Structure of the answer:
Introduction:
Define what Blue-tide is.
Body:
The tide producing a fluorescent blue hue, popularly known as bioluminescence, recently made an appearance at Mumbai’s Juhu Beach and Devgad Beach in Sindhudurg, along Maharashtra’s coastline.
Bioluminescence has been an annual occurrence along the west coast since 2016, especially during the months of November and December. The spectacle occurs when phytoplankton (microscopic marine plants), commonly known as dinoflagellates, produce light through chemical reactions in proteins. A wave disturbs these unicellular microorganisms and makes them release blue light.
Explain its effects on marine ecosystem.
Conclusion:
Conclude with solutions to address the issue and suggest way forward.
