This effect is produced by a protozoza named Noctiluca scintillans…By night, there is an increase in microscopic plankton called dynoflagellates, which glow in the dark when disturbed by currents or waves.
Bioluminescent Waves Explained
Bioluminescent dinoflagellates cause the water off of La Jolla Shores beach to glow a neon blue when disturbed by animals, humans, and crashing waves
Q & A:
> Is there any way to predict when the ocean will be bioluminescent?
> What bioluminescent animals live in fresh water, and why are they so rare?
> How does GFP (Green Fluorescent Protein) make the luminescence of the jellyfish Aequorea turn green instead of blue?
> Why is blue a ‘favored color’ in marine environments while it seems absent in terrestrial organisms?
