Acoustic Propagation in Continental Shelf Break and Slope Environments

Abstract

The long-term goal of the research is to increase the physical understanding of acoustic propagation in continental shelf and slope environments in the 25-5000 Hz band. This includes both the physics of the seabed and the coupling to physical mechanisms in the water column in complex range- and azimuth-dependent littoral waveguides. There were two main objectives of the current research. The first objective was to complete a final numerical implementation of a statistical inference approach based on a maximum entropy formalism. The second objective was to combine the waveguide parameter statistical inferences with geophysical data from the Shallow Water 2006 (SW06) experiment on the New Jersey continental shelf to model range-dependent acoustic data for the purpose of determining the bandwidth and range over which the effects of range-dependent inhomogenities in the sub bottom layering can be discerned.
