Acquisition of Acoustic Source to Augment Navy Sonars for Mapping Sound Speed and Temperature with Tomography

Abstract

My long-term goal is to get enough data from the ocean so that its physical and acoustically induced fluctuations can be understood from theories and models. I hope to use this information to help the Navy with its operations. want to demonstrate that passive and active Navy sonars can be used to map the sound speed fields by means of acoustic tomography. The Navy puts sound into the water and has passive arrays, both towed and fixed, that could be used to measure the travel times of acoustic multipath for subsequent inversion for the sound speed field.
