It is located between Eastern Europe and Western Asia, and shares borders with Georgia, Russia, Romania, Bulgaria, Romania and Turkey. Connected to the Mediterranean Sea through the Bosporus Strait, the Sea of Marmara, and the Dardanelles Strait, The Black Sea is a natural corridor for marine traffic between Europe and Asia.

The water's stratification as a result of its narrow vertical mixing and steep salinity gradient is what causes this state. Marine archaeologists will find a wealth of preserved shipwrecks and old artefacts on the seafloor due to the anoxic conditions that preserve organic materials. For thousands of years, the Black Sea has served as a crossroads for civilizations. Along the coast, Greek colonists built trading ports, and eventually it b
