Bubble play. A better understanding of the bubbles formed when
waves break could improve climate models.  Peering Into the
Bubbling Surf  Most surfers have experienced the inside of a
wave--along with either the ecstasy of riding through the tube,
or the agony of being spun headlong under the brine. But neither
these wave motion experts nor their more classically trained
counterparts know exactly what happens as a wave turns white and
breaks. Now, physicists have described for the first time how
bubbles form and fragment during this crucial moment. Although
the finding won't keep surfers on their boards, it is an
essential step in understanding how the ocean absorbs greenhouse
gases.  To study the guts of a wave, two land-lubbing physicists
--Grant Deane and Dale Stokes of the Scripps Institution of
Oceanography in La Jolla, California--videotaped breakers in a
laboratory flume and in the open ocean. Their findings,
published in the 22 August issue of Nature, offer a narrative of
a crashing wave. As the crest
