Ambient Noise (AN) and Ocean Surface Physics
Abstract
"The overall objective for the proposed work is to improve operational predictions andapplications of ambient noise in the ocean by using state-of-the-art environmental models andobservations that capture the relevant surface physics, especially surface wave breaking. Thespecific objectives are to1. Apply recent advances in wave breaking measurements (bubbles and dissipation) to ambientnoise prediction,2. Participate in a new field experiment and contribute spatially distributed measurements ofambient generation by breaking surface waves, and3. Relate ambient noise to output from wave forecast models and coupled atmospheric-oceanmodels.To resolve the spatial heterogeniety in ocean surface forcing, a new dataset will be collected aspart of a larger field experiment with a new billboard array led by Laurie Fialkowski (NavalResearch Laboratory, Acoustics Division) in June 2022. Proposed measurements will useSWIFT drifters, developed under prior ONR support, to quantify the spatial and temporalpatterns of wave breaking, rainfall, and ambient noise. These measurements will be combinedwith forecast models to improve ambient noise predictions."
