NASA: Black Sea - Novorossiysk. Anapa area - Plankton Bloom - 01.05.13

The Black Sea, a large inland water body that connects eastern Europe and Asia Minor, frequently hosts widespread blooms of phytoplankton
during the spring and summer seasons. This astronaut photograph, taken
from the International Space Station, highlights a recent bloom in the
Black Sea’s eastern half.
The phytoplankton are visible as blue to turquoise streams and swirls, carried by currents along the coastline and further out towards the middle of the sea. The urban areas of Anapa and Novorossiysk—the largest Russian seaport on the Black Sea—are visible along the northern shoreline as grey-white regions nestled between the sea and uplands dotted with limestone quarries. (Note that north is to the upper left in this image.)
Phytoplankton occupy the base of most aquatic food chains and therefore serve as the primary producers in these ecosystems, despite being microscopic in size. The term “phytoplankton” includes a number of organisms—cyanobacteria, diatoms, dinoflagellates, algae, and coccolithophores—that feed larger creatures such as fish and shrimp.
The Black Sea receives contributions of freshwater from several river systems, including the Danube, Dnieper, Dniester, and Don, but it is also connected to the saline Mediterranean and Marmara Seas. These same river systems transport nutrient-filled urban and agricultural runoff to the Black Sea; the nutrients are consumed by phytoplankton and lead to blooms.

Astronaut photograph ISS035-E-40035
was acquired on May 9, 2013, with a Nikon D3S digital camera using a 50
millimeter lens, and is provided by the ISS Crew Earth Observations
experiment and Image Science & Analysis Laboratory, Johnson Space
Center. The image was taken by the Expedition 35 crew. It has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab
to help astronauts take pictures of Earth that will be of the greatest
value to scientists and the public, and to make those images freely
available on the Internet. Additional images taken by astronauts and
cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Caption by William L. Stefanov, Jacobs/JETS at NASA-JSC.
