Coupled perturbed modes and internal solitary waves.

Coupled perturbed mode theory combines conventional coupled modes and perturbation theory. The theory is used to directly calculate mode coupling in a range-dependent shallow water problem involving propagation through continental shelf internal solitary waves. The solitary waves considered are thermocline depressions, separating well-mixed upper and lower layers. The method is fast and accurate. Results highlight mode coupling associated with internal solitary waves, and mode capture or loss to and from the discrete mode spectrum.

Coupled perturbed modes over a sloping penetrable bottom.

The development of coupled perturbed mode theory--the combination of conventional coupled modes and perturbation theory for problems of sound speed range dependence--is extended using a transformation of the normal modes to include a range-dependent penetrable bottom. The result is a fast, direct, and accurate range-dependent modal solution of the acoustic field in the water column. The method is applied to upslope propagation in shallow water wedge waveguides.
