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 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.

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.
