ONR Postdoctoral Fellowship: Investigation of Complex Range-Dependent Shallow Water Sound Transmission

Abstract

This Postdoctoral Fellowship has three main goals. The first is to quantify the water sediment interaction zone boundary condition for acoustical applications, using theory, numerical computation, experimental results, and constrained inversions. The second is to use range-dependent normal mode and parabolic equation 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 is to conduct experiments with a near bottom sound source and array to quantify the characteristics of the evanescent, compressional, shear, and slow wave fields.
