Why in News?

The largest Sea Snot outbreak is being witnessed in Turkey’s Marmara Sea, which connects the Black Sea to the Aegean Sea.

This outbreak of mucilage is believed to be one of the largest on record, till date, and has created havoc along the country’s coastline for months. It has suffocated the marine life, cloaked the harbours and clogged fishermen’s nets.

How is Sea Snot formed?

  • When algae are overloaded with nutrients as a result of water pollution and climate change, it begins to create a thick slimy layer on the surface of the water.
  • This layer is colloquially known as sea snot.
  • These algae feast and grow in warm and nutrient-rich water.

The major causes of Sea Snot include:

  • One of the biggest causes of this layer of snot is global warming and the increasing temperature of the water bodies
  • The climatic conditions and the severe variations in climate change is another cause of this.
  • The increased water pollution is another key factor resulting in the formation of sea snot
