Investigation of Complex Range-Dependent Shallow Water Sound Transmission

Abstract

This Postdoctoral Fellowship (Jon M. Collis) had three main goals. The first was to quantify the water sediment interaction zone boundary condition for acoustical applications, using theory, numerical computation, experimental results, and constrained inversions. The second was to use range-dependent codes along with geoacoustic profiles based on geophysical properties to develop hypotheses suitable for testing with at-sea experiments in waveguides with sandy bottoms. The third was the conduct experiments with a near bottom sound source and array to quantify the characteristics of the interface wave field.
