An underwater acoustics experiment performed jointly by the APL at the University of Washington School of Oceanography and the Acoustical Oceanography Research Group at the IOS. In this experiment acoustic arrays are designed to record images of sea surface zone backscattering in order to distinguish between rough surface scattering and scattering from bubble distributions near and beneath the surface. The hypothesis being tested is whether the small void fraction bubble clouds are responsible for the observed increase over simple rough surface backscattering predictions at moderate to high wind speeds.
