    The explanation that I remember about surf induced bioluminescence was
    that the surf caused a rebounding pressure wave which micro organisms
    would react to by emitting photons. The direction of the flashes were
    toward the island which seems a bit counter intuitive. I can't recall
    where I read about this but I am guessing that National Geographic or
    NOAA published something on this subject.
