Currently, we’re seeing a “red tide” algae bloom in San Diego. It’s a bit smelly and awful looking in the daytime (it smells of rotting trash and the ocean has a brownish color), but at night, when the breaking waves agitate the algae, they give off a somewhat eerie, blue glow, which is quite mesmerizing.
I previously photographed the red tide in San Diego in 2011. In 2020, it coincides with a full moon, which made for interesting photos, albeit not the ones I had envisioned – it was all in all too bright to see more details of the faint blue bioluminsescent glow.
