Phytoplankton Still Blooming Intensely in Black Sea – June 26th, 201243.6N 31.6E
A beautiful blue phytoplankton bloom continues to flourish in the Black Sea (click here for previous images). Here, the massive bloom covers more of the southern half of the sea. Although the Black Sea is connected to Sea of Marmara (lower left) through the Bosphorus Strait, no phytoplankton is blooming the Sea of Marmara.
Phytoplankton is made up of protists, bacteria and algae that use nutrients delivered by rivers to conduct photosynthesis. The amount of runoff present in the water determines their numbers. The Black Sea primarily receives nutrients from the Danube, the Dnieper, the Dniester, and the Don rivers.
