physical causes for this variability. The goal of this project is to perform simultaneous measurement of spatial temperature microstructure and to correlate this microstructure and its change to variability in acoustic propagations.
