Bubble measurements were performed in a wind-water simulating facility with a laser-based single-particle scattering technique. To avoid the usual ambiguity in this technique about the cross section, an original numerical processing of the scattered intensities, taking advantage of the low particle (bubble) velocities, was used. This treatment allowed one to directly obtain concentration probability densities. Moreover, other information, such as the crossing frequency, arrival time interval, or estimated speed distribution, that provides additional insight into the bubble distribution processes is available. The investigations were carried out in the immediate vicinity of breaking waves generated either by the wind flow or by the cumulative effects of the wind and a wavemaker. High bubble concentrations, no peaked distributionsm and important modifications of these distributions with wave ages were observed. The bubble speed and additional arrival time information allowed further notice of high fluid-estimated velocities and characterization of bubble clusters in the vicinity of breaking waves. Distinctive features of previous approaches, or models about wave-breaking bubbles, may be found in this investigation.
