Black Sea - May 31st, 2012

An intense phytoplankton bloom colors the waters of the Black Sea bright shades of blue and green (click¬†here¬†for more images of phytoplankton blooms in the Black Sea). The swirls of color indicate the movement of water currents. Closer to the coast, the colors appear more green, perhaps a due to the mix of sediment and organic matter washing out from rivers and streams. Visible in the upper part of the image is the Sea of Azov, connected to the Black Sea via the Strait of Kerch. Although green sediments can be seen lining the Sea of Azov’s southern shoreline, no phytoplankton bloom is present.
