Red Tide at midnight

    Newer Older

    Bioluminescent dinoflagellates (Lingulodinium polyedrum) lighting a breaking wave at midnight. The blue light is a result of a luciferase enzyme (like firefly luciferase, but the enzyme in L. polyedrum shares no similarity with that of the firefly enzyme). Under the right conditions, the dinoflagellates become so numerous that the water takes on a muddy reddish color (hence the name "Red Tide"). The bioluminescence is only visible at night. The photo was taken 6/26/2005 with a Canon Rebel XT - 6s, f5.6, ISO 1600, 85mm (135mm equiv).

      Great shot! This was what I saw but couldn't capture with my camera. :) How amazing it was. I didn't think it would happen again so soon.

      This is the single finest example of the phenomenon of red tide bioluminescence captured on film that I am aware of. would you consider possibly changing its copyright to a CC "some rights reserved" designation such that it may be used on the wikipedia ?

      Thanks for asking. I've changed the image license to NonCommerical, NoDerivs. Hopefully that is okay for posting on the Wiki. I also added a second photo from the same night that shows a broad section of the beach and the stars. The photo was also taken with my Canon Rebel XT with the noise reduction function.

      Perhaps it has more to do with the water temperature. Where in Mexico did you see it? Do you have any idea what the water temperature was? I'll keep my eyes out for it here in Carlsbad CA, but I'm guessing that we won't see it again until the water is warmer (I took the wave picture at the end of June). I have not seen it since 2005, although I don't frequently drive along the coast at night...

      These are gorgeous! I'm going to show them to my biology students who will be learning about dinoflagellates this week.
