What is Sea Snot?

Sea Snot’: Turkey:

Turkey’s Sea of Marmara, which connects the Black Sea to the Aegean Sea, has witnessed the largest outbreak of ‘sea snot’.

  • A ‘sea snot’ outbreak was first recorded in the country in 2007.

Sea Snot and its Formation:

  • It is marine mucilage that is formed when algae are overloaded with nutrients as a result of water pollution combined with the effects of climate change.
  • The nutrient overload occurs when algae feast on warm weather caused by global warming.
  • It looks like a viscous, brown and foamy substance.

Concerns:

  • Threat to the Marine Ecosystem:
    • It has caused mass deaths among the fish population, and also killed other aquatic organisms such as corals and sponges.
    • It is now covering the surface of the sea and has also spread to 80-100 feet below the surface which eventually can collapse to the bottom and cover the sea floor.
  • Livelihoods of Fishermen Affected:
    • As the sludge is getting collected in their nets, making them so heavy that they break or get lost.
    • Moreover, the mucilage coating the strings makes the nets visible to fish and keeps them away.
  • Water-borne Diseases:
    • It can cause an outbreak of water-borne diseases such as cholera in cities like Istanbul.
