Dynamics and Stability of Acoustic Wavefronts in the Ocean

Abstract

The long-term goals are to: develop a method of modeling sound propagation in an environment with multi-scale inhomogeneities, which preserves the efficiency and intuitive qualities of the ray theory but is free from spurious environmental sensitivity and strong perturbations associated with ray trajectories; and investigate and quantify effects on underwater acoustic wavefronts of internal gravity waves, sea swell, spice, and other small-scale processes in the water column.
