Abstract

The past decade has seen significant advances in our understanding of open-ocean bubble plumes, including scaling laws for whitecap properties [W. K. Melville and P. Matusov, Nature (London) 417, 58–63 (2002)] and the physics of bubble creation [Garrett et al., J. Phys. Oceanogr. 30, 2163–2171 (2000), and G. B. Deane and M. D. Stokes, Nature (London) 418, 839–844 (2002)]. Despite this progress, we do not yet have a complete understanding of the relationship between noise radiated by whitecaps and the bubble creation processes occurring within the wave crest. Understanding this relationship is important: it would allow bubble-mediated gas transfer rates to be estimated from wind speed, for example, and provide a model for the Knudsen spectrum of underwater ambient noise. An important piece of this puzzle is the dependence of bubble acoustic radiation strength on bubble radius. We will present estimates of the scaling laws for this relationship based on open-ocean measurements of whitecap noise and laboratory measurements of bubble creation rates in plunging breakers.
