Abstract:

Our long-term goal is to develop accurate models for high-frequency penetration into, propagation within, and scattering from shallow water ocean sediments. Reaching this goal requires a better understanding of several fundamental issues important to high-frequency sediment acoustics. These issues include an understanding of the dominant scatterers versus frequency near the sediment surface, the appropriateness of stochastic descriptions of sediment inhomogeneities, the importance of single versus multiple scattering in sediments, the need for poroelastic sediment models, and an understanding of the physical and biological processes that determine sediment structure.
