Summary Underwater acoustics is a primary interest of the US Navy. To expand the understanding of the acoustically important oceanic processes, leading to improved acoustic propagation predictions, the collaborators will conduct an integrated ocean fluid physics and acoustics study with the goal of creating a broadly applicable and portable continental shelf-area acoustic prediction capability that includes the effects of internal and surface gravity waves as well as effects of the more-commonly handled subtidal-frequency large-scale processes. The research will (1) evaluate the ability of the models to fully capture the physics and the features that develop, (2) analyze the flow fields and waves that develop in two outer-shelf regimes, in idealized and realistic conditions, (3) analyze the acoustic propagation, and (4) compare the critical wave and acoustic effects with the ONR Shallow Water 2006 (SW06) data set, lab experimental data, and field data from other regions.
