  • Scientists have found that global warming is driving proliferation of Noctiluca algae (commonly known as sea tinkle), harmful algae in Arabian Sea responsible for glowing of Mumbai’s beaches in dark.
  • The study was jointly conducted by researchers from Indian National Centre for Ocean Information Services (INCOIS), a Ministry of Earth Sciences body US National Oceanic and Atmospheric Administration (NOAA).
  • The Noctiluca algae also called ‘sea sparkle’ is parasite which devours one of most important planktonic organisms at base of fish-food chain, namely diatoms.
  • It also excretes large amounts of ammonia, which causes massive fish mortality.
  • The intensifying global warming conditions will increase the proliferation of algae which in turn disrupt fish-food chain and cause decline of fisheries in the region.
