Waves, Bubbles, Noise and Underwater Communications

Abstract

There are 3 long-terms goals. The first is to measure and model the effects of near-surface bubbles on the generation, scattering and attenuation of sound during breaking wave conditions. Ultimately, the goal is to develop predictive algorithms for surface scattering conditions from measurements of the wind-generated ambient noise field. The second long-term goal is to measure, model and exploit focused acoustic arrivals that occur on short length scales beneath sea swell and study their impact on underwater communications systems in littoral and near-shore regions. The third long-term goal, to understand the physical mechanisms responsible for the Knudsen spectrum for wind-driven underwater ambient noise, has been achieved.
