Effects of internal waves on low frequency, long range, acoustic propagation in the deep ocean
(Massachusetts Institute of Technology, 2007)
This thesis covers a comprehensive analysis of long-range, deep-ocean, low-frequency, sound propagation experimental results obtained from the North Pacific Ocean. The statistics of acoustic fields after propagation through ...
Geoacoustic inversion by mode amplitude perturbation
(Massachusetts Institute of Technology, 2007)
This thesis introduces an algorithm for inverting for the geoacoustic properties of the seafloor in shallow water. The input data required by the algorithm are estimates of the amplitudes of the normal modes excited by a ...
