The effect of bubbles on sound propagation in the ocean has long been known. More recently, bubbles rising to the ocean surface have been related to salt nuclei in clouds. Yet due to the lack of suitable instrumentation little data are available on the concentration of bubbles in the ocean.

DeGrace, Carl W. (Monterey, California. Naval Postgraduate School, 2000-12);The presence of bubbles in a liquid decreases the average density, and thus decreases the buoyant force on a floating body. Competing with the decrease in buoyancy is an upward drag due to the bubble motion and entrained ...
Oscillating microbubbles created by water drops falling on fresh and salt water : amplitude, damping and the effects of temperature and salinity. Scofield, Christopher D. (Monterey, California. Naval Postgraduate School, 1992-06);Recent studies of underwater sound produced by raindrops have identified trapped bubbles as the principle sound source. Two mechanisms have been described, one for small drops (Type I) and one for large drops (Type II). ...
Arbogast, Steven M. (Monterey, California. Naval Postgraduate School, 2012-06);During an underwater explosion (UNDEX) event, a cavitation zone is created which alters the shockwave propagation parameters through this region. A cavitation zone is generally comprised of air bubbles whose material ...
