Abstract : A 5-year Special Research Program (SRP) has been established at the Naval Research Laboratory that addresses the physical characterization and modeling of benthic boundary layer processes and the subsequent impact of these processes on the seafloor properties that affect mine countermeasure operations. This special project outlines the SRP scientific program and reviews the results of the four workshops convened to establish scientific priorities. Workshop participants agreed that sediment structure provides the common perspective: to quantitatively model relationships among sediment physical properties; to quantify the effects of environmental processes on sediment properties; and to model sediment behavior (acoustic, electrical, and mechanical). Hypotheses based on quantitative physical models that incorporate three-dimensional sediment structure will be tested by a series of field experiments at coastal locations where differing environmental processes dominate sediment structure. These experiments stress the role of sediment structure in determining high-frequency acoustic phenomena such as scattering, penetration, and propagation, as well as the physical relationships between remotely sensed acoustic properties and mechanical strength parameters. Acoustics, Sediments, Mines.
