SUMMARY:One bubble\, two bubbles\, three bubbles\, four... the physics of 
 bubbles and how to eavesdrop on a breaking wave - Helen Czerski\, Departme
 nt of Oceanography\, University of Rhode Island
DTSTART:20090529T101500Z

CONTACT:Stephen Walley
DESCRIPTION:Breaking waves in the open ocean generate huge number of bubbl
 es\, and these bubbles have a significant influence on optics\, acoustics\
 , gas transfer and aerosol production in the upper ocean.   However\, meas
 uring the bubble population is challenging because the large bubbles fragm
 ent or escape to the atmosphere rapidly and the smallest ones are invisibl
 e to most optical and acoustical techniques.    I will discuss high-speed 
 photography experiments which demonstrate how bubble dynamics is linked to
  the sound that bubbles produce naturally\, and how these experiments will
  improve our ability to understand the upper ocean.
