Abstract
The bottom sediments of many coastal areas are contaminated by a truly awesome witches brew of ingredients (PCB’s, heavy metals, radioactive wastes, to name a few). The eventual fate of these contaminants is intimately tied in with the processes of coastal sediment transport. In recent years, acoustical remote sensing has become a powerful tool in measuring the process involved in coastal and deep sea sediment transport. In this talk, acoustical measurements made as part of a major experiment to understand the processes governing transport on the continental shelves, the ‘‘Sediment Transport on Shelves and Slopes’’ (STRESS) experiments will be discussed. Of particular interest here are the acoustical images of the near-bottom boundary layer, and their implications for sediment transport modeling. [Work supported by ONR.]
