Abstract:

Sponsored by the office of Naval Research ONR, the Windy Islands Soliton Experiment WISE is designed to measure acoustic propagation and physical oceanography commencing April 2005-2006. As part of this experiment, two deep water moorings with acoustic transceivers source-receiver combinations will be placed in the South China Sea deep basin 160 km apart. These transceivers will transmit and receive phase-modulated signals pulses after signal processing over the year attempting to 1 capture multi-scale variability in transmission loss and 2 examine the progression of internal tides within the basin through tomographic inverse techniques. Acoustic arrival structure modeling was conducted to discern whether a detectable and resolvable signal was to be expected and for signal design. Using a stochastic inverse approach, the inversion was used to determine vertical structure, spatial resolution, and uncertainty associated with the tomographic mapping of the internal tide.
