Hong Kong Seas Glow Blue from Bioluminescent Plankton Caused by Pollution

On January 22, the water lapping the shores of Hong Kong began to glow blue at night. This phenomenon, called “Sea Sparkle,” is generated by bioluminescent blooms of microscopic plankton called Noctiluca scintillans, which light up neon-blue when disturbed. Unfortunately, the blooms which cause this luminescence are triggered by pollution that can also devastate local fisheries and other marine life.

For the video slideshow featured here, the YouTube channel Story of Everything, which tells visual stories exclusively through images, used photos taken by Kin Cheung for an article on the Hong Kong blooms published on the website of The Atlantic.
