The bloom was first detected in late March 2020 by an Imaging FlowCytobot (IFCB) at a mooring near Del Mar, California. The magical blue glow is thought to scare organisms that would disturb water trying to consume the phytoplankton, or perhaps attract the attention of something that will eat the phytoplankton predator. According to Latz, the organisms emit the light as a strategy to deter certain predators. The best time to see the glowing waves are a couple hours after sunset on a sunny day. Red tides can be caused by three types of microscopic, photosynthetic algae—dinoflagellates, cyanobacteria and diatoms.
