UNITED NEWS INTERNATIONAL (UNI) — A bioluminescent phytoplankton bloom recently lit up the waves in Big Sur, California.

Photographer George Krieger captured the natural phenomenon .

In a Facebook post, Krieger described it as an “amazing spectacle.” He explained some of the images are frames stacked on top of each other.

The shots show the water under California’s Bixby Creek Bridge.

Steve Haddock, a bioluminescence expert at the Monterey Bay Aquarium, told KSBW that the phytoplanktons are probably dinoflagellates.

He said there has been an uptick in reports of bioluminescent waves since early last month and attributes it to calm water and a high nutrient content.

Phytoplankton give off blue light after they become disturbed by movements, such as waves or marine life swimming close by.

In addition to California, Florida and Taiwan are also known for having bioluminescent phytoplankton blooms off their coasts.
