The Black Sea is connected to the Mediterranean Sea through a series of waterways collectively known as the Turkish Straits. This passage consists of the following, in order from the Black Sea to the Mediterranean:

  • The Bosporus: A narrow strait that connects the Black Sea to the Sea of Marmara.12
  • The Sea of Marmara: An inland sea located between the two straits.13
  • The Dardanelles: A strait that connects the Sea of Marmara to the Aegean Sea, which is an arm of the Mediterranean Sea.134
