San Diego Bioluminesce 2020
At the end of March, San Diego and many other locations along Southern California's coast, experienced a red tides and bioluminesce event. The red tides that are present during the day and the bioluminesce that is present at night are caused by large gatherings of dinoflagellate, a microscopic organism. During the day, the organisms congregate near the water's surface which give way to the reddish-brown color of the water, hence the name "red tides." At night, the organisms give off the vivid blue bioluminesce when they become agitated by incoming waves, surfers or boats on the water, and other marine organisms. These red tides are unpredictable in terms of whether or not it will produce bioluminesce, when it will appear in an area, and how long it will last. To best view the nightly bioluminesce, if an event should appear nearby, one should visit coastal areas two hours after sunset. Currently, marine researchers are studying the dynamics of these red tides to understand them more fully.
