Glowing blue ocean bioluminescence in Monterey, California
Glowing blue bioluminescence at the beach in Monterey, California! The "red tide" and its associated blue glow is caused by microscopic dinoflagellates (phytoplankton) called Lingulodinium polyedra, which emit the glow when disturbed (e.g., from ocean waves on the beach). August 14, 2020.
