Black Sea - July 12th, 2011

Visible in the center of this image is the Bosphorus, a strait in Turkey that forms part of the boundary between Europe and Asia. The world’s narrowest strait used for international navigation, it connects the Black Sea with the Sea of Marmara (which is connected by the Dardanelles to the Aegean Sea, and thereby to the Mediterranean Sea).

In the full image, the city of Istanbul can be observed on either side of the strait, despite the light cloud cover. Since it extends both on the European (Thrace) and on the Asian (Anatolia) sides of the Bosphorus, and is thereby the only metropolis in the world that is situated on two continents.

Turkey - July 15th, 2009

The city of Istanbul, Turkey, lines the Bosphorus Strait and the northern shores of the Sea of Marmara. Many ships can be seen moving through the strait and in the sea.

One large group is clustered off the coast of Istanbul west of the southern entrance to the strait, and another is further to the east near Tuzla, a headland on the coast at the eastern limit of Istanbul.

Also visible in the Sea of Marmara are the nine Princes’ Islands, located between the Bosphorus and Tuzla. Inland, the reservoir created by the Omerli Dam is visible east of the strait, and the large Lake Iznik touches the bottom edge of the orthorectified image. In between Lake Iznik and the Sea of Marmara above is the western part of the Koroglu Mountains.

Greece - April 10th, 2009

The Sea of Marmara, also known as the Sea of Marmora or the Marmara Sea, is the inland sea that connects the Black Sea to the Aegean Sea, thus separating Turkey’s Asian and European regions.

The Bosphorus Strait (upper left quadrant) connects it to the Black Sea and the Dardanelles strait to the Aegean. The city of Istanbul is visible along the shoreline of the sea and the Bosphorus Strait.

The sea has an area of 11,350 km² with the greatest depth reaching 1 370 m. Its salinity averages about 22 parts per thousand, which is slightly greater than that of the Black Sea but only about two-thirds that of most oceans.

However, the water is much more saline at the sea-bottom, averaging salinities of around 38 parts per thousand — similar to that of the Mediterranean Sea.

This high-density saline water, like that of the Black Sea itself, does not migrate to the surface. Water from the Granicus, Susurluk, Biga and Gonen Rivers also reduces the salinity of the sea, though with less influence than on the Black Sea. With little land in Thrace draining southward, almost all of these rivers flow from Anatolia.

Another body of water, Lake İznik, is visible in the lower right quadrant.  The lake is located in Turkey’s Bursa Province. It has an area of 290.00 km² and maximum depth of about 80 m.

The Bosphorus Strait, Turkey - January 27th, 2009

The Bosphorus Strait, Turkey - January 27th, 2009

The Bosphorus Strait divides Turkey into the regions of Thrace (closer to Europe) and Anatolia (closer to Asia), and connects the Black Sea to the North with the Sea of Marmara to the South.

The city of Istanbul can be easily spotted along the shores of the Sea of Marmara and the strait, as this densely populated area appears light brown, in comparison with the surrounding green vegetation and dark brown uneven terrain.

Lake Kuş (also called Lake Manyas) can be seen in the lower left hand corner. It is a shallow, nutrient-rich freshwater lake (average depth 3 m) fed by groundwater and four streams. The high presence of nutrients probably leads to greater algal growth and explains the vivid green color of the water.

Bosphorus Strait

Bosphorus Strait - December 11th, 2008

Bosphorus Strait - December 11th, 2008

The Bosphorus or Bosporus, also known as the Istanbul Strait, is visible here as the thick black line separating the two land masses. It is the strait that forms the boundary between the European part of Turkey (Thrace) and its Asian part (Anatolia).

The world’s narrowest strait used for international navigation, it connects the Black Sea (top) with the Sea of Marmara (bottom). Upon opening the full image, many ships and their wake trails are visible north of the strait.

The Bosphorus is approximately 30 km long, with a maximum width of 3,700 metres at the northern entrance, and a minimum width of 700 metres between Kandilli and Aşiyan; and 750 metres between Anadoluhisarı and Rumelihisarı. The depth varies from 36 to 124 metres in midstream.

The shores of the strait are heavily populated as the city of Istanbul (with a metropolitan area in excess of 11 million inhabitants) straddles it. Based on the white areas in the image, it appears that the area towards the Sea of Marmara is more populated than that towards the Black Sea.
