Phytoplankton in the Black Sea

42.8N 38.2E

May 24th, 2013 Category: Phytoplankton

Black Sea – May 23rd, 2013

A phytoplankton bloom can be observed in the Black Sea, coloring its usually dark blue waters a paisley pattern of lighter blue. Putting together the biomass of all the phytoplankton in Black Sea in a usual day of August gives an astronomic number of about six million tons. This photosynthesizing mass (called standing crop) is growing (primary production), and, at the same time, disappearing due to grazing by zooplankton.

Sediments and Phytoplankton in the Black Sea – May 10th, 2013

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.


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.
