Abstract

The bottom of the ocean is composed of randomly inhomogeneous, anisotropic layers of sediments. A geoacoustic data set is constructed from previously measured geological experiments in shallow-water regions of the New Jersey Continental Shelf. This data set is used as input for a stochastic reflection model based on the Monte Carlo technique in order to study the effect of the random variations of the seafloor properties on the scattering and reflection of acoustic plane waves in a shallow ocean. It is found that the random inhomogeneities as well as the anisotropy of the subsurface are major causes of volume scattering and certain anomalies in the reflection coefficient.
