This cloud-free, Sea-viewing Wide Field-of-view Sensor (SeaWiFS) image of the Black Sea on June 9, 2003, reveals the colorful interplay of currents on the lake’s surface. The green crescent-shaped pattern in the northwestern corner of the Black Sea is due to the nutrient-rich, sediment-laden discharge of the Danube River stimulating biological activity. The brighter, more turquoise patterns on the lake to the south and east are probably blooms of another type of phytoplankton.
