Underwater Lightning Project

Uploaded by NatSciDemos on Nov 7, 2011
Many Pacific Island navigators have reported finding land by following mysterious streaks of light that extend between islands quite some distance away, and they report that it is not the ordinary kind of bioluminescence kicked up in the wakes of canoes. It is known, however, that fish can create streaks of light from pressure waves. We decided to see if we could create something that we thought looked like underwater lightning by using a trough of sea water containing dinoflagellates. Dinoflagellates are single celled organisms that photosynthesize during the day and have flagella attached. At night, when a pressure disturbance hits them, they emit light.
We pulled a segmented lure (Rapella is the manufacturer) through a tank filled with dinoflagellates in their night-time phase to see if it produced a result resembling 'underwater lightning'. You judge the results.

Visit the sea shore during a red tide event and experience this same phenomena in it's dramatic naturalness. Breakers lighting up the beach beautifully. Run barefoot backwards and see your own footprints linger for many seconds.

They photosynthesize during the day, storing up energy. They're single celled organisms that have a 'day' cycle where they store energy. In the night cycle, if disturbed they will emit light.

From the same thing it gets the energy to move, food.
