Russia – October 2nd, 2012

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.

Europe – September 3rd, 2012

Smoke from fires in the Balkans blows over the high ridges of the Carpathian Mountains (left) in Romania and over the Ukraine. Visible in the lower right quadrant is the Black Sea, with the Danube Delta visible as a green triangular area on the Romania-Ukraine border.

Sediments and Phytoplankton in Caspian and Black Seas

Caspian Sea- July 25th, 2012

The bright colors in the northern part of the Caspian Sea are due partly to sediments from rivers such as the Volga, easily recognizable by its large, green delta, and the Ural, to the east of the former. They are also due in part to phytoplankton growth, which is likely encourages by the influx of nutrients from the two rivers. Upon opening the full image, the Black Sea  can be observed to the west. The phytoplankton bloom that has been flourishing there over the last month (click here for previous images) has now almost completely waned.

Phytoplankton Bloom in Black Sea Abating

Black Sea – July 23rd, 2012

The beautiful, intense blue phytoplankton bloom that has been brightening the waters of the Black Sea over the last several weeks (click here for previous images) has almost completely abated, and the sea’s waters return to their usual dark shade. The northwestern part of the sea shows almost none of the bloom, although sediments can be seen entering by several river mouths.

Phytoplankton Bloom in Black Sea Continues to Fade

Black Sea – July 19th, 2012

The waters of the Black Sea, earlier this month colored practically fluorescent hues of blue and green by an intense phytoplankton bloom (click here for previous images), appear to be returning to their usual dark blue shade, as the bloom fades. Phytoplankton blooms wane as the tiny organisms use up the nutrients in a body of water and can no longer reproduce at the same rapid rates as before.
