High Frequency Bottom Interaction Acoustics in the Atlantic Natural Laboratory

Abstract

The long term objectives of this project are as follows: (1) to develop a numerical technique capable of predicting the low frequency acoustic wave field scattered from geologically realistic models of the bottom/sub-bottom environment; (2) to isolate from the scattering models the physical mechanisms that dominate the long-range reverberation from the seafloor; and (3) to characterize the variations in bottom topography and sub-bottom properties that control the scattering of low frequency acoustic waves. Our goal is to identify the geological features on the seafloor that are responsible for strong, low grazing angle, monostatic, backscatter and to determine the physical scattering processes associated with these geological features.
