A combined ocean acoustics and physical oceanographic data assimilation approach for real-time compu
Abstract
Development of real-time acoustic modeling tools and a combined ocean acoustics (OA) and physical oceanographic (PO) data assimilati,on method are proposed for use in the upcoming New England Sea Mount Acoustics (NESMA) experiment. This work will build on and benef,it from analysis of OA and PO data from the prior 2021 New England Shelf Break Acoustics (NESBA) experiment. The main focus of this,project will be on improving real-time computational acoustics modeling capabilities for use in predicting experimental acoustic pro,pagation, and diagnosing mismatch between model prediction and in-situ data collection to identify acoustically significant environm,ental features. In order to achieve this goal, two types of ocean environment characterizations will be pursued. First, for high spe,ed reactive calculations at sea, a blending of observed ocean data will be supplemented by PO model output to continually provide a,contemporary estimate of ocean state for OA model diagnostics. Second, a coupling of OA sensitivity modeling with PO data assimilati,on is proposed for increasing the accuracy of ocean state predictions. Ultimately, both methods, as well as all developed improvemen,ts to the real-time OA modeling efforts will be deployed during the upcoming NESMA science cruises.
