Why San Diego's tides are glowing blue


Surfers, kayakers and beach-combers in San Diego, California, were greeted by a bizarre and beautiful sight: the ocean waters emitting a bright blue glow as the waves crashed and the tide came in. The cause of this phenomenon is a tiny organism called Lingulodinium polyedrum. This type of algae blooms every few years in the waters on the California coast forming what is known as a red tide. While the algae gives the water a soupy red color during the day, nighttime is when the show begins. Everytime the algae is jostled by the movement of the tides or a boat moving through the water, it emits a bright blue bioluminescent glow. The breathtaking light show appeared earlier this week, and scientists aren't sure how long it will last. https://ift.tt/2I4DTHM http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com
