Green Algae in Sea of Azov, Ukraine and Russia46.0N 36.0E
Some greenish sediment and phytoplankton growth can be observed in the Sea of Azov. The sea is largely affected by the inflow of numerous rivers, which bring sand, silt, and shells, forming numerous bays, limans, and narrow sandbanks called spits. Also, due to the river inflow, water in the sea has low salinity and high content of biological matter, such as green algae that affects the water colour. Abundant plankton results in unusually high fish productivity.
