JOINT ACOUSTICS/OCEANOGRAPHY EXPERIMENT ON THE WASHINGTON SHELF FOR MID-FREQUENCY SONAR APPLICATIONS

Abstract

The aim of this proposal is to combine oceanographic modeling, in situ oceanographic measurements, and in situ acoustic measurements to improve mid-frequency sound propagation on the continental shelf. The site of the field work will be conducted off the Washington coast in 2022. This proposal, which focuses on acoustics, is closely linked to two other proposals, one from APL-UW oceanography,the other from NRL, both focus on ocean modeling and measurements. The overall goal is to identify, quantify, and model submesoscale ocean processes and their impacts on mid-frequency propagation. The dominant ocean phenomena to be studied are fresh water mixingwith deep water upwelling which results in acoustic ducts. The impact of such ducts on variability of mid-frequency sound will be studied quantitatively.
