For more than six months now, parts of the Sea of Marmara along Turkey’s coast have been covered in a thick layer of glop known as mucilage, or “sea snot.” Pollution, warmer temperatures, and other environmental factors appear to have resulted in a proliferation of phytoplankton, which are releasing an “overabundance of mucus.” Government workers have been trying to clean up some of the worst-hit areas as biologists and environmentalists have expressed alarm. Below, you’ll find a recent collection of sea-snot images; for the complete story, read “A Slimy Calamity Is Creeping Across the Sea” by our own Sarah Zhang.
