Intermission: Surfing Neon Waves

Posted by Jillian Anthony

In San Diego, a red tide means a nocturnal light show, as you'll see in this video. When surfers disturb the algae-filled ocean waters, the organisms begin to glow, and the sea bursts with blues, greens, and purples. The phenomenon, called bioluminescence, occurs when a plethora of phytoplankton invade coastal areas, literally turning the sea a reddish hue that's visible during the day. It can make shellfish dangerous to eat, but at night, it's like a night light sent from King Triton himself.
