High-Frequency Sound Interaction in Ocean Sediments High-Frequency Sound Interaction A 5-year ONR Departmental Research Initiative (DRI) on the interaction of high-frequency sound with the seafloor began in October 1997. The DRI addresses high-frequency sound penetration into, propagation within, and scattering from the shallow-water seafloor at a basic research (6.1) level. This overview summarizes the acoustics issues associated with the DRI, outlines the environmental characterization required to address the acoustic issues in a shallow-water experiment, and concludes with a brief description of some aspects of the first experiment. Program descriptions for investigators associated with the DRI follow in separate sections.
