Abstract:

The overall objective of this research is an understanding of the relationship between the physical structure of the sea floor and its acoustic response, so that knowledge of one can be used to make inferences about the other. Inferences in both directions are important the use of acoustics to investigate the physical and geophysical nature of the ocean floors is well known. Equally important is the ability to predict the acoustic response of the sea floor on the basis of its measurable physical properties.
