Submarine Sand Dunes on the Continental Slope in the South China Sea and Their Impact on Internal Wave Transformation and Acoustic Propagation

Abstract

The long-term goal is to enhance our understanding of coastal oceanography by means of applying simple dynamical theories to high-quality observations obtained in the field. Objectives: * Conduct a field program in the South China Sea to determine the combined impact of large submarine sand dunes (hereafter "dunes") and large amplitude nonlinear internal waves (hereafter "waves") on sound transmission over the Chinese continental slope near Taiwan * Determine how the nonlinear internal waves (NLIW) and tides interact with the seafloor to form and maintain the dunes * Study how enhanced bottom roughness in the dune field affects energy dissipation in the NLIWs and tides as they shoal over the upper continental slope.
