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.

Here, the Black Sea (upper right) can be seen connecting to the Sea of Marmara (center), which in turn connects to the Aegean Sea (lower left).

The Bosphorus strait connects the Sea of Marmara to the Black Sea and the Dardanelles strait to the Aegean. The former also separates Istanbul into its Asian and European sides. The Sea has an area of 11,350 km² (280 km x 80 km) with the greatest depth reaching 1,370 m.

Turkey - February 11th, 2011

Various straits and seas can be observed in this image of Turkey. In the upper left corner is the Black Sea, connected to the Sea of Marmara (center) by the Bosphorus Strait. Visible on either side of the Bosphorus is the city of Istanbul.

To the west, the Sea of Marmara is connected to the Aegean Sea by the Dardanelles. The strait is 61 kilometres (38 mi) long but only 1.2 to 6 kilometres (0.75 to 4 mi) wide, averaging 55 metres (180 ft) deep with a maximum depth of 82 metres (300 ft). Water flows in both directions along the strait, from the Sea of Marmara to the Aegean via a surface current and in the opposite direction via an undercurrent.

The whitish surface of the city of Istanbul, Turkey, is divided in two by the Bosphorus Strait. Upon opening the full version of this orthorectified image, ships can be seen north of the strait, in the Black Sea, and to the south, in the Sea of Marmara. Another body of water, Lake Iznik, is visible in the lower right quadrant.

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 Bosporus and the Dardanelles owe their existence to the fault lines running through Turkey that led to the creation of the Black Sea. There is an earthquake fault line across the north of the country from west to east, which caused a major earthquake in 1999.

The Bosphorus Strait, connecting the Black Sea (above) to the Sea of Marmara (below) divides the city of Istanbul, Turkey, in two. The Sea of Marmara has an area of 11,350 km² (280km x 80km) with the greatest depth reaching 1,370 m.

In this orthorectified image, some of the large, indented bays of the sea are visible cutting into the Turkish terrain on either side of the Koroglu Mountains. These include the Gulf of Izmit, center right, whose waters appear light grey, and the Gulf of Gemlik, center bottom. The body of water visible inland between these two gulfs is Lake Iznik.
