Why Does San Diego's Ocean Glow Blue?

Season 43 Episode 3 | 1m 53s

Just off San Diego's shore, single-celled algae called dinoflagellates start to reproduce and if disturbed, a chemical reaction within the cell creates a tiny spark of light. When the conditions are right, the algae multiply and the coastal waters glow blue.
