Sea of Azov Lined with Golden Sediments, Black Sea Bright Blue from Phytoplankton – June 3rd, 201245.1N 36.2E
While the Sea of Azov (above) is lined with golden sediments that gradually fade to green and then disappear into the deep, dark blue waters towards the sea’s center, the Black Sea glows an intense, light, milky blue. This coloring is due to a phytoplankton bloom in the sea. The swirls are due to currents, while the differences in color are usually due to different species of phytoplankton. Over the years, scientists have observed over 150 different types of phytoplankton in the Black Sea (click here for more images of phytoplankton blooms in the Black Sea).
