In the early summer, the Black Sea belies its name. As currents swirl in from the Danube and the Dnieper, they bring in nutrients and cold water: a perfect environment for microscopic coccolithophores, tiny phytoplankton armored with reflective plates. When the sun reflects off these little beasts, the water they’ve colonized looks turquoise.
This star’s-eye view is preferable to the one from the ground—a big, azure expanse that, the Guardian reports, has made some residents of Istanbul nervous about pollution. There’s nothing to worry about, though: besides being harmless and colorful, the phytoplankton are providing tons of food for anchovies and other small fish. Not bad for such a tiny creature.
