Subsurface acoustic ducts due to salinity gradients in coastal oceans: Oceanographic component of a joint acoustics experiment on the Washington shelf
Abstract
we propose one component of three interdependent and collaborative proposed research efforts that together have an overarching primary goal of significantly improving the prediction of SONAR signal excess and its uncertainty for a required duration (e.g., 72 hours) for a given operational area. The primary long-term goal of this specific component (APL-Ocean Physics) is to improve the predictive modeling of hydrographic features that control acoustic transmission of mid-range frequencies. This three year effort will parallel and integrate with the proposed APL-Acoustics and NRL work. APL-Ocean Physics, with decades of experience in coastal and submesoscale research and with proven, mission-appropriate observational tools, will lead the effort to determine the space and time scalesof the acoustic ducts and mechanisms responsible for duct formation and evolution. This effort will heavily leverage ongoing UW modeling efforts (LiveOcean), a host of ongoing observational assets on the Washington shelf, and existing ocean measurement tools.Approved for Public Release
