Turkey launches disaster management campaign to save Sea of Marmara from ‘sea snot’
- The thick layer of organic matter, known as marine mucilage, has spread through the sea south of Istanbul
- Environment Minister Murat Kurum said sea surface-cleaning and barrier-laying boats were working to prevent the spread of the ‘sea snot’

Turkey vowed to save the Sea of Marmara on Tuesday by launching a disaster management programme meant to clean up a slimy “sea snot” outbreak threatening marine life and the fishing industry.
The thick layer of organic matter, known as marine mucilage, has spread through the sea south of Istanbul covering harbours, shorelines and swathes of the surface. Some has sunk below the waves, suffocating seabed life.
Environment Minister Murat Kurum said 25 sea surface-cleaning and barrier-laying boats, as well as 18 other vessels, were working to prevent the spread of the mucilage. Illegal fishing and “ghost” nets would be halted and Turkey would declare Marmara a protected area by the end of 2021, he said.
“We are starting our cleaning efforts both on land and at sea at 15 points today,” Kurum said. “We are determined to save the Marmara and we will save it.”
Some 1,000 workers would bring the waste to shore and truck it to municipal facilities, he said.
Scientists say climate change and pollution have contributed to the proliferation of the substance, which contains a wide variety of microorganisms and can flourish when nutrient-rich sewage flows into seawater.
