San Diego photographers are taking advantage of the serene and luminous glow of the surf this week.
Eerie neon blue waves have been seen against San Diego’s shore this week, creating some rare photo opportunities for locals. The phenomenon is created when a red tide, which is algae bloom filled with phytoplankton called “dinoflagellates,” rolls off waves onto or near the shoreline.
The organisms react with a bioluminescent chemical reaction when jostled as a way to warn predators, to lure prey, or communicate within their species. The blue glow can be created by a simple step in the water or crash of a wave.
