Abstract : Characterization of sound propagation in shallow water requires a detailed understanding of the propagation processes and environmental properties, and how they are linked. This report contains three separate sections that address the effects of range dependence, sediment transverse isotropy, and high attenuation on acoustic propagation in shallow water. The investigations described are theoretical and numerical, and are based on the method of coupled local modes. (AN)
