Black Sea – May 9th, 2013
Swirls of light blue and green phytoplankton and sediment are visible near the shores of the Black Sea. The Black Sea drainage basin encompasses almost one third of Europe, and each year an estimated 350 km3 of runoff enters the Black Sea, bringing substantial sediment and into the semi-enclosed waters. With these sediments come nutrients and fertilizers, which encourage the growth of phytoplankton.
