Acoustic and optical measurements of bubble populations in the Atlantic ocean and the modeling of gas transfer through these bubble clouds
Acoustic and optical measurements of bubble populations in the Atlantic ocean and the modeling of gas transfer through these bubble clouds
Bubbles, formed by breaking waves, play an important role in the transfer of gases between the Earth's oceans and atmosphere and have been shown to increase the flux of gases during periods of heightened sea state. Having been formed, these bubble clouds evolve through the effects of buoyancy, gas exsolution and dissolution and the fragmentation and coalescence of bubbles. A number of experimenters have successfully measured sub-surface bubble clouds using a variety of acoustic and optical techniques. This paper presents data measured in the Atlantic Ocean, using an 11 metre spar buoy, between 16th June and 18th July 2007. An acoustic system measured the additional attenuation due to bubbles to infer the bubble size distribution whilst an optical system exploited the change in refraction caused by a bubble at the tip of an optical fibre probe. The measured bubble populations are then used as an input to a gas transfer model and the resulting fluxes and their significance are presented.

Abstract
Bubbles, formed by breaking waves, play an important role in the transfer of gases between the Earth's oceans and atmosphere and have been shown to increase the flux of gases during periods of heightened sea state. Having been formed, these bubble clouds evolve through the effects of buoyancy, gas exsolution and dissolution and the fragmentation and coalescence of bubbles. A number of experimenters have successfully measured sub-surface bubble clouds using a variety of acoustic and optical techniques. This paper presents data measured in the Atlantic Ocean, using an 11 metre spar buoy, between 16th June and 18th July 2007. An acoustic system measured the additional attenuation due to bubbles to infer the bubble size distribution whilst an optical system exploited the change in refraction caused by a bubble at the tip of an optical fibre probe. The measured bubble populations are then used as an input to a gas transfer model and the resulting fluxes and their significance are presented.
