Green and Blue Swirls of Phytoplankton in the Black Sea

44.0N 36.7E

June 1st, 2012 Category: Phytoplankton

Black Sea - May 31st, 2012

An intense phytoplankton bloom colors the waters of the Black Sea bright shades of blue and green (click here for more images of phytoplankton blooms in the Black Sea). The swirls of color indicate the movement of water currents. Closer to the coast, the colors appear more green, perhaps a due to the mix of sediment and organic matter washing out from rivers and streams. Visible in the upper part of the image is the Sea of Azov, connected to the Black Sea via the Strait of Kerch. Although green sediments can be seen lining the Sea of Azov’s southern shoreline, no phytoplankton bloom is present.

Black Sea - April 28th, 2012

This thumbnail image focuses on the Sea of Azov and northern portion of the Black Sea, although the latter is visible in its entirety in the full image. The Sea of Azov is linked by the narrow (about 4 km) Strait of Kerch to the Black Sea to the south and is bounded in the north by mainland Ukraine, in the east by Russia, and in the west by the Ukraine’s Crimean Peninsula.

The Don and Kuban are the major rivers that flow into it. Visible to the northwest of the sea, in the upper left quadrant, is the Dnieper River. The large lake visible along the river is the Kakhovka Reservoir, covering a total surface area of 2,155 square kilometres in the territories of the Kherson, Zaporizhia, and the Dnipropetrovsk Oblasts of Ukraine.

Black Sea, from the Danube Delta to the Shores of Georgia – April 16th, 2012

Black Sea - March 18th, 2012

This image shows the entirety of the Black Sea, located in an elliptical depression which lies between Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. Visible on the western shores of the immense lake is the delta of the Danube River; sediments can be seen flowing from the delta into the sea. To the north, the Sea of Azov, northeast of the Crimean Peninsula and connected to the Black Sea via the Strait of Kerch, is partially covered in ice. The eastern part of the sea, near Georgia, is partially obscured by clouds.

Ukraine - November 25th, 2011

Crimea, is a sub-national unit, an autonomous republic, of Ukraine. It is located on the northern coast of the Black Sea (blue, below) and on the western coast of the Sea of Azov (green, upper right), on the Crimean Peninsula, bordering Kherson Oblast from the North. Crimea’s total land area is 26,100 km2 (10,077 sq mi).

Crimea is connected to the mainland by the 5–7 kilometres (3.1–4.3 mi) wide Isthmus of Perekop. However, it is almost cut off from the mainland by the Sivash Sea, actually a large system of shallow, silty lagoons. Here, the lagoons show varied, bright colors, ranging from lime green to electric blue to pink.

At the eastern tip of Crimea is the Kerch Peninsula, which is directly opposite the Taman Peninsula on the Russian mainland. Between the Kerch and Taman peninsulas, lies the 3–13 kilometres (1.9–8.1 mi) wide Strait of Kerch, which connects the waters of the Black Sea with the Sea of Azov.

The Crimean coastline is broken by several bays and harbors. The southeast coast is flanked at a distance of 8–12 kilometres (5.0–7.5 mi) from the sea by a parallel range of mountains, the Crimean Mountains. These mountains are backed by secondary parallel ranges. Seventy-five percent of the remaining area of Crimea consists of semiarid prairie lands, a southward continuation of the Pontic steppes, which slope gently to the northwest from the foot of the Crimean Mountains.

Black Sea - May 18th, 2011

The Black Sea occupies the majority of this image. It has an area of 436,400 km2 (168,500 sq mi), not including the Sea of Azov (the body of water northeast of the Crimean Peninsula that is lined with sediments and connected to the Black Sea by the Strait of Kerch).

The Black Sea forms in an east-west trending elliptical depression which lies between Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The longest east-west extent is about 1,175 km.

It is constrained by the Pontic Mountains to the south, the Caucasus Mountains (capped with snow by the right edge) to the east and features a wide shelf to the northwest. Visible on the western shores is the delta of the Danube River.
