ONR Basic Research in Ocean Acoustics for FY03

Abstract

The long-term goal of this research is to advance the knowledge base for low frequency sound propagation and scattering in complex shallow water environments. Specific goals include the discovery of the underlying physics for [1] the frequency dependence of complex sound speed in marine sediments and [2] reverberation due to marine sediments. A key challenge is to be able to ascertain these properties of the seabed from measurements that involve considerable coupling of the seabed acoustics to the properties of the water column whose properties often possess a significant degree of uncertainties in a specific experiment.
