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 50-4000 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 continue to refine and improve on a statistical inference approach and to apply the method to the analysis of acoustic data taken in the Shallow Water 2006 SW06 experiment. The second objective was to develop and test a new coupled mode approach that will serve as the basis for an advanced seabed attenuation analysis of SW06 data.
