BLUE TIDE

Nov. 28, 2020

Over the last four days, visitors to beaches in Maharashtra have witnessed the spectacle of a fluorescent bluish glow when the waves hit the shoreline.

About:

  • The phenomenon is called ‘blue tide’, and appears when luminescent marine life make the sea appear a deep shade of blue.

  • The spectacle occurs when phytoplankton (microscopic marine plants), commonly known as dinoflagellates, produce light through chemical reactions in proteins. Waves disturb these unicellular microorganisms and make them release blue light.
