Ocean Acoustic Propagation: Fluctuations and Coherence in Dynamically Active Shallow-Water Regions

Abstract

The goals of this research program are to understand the nature and causes of acoustic signal fluctuations in the shallow water environment (i.e. the physical mechanisms). Under the auspices of this grant we have refined a three-dimensional computational acoustic modeling tool, have used computations and theories to make predictions of fluctuating acoustic behavior in shallow water, and have compared data from three field programs with the computations and theories Research findings have been published in reports, journal articles, and conference proceedings papers.
