Blue Tide phenomenon observed in Maharashtra

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

Key takeaways

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

  • Bioluminescence is the property of a living organism to produce and emit light.
  • Animals, plants, fungi and bacteria show bioluminescence.
  • A remarkable diversity of marine animals and microbes are able to produce their own light.

  • Luminescence is generally higher in deep-living and planktonic organisms than in shallow species.
