High-Frequency Sound Interaction in Ocean Sediments

Abstract

Our long-term goals are to develop accurate models for high-frequency scattering from, penetration into, and propagation within shallow water sediments, and to understand the conditions for which objects buried in sediments can be detected acoustically. Reaching these goals requires a better understanding of several fundamental issues pertinent to high-frequency sediment acoustics. These issues include an understanding of the dominant scatterers versus frequency near the sediment surface, the potential need for poroelastic sediment models, the appropriateness of stochastic descriptions of sediment heterogeneity, the importance of single versus multiple scattering in sediments, and an understanding of the physical and biological processes that determine sediment structure.
