Sound Propagation through a Moderate Coastal Upwelling: Comparison of Modeling Prediction with Experimental Data.
Abstract
In a previous paper, modeling predictions were made for the effect of a coastal upwelling on sound propagation. To verify these results, a sound propagation experiment was conducted across a moderately developed upwelling located at the Sur Canyon off the coast of California. A 1-kHz projector was towed through a sonobuoy field which spanned the upwelling region. A supporting oceanographic survey was made to obtain environmental data input for multi-profile modeling predictions. The relative importance of oceanographic and topographic changes on sound propagation were determined. A follow-on experiment in a fully developed upwelling is planned.
