Recently, coastal waters around San Diego have been lit up by bioluminescent tides. At night, when the phytoplankton are agitated by waves or other movement in the water, they release a dazzling neon blue glow. Offshore moorings managed by the Southern California Coastal Ocean Observing System have been showing lots of Lingulodinium polyedra (L.poly) in varying levels of concentration. Red tide is due to aggregations of the dinoflagellate L.poly, a species well known for its bioluminescent displays. Each microscopic cell contains some “sunscreen,” giving it a reddish-brown color. On sunny days, the organisms swim toward the surface where they concentrate, resulting in the intensified coloration of the water—and the reason for the term "red tide." These photos were taken last Thursday and believed to be moving north, though not in as high of concentrations as seen in 2020. 🌊 More on red tides here: scripps.ucsd.edu/news/everything-you-wanted-know-about-red-tides All photos by Erik Jepsen/UC San Diego ...

Keep an eye out for bioluminescence along San Diego's coast! Our new state of the art Imaging FlowCytobots (IFCBs) at Del Mar Mooring and Scripps Institution of Oceanography Pier is detecting a lot of Lingulodinium polyedrum, a phytoplankton known to produce magnificent displays of bioluminescence at night, but be wary, L. poly is also known to produce yessotoxins.
