Abstract:

Passive acoustic remote sensing of the marine environment has been developed to the point that we are able to make quantitative measurements of precipitation and wind speed. These processes are an important component of the ocean surface environment. Accurate sustained long-term time series of these processes from a variety of locations and environments are required for climate studies, model development and validation of other measurement techniques. This research seeks to build on the existing understanding of the sound generation mechanisms for wind, wave breaking and precipitation to improve the geophysical interpretation of the ambient sound field in the ocean. In turn, given environmental weather conditions, predictive Naval ocean ambient noise models will be improved. The long-term goal of this research is to make passive acoustic remote sensing of the marine environment an accepted standard measurement technique.
