Capillary Wave Spectra from Sound Reverberation Measurements

Abstract

There is a unique relationship between sound wave scattering from a rough surface and its elevation spectrum. This relationship allows the use of available underwater sound reverberation measurements in the wave number range 0.025 to 2.5 radians/cm (5 to 55 radians/sec) to be used to develop sea surface capillary wave spectra. As an aside, optically measured surface slope spectra are converted to elevation spectra and these suggest the possible variability of capillary wave height spectra as well as a "cut-off" wavelength due to viscous effects.
