Analysis of Data from the South China Sea Upper Slope Sand Dunes Acoustics Experiment

Abstract

Our long-term research goals are: (1) the characterization, understanding, and prediction of the statistics (mean, variance and coherence) of low-frequency acoustic signals and ambient noise in the littoral zone. The signal statistics are primarily influenced by the ocean variability and bottom properties. The noise statistics are influenced by atmospheric forcing and shipping in addition to the ocean and bottom variability; (2) the development and improvement of inverse techniques for measuring the dynamics and kinematics of meso-and finer-scale sound speed structure and ocean currents in coastal regions; (3) the understanding of three-dimensional sound propagation physics including horizontal refraction and azimuthal coupling and the quantification of the importance of these complex physics in the prediction of sound signals transmitted over highly variable littoral regions.
