Understanding and utilizing waveguide invariant range-frequency striations in ocean acoustic waveguides
(Massachusetts Institute of Technology, 2011)
Much of the recent research in ocean acoustics has focused on developing methods to exploit the effects that the sea surface and seafloor have on acoustic propagation. Many of those methods require detailed knowledge of ...
Three-dimensional acoustic propagation through shallow water internal, surface gravity and bottom sediment waves
(Massachusetts Institute of Technology, 2011)
This thesis describes the physics of fully three-dimensional low frequency acoustic interaction with internal waves, bottom sediment waves and surface swell waves that are often observed in shallow waters and on continental ...
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 ...
