Acoustic Propagation Studies in the Windy Islands Soliton Experiment (WISE), September 30, 2006.

摘要

Our long-term research objectives are: (1) Characterization of meso- to internal-wave-scale oceanographic processes which influence broadband sound transmissions in a coastal environment. Central to the characterization are the formulation of accurate forward relations and the quantification of the sensitivities and variability of the various observable acoustic quantities in relation to environmental differences and changes. (2) Development and improvement of high-resolution tomographic inverse techniques for measuring the dynamics and kinematics of meso- and finer-scale sound speed structure and ocean currents in coastal regions. (3) Understanding of three-dimensional sound propagation physics in a highly variable coastal region, including horizontal refraction and azimuthal coupling, with the ultimate goal of accurate prediction of acoustic propagation within this complex environment. (4) Characterization of the variability in the acoustic propagation over long ranges in the deep basin of the South China Sea (SCS), in the presence of large non-linear internal waves and solitons.
