Dynamics and Stability of Acoustic Wavefronts in the Ocean

Abstract

Long-term goals: 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. To investigate and quantify effects on underwater acoustic wavefronts of internal gravity waves, sea swell, spice, and other small-scale processes in the water column.
