The goal of this work is to further develop and test models of volume scattering by utilizing the existing suite of instrumentation previously developed at APL- UW for the study of high-frequency acoustics. These models include perturbation models applied to scattering from the seafloor due to heterogeneities in the sediment properties, recently developed models by Dr. Ivakin 1, which model scattering from inclusions in the sediment such as shells and coarse grains, models which account for the transition layer observed during SAX99 which could have a strong effect on volume scattering at high frequencies, and perturbation theory for sound propagation through a varying poroelastic sediment.
