Sea of Marmara: general information

Sea of Marmara is the Mediterranean Sea of the Atlantic Ocean, located between the European and Asia Minor parts of Turkey. In the northeast it is connected by the Bosphorus Strait with the Black Sea, in the southwest - by the Dardanelles Strait with the Aegean Sea. The shores are predominantly mountainous, in the south and east they are strongly dissected (the bays of Izmit, Gemlik, etc.). The largest islands are Marmara, Prinsevy; there are underwater reefs off the northern coast. Small rivers Granik, Susurluk and others flow into the sea (almost all - from the Asian coast). The sea does not freeze; in winter the surface water temperature is 9 ° C, in summer up to 29 ° C. The hydrology of the sea is characterized by the exchange of waters of the Black and Aegean Seas through the straits. Salinity on the surface is up to 26 ‰, which is much higher than in the Black Sea, but much less than in the oceans. At the same time, the salinity of the bottom water is noticeably higher - up to 38 ‰, which is comparable to the salinity of the waters of the Mediterranean Sea.
