The Bosphorus
It is the Sea of Marmara
The Turks live on land, not the water. Turkey has shores on several major bodies of water, though, including the Black Sea, Sea of Marmara, Aegean Sea, and the Mediterranean Sea, along with a plethora of straits, rivers, lakes, and streams.
The Bosphorus Strait connects Europe and Asia, as well as the Black Sea and the Sea of Marmara. It is an important waterway located in Istanbul, Turkey, and facilitates maritime trade and transportation between the two continents.

The Strait of Bosporous (sp?). The Golden horn
The Black Sea is not located in and ocean, it is a body of saline water located in a largely continental area (the Eurasian Continent) and only connected to the Mediterranean via the Sea of Marmara and the Bosporus canal near Istanbul Turkey.
The Meredian Sea is not a recognized body of water; it may be a typographical error. However, if you meant the Mediterranean Sea, it is connected to the Black Sea through the Bosporus Strait, which links the Sea of Marmara to the Black Sea. The Dardanelles Strait further connects the Sea of Marmara to the Aegean Sea, ultimately linking the Mediterranean Sea to the Black Sea. This connection allows for the exchange of marine species and influences the climate and ecosystems of the region.
The southern and western shores of Turkey are on the Mediterranean Sea. More precisely, the western coast is on a body of water of the Mediterranean which is called Aegean Sea, and which separates Turkey and Greece. The northern coast in on the Black Sea.
The Black Sea, the Marmara Sea and the Aegean Sea are all between Turkey and mainland Europe.
