Temporal fluctuation of backscattered field due to bioturbatioon in marine sediments

Thumbnail
Abstract
Biological activity in marine sediments creates a time-varying, randomly fluctuating medium. A bio-diffusive model is proposed for predicting the temporal and spatial spectrum of sediment density fluctuations. Perturbation theory is used to model sediment volume scattering and the temporal correlation of the scattered field. These models are compared with field data recorded in a biologically active shallow water environment, and sediment blo-diffusion parameters are estimated.
