Emma Robertson asked the Naked Scientists:

Thank you, and we look forward to hearing your answer!

Aloha!

White surf is the same mechanism as froth on a beer: scattering of light from small droplets/small bubbles ... http://en.wikipedia.org/wiki/Mie_scattering

If the surf has a blue glow it's bio-luminescence ...
