Leighton, T.G., Simpson, M.D., Meers, S.D., White, P.R., Heald, G.J., Dumbrell, H.A., Clarke, J.W.L., Birkin, P.R. and Watson, Y. (2000) Surf-zone bubble detection using multiple techniques: the Worbarrow Bay experiment. Journal of the Acoustical Society of America, 108 (5), 2493.

Abstract

This paper describes a multisensor experiment to characterize the bubble population and its effects in the surf zone. Active bubble detectors (combination-frequency sensors, and the inversion of sound speed and attenuation) provided estimations of the bubble-size distribution, and allowed better interpretation of more novel sensors. These include acoustoelectrochemical sensors, and estimations of the bubble population from the ring-up time associated with the insonification of the population, and from the ambient noise (attention being paid to how the ringing population so determined differs from the full population measured by active techniques).
