Results of a Study of the Ocean Bottom Interaction of Underwater Sound.

Abstract

This report describes the research of the second year of an on-going program to investigate the broad spectrum of problems associated with the interaction of underwater sound with the ocean bottom. The emphasis is on quantifying the nature of the acoustic bottom interaction problem, isolating key parameters, and developing useful minimal descriptions. This report considers in detail questions in the areas of the sensitivity of bottom reflection loss to variations in subbottom parameters, the sensitivity of propagation loss to changes in bottom reflection loss, and problem associated with range changing bathymetry. Additional topics considered include a review of acoustic methods for obtaining bottom sediment sound velocities, as well as various modeling problems. (Author)
