Still Waters Posted May 11, 2018 #1 Share Posted May 11, 2018 A dazzling neon blue tide in San Diego, California, has filled its beaches with electric aqua colours. By day the plankton turn the water red, but come nightfall they radiate a blue glow when the algae are disturbed by movement, such as waves crashing on to the shoreline. http://www.bbc.co.uk/news/video_and_audio/headlines/44076902/red-tide-electric-blue-waves-wash-california-shore Quote In pictures: California's neon blue tide http://www.bbc.co.uk/news/world-us-canada-44069368 4 Link to comment Share on other sites More sharing options...
