Despite their prevalence in shallow water environments, sand sediments remain poorly understood acoustic media, with one of the largest gaps in our understanding lying at the high 100 kHz frequencies. This lack of understanding has important consequences for many practical applications including the remote sensing of sediment properties. The goal of the proposed research was 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. In order to perform the datamodel comparisons, extensive environmental characterization was also to be performed in the pond and at-sea.
