Abstract:

The goal of this research is to increase our understanding of the impact of the ocean and seafloor environmental variability on deep-water long-range ocean acoustic propagation and to develop methodologies for including this in acoustic models. Experimental analysis is combined with model development to isolate specific physics improve our understanding. During the past few years the physics effects studied have been three dimensional propagation on global scale s, deep water ambient noise , under-ice scattering, bathymetric diffraction and the application of the ocean acoustic Parabolic Equation to infrasound.
