Ambient Noise Measurements and Inversions in Coastal and Continental Shelf Waters

Abstract

The long term objectives are to: (1) study the role of wave-induced bubble plumes in ambient noise generation, and (2) characterize acoustic scattering from high void fraction bubble plumes at the sea surface. The origin of the numbers and sizes of bubbles produced within whitecaps, the f-5/3 dependence of wave-induced noise power on frequency, and the relationship between noise level and surface wave energy dissipation are of particular interest.
