Black Sea - June 25th, 2012

A beautiful blue phytoplankton bloom continues to flourish in the Black Sea (click here for previous images). Here, the massive bloom covers more of the southern half of the sea. Although the Black Sea is connected to Sea of Marmara (lower left) through the Bosphorus Strait, no phytoplankton is blooming the Sea of Marmara.

Phytoplankton is made up of protists, bacteria and algae that use nutrients delivered by rivers to conduct photosynthesis. The amount of runoff present in the water determines their numbers. The Black Sea primarily receives nutrients from the Danube, the Dnieper, the Dniester, and the Don rivers.

Black Sea - June 1st, 2012

The Black Sea appears various shades of bright blue due to an intense phytoplankton bloom. No bloom is visible in the Sea of Azov to the north (visible in full image), connected to the Black Sea by the Strait of Kerch, nor in the Mediterranean Sea to the south (bottom). However, the Sea of Marmara to the southwest (visible at center left), to which the Black Sea is connected by the Bosphorus, is showing signs of phytoplankton growth.

Turkey - January 2nd, 2012

This wide-swath ASAR image shows Turkey’s Marmara Region, so-named for the Sea of Marmara (below). The city of Istanbul can be observed near the image center, situated on both sides of the Bosphorus Strait; its most populated areas appear bright white. The strait connects the Sea of Marmara to the Black Sea (above). Much of the terrain of the Marmara Region consists of rolling plateau country well suited to agriculture.

The Bosphorus, Istanbul and Mountainous Terrain of Turkey – February 21st, 2012

Turkey - February 9th, 2012

This orthorectified wide-swath ASAR image shows the city of Istanbul, Turkey, straddling the Bosphorus. The world’s narrowest strait used for international navigation, it connects the Black Sea (top right) with the Sea of Marmara (top center).

Istanbul is the largest city of Turkey. The Istanbul metropolitan province (municipality) had 13.26 million people living in it as of December, 2010, which is 18% of Turkey’s population and the 3rd largest metropolitan area in Europe (including the Asian side of the city), after London and Moscow. The city is located in northwestern Turkey within the Marmara Region on a total area of 5,343 square kilometers (2,063 sq mi).

Turkey is divided into seven census regions: Marmara, Aegean, Black Sea, Central Anatolia, Eastern Anatolia, Southeastern Anatolia and the Mediterranean. The uneven north Anatolian terrain running along the Black Sea resembles a long, narrow belt. This region comprises approximately one-sixth of Turkey’s total land area. As a general trend, the inland Anatolian plateau becomes increasingly rugged as it progresses eastward. Turkey’s varied landscapes are the product of complex earth movements that have shaped the region over thousands of years and still manifest themselves in fairly frequent earthquakes and occasional volcanic eruptions. The Bosphorus and the Dardanelles owe their existence to the fault lines running through Turkey that led to the creation of the Black Sea.

Black Sea - July 14th, 2011

While the Aegean and Mediterranean Seas (below) are dotted with hundreds of Greek and Turkish islands, few are visible in the Black Sea (upper right).

The Black Sea is connected to the Sea of Marmara (center) via the Bosphorus Strait, with the city of Istanbul located on either side. The Sea of Marmara is then linked to the Aegean Sea through the Dardanelles.

In the upper left quadrant, the Danube River can be seen flowing along the border of Romania (above) and Bulgaria (below), to its delta on the shores of the Black Sea.
