Analysis of South China Sea Shelf and Basin Acoustic Transmission Data

摘要: Abstract : My long-term research goals are: (1) The characterization, understanding, and prediction of the statistics (mean, variance coherence) low-frequency acoustic signals ambient noise in littoral zone. signal are primarily influenced by ocean variability bottom properties. atmospheric forcing shipping addition to variability. (2) development improvement inverse techniques for measuring dynamics kinematics meso finer-scale sound speed structure currents coastal regions. (3) understanding three-dimensional propagation physics including horizontal refraction azimuthal coupling quantification importance these complex transmitted over highly variable This is a three-year (2009-2011) project complete analysis both shelf basin data collected from Northeastern South China Sea (NE SCS) during Windy Island Soliton Experiment (WISE). These were between April 2005 October 2006. objectives twofold: first study characterize supertidal-to-seasonal-scale impacts transbasin nonlinear internal waves on long-range transmission loss. second understand quantify observed level basin. objective constitutes primary focus my effort FY10.
