A Slimy Calamity Is Creeping Across the Sea

Divers who have seen the phenomenon firsthand describe many types of underwater sea snot. There are the “stringers,” which most resemble the sticky goo that might actually come out of your nose. But there are also floating “clouds,” white and ethereal, so delicate that they break apart in your fingers. Then there are the tiny flakes of “marine snow,” which begin as drops of mucus and accumulate organic debris as they drift slowly, slowly down to the bottom of the sea.

Then there is whatever is happening off the coast of Turkey—a downright in the words of Turkish President Recep Tayyip Erdoǧan. The sea snot there has surfaced and turned monstrous, gelling, this foul mucus has blanketed the Sea of Marmara, which connects the Black Sea and the Aegean Sea in the Mediterranean. It’s smothering shellfish, clogging nets, and destroying the fishing industry.
