The glow is an indicator of a harmful algal bloom created by something called Noctiluca scintillans, nicknamed Sea Sparkle.
It looks like algae and can act like algae. But it’s not quite. It is a single-celled organism that technically can function as both animal and plant.
According to news.yahoo.com these type blooms are triggered by farm pollution that can be devastating to marine life and local fisheries, according to University of Georgia oceanographer Samantha Joye, who was shown Associated Press photos of the glowing water.
“Those pictures are magnificent. It’s just extremely unfortunate that the mysterious and majestic blue hue is created by a Noctiluca,” Joye wrote in an email Thursday.
