Explained: What is ‘Blue Tide’ Spotted Along Mumbai Coastline?

News: Bioluminescence or light-emitting tide made an appearance on Juhu beach in Mumbai.


  • What is Bioluminescence? It is the property of a living organism to produce and emit light.Animals, plants, fungi and bacteria show bioluminescence.
  • Why did the waves appear blue here? It appears when bioluminescent marine life makes the sea appear a deep shade of blue.The spectacle occurs when phytoplankton(microscopic marine plants) produce light through chemical reactions in proteins.Waves disturb these unicellular microorganisms and make them release blue light.
  • Are bioluminescent waves common in India? Bioluminescence has been an annual occurrence along the west coast since 2016.However, it is not common in India.
  • Is Bioluminescence harmful? While smaller blooms may be harmless, slow-moving larger blooms may have an impact on deep-sea fishing. According to marine experts, the phenomenon is an indicator of climate change.Factors such as the pattern of the wind and the temperature of the ocean also determine the occurrence of bioluminescent waves.

‘Sea sparkle’ has affected marine food chain:CMFRI

News: The bloom of Noctiluca Scintillans on Karnataka coast has displaced microscopic algae.


  • Noctiluca Scintillans commonly known as the sea sparkle is a free-living, marine-dwelling species of dinoflagellate that exhibits bioluminescence when disturbed (popularly known as mareel).
  • Affect on Marine Life: The toxic bloom of Noctiluca Scintillans was linked to massive fish and marine invertebrate kills and has displaced microscopic algae called diatoms which form the basis of the marine food chain.
  • Why is the species toxic? The species does not produce a toxin.But it was found to accumulate toxic levels of ammonia which is then excreted into the surrounding waters possibly acting as the killing agent in blooms.
