The goal of this research is to acquire a quantitative understanding, leading to predictive models, of the broader aspects of linear and nonlinear sound scattering, transmission and coherency in oceanic sediments and bubbly mixtures pertinent to the shallow-water acoustics. Of particular interest is the delineation of different regimes of behavior as a function of frequency, bubble size distribution, flow characteristics and volume fraction, and sediment properties. In all cases, we focus on lower-frequency behavior for which the effective medium approximation is valid.
