The ongoing collision between the Eurasian and African plates and westward escape of the Anatolian block along the North Anatolian Fault and East Anatolian Faults dictates the current tectonic regime, It is these geological mechanisms which, in the long term, have caused the periodic isolations of the Black Sea from the rest of the global ocean system.

Currently the Black Sea water level is relatively high, thus water is being exchanged with the Mediterranean.

The Turkish Straits connect the Black Sea with the Aegean Sea, and comprise the Bosphorus, the Sea of Marmara and the Dardanelles.

The Black Sea is also connected to the Sea of Azov by the Strait of Kerch. Due to these variations in the water level in the basin, the surrounding shelf and associated aprons have sometimes been land.

At certain critical water levels it is possible for connections with surrounding water bodies to become established.

The Black Sea has a positive water balance; that is, a net outflow of water 300 km (72 cu mi) per year through the Bosphorus and the Dardanelles into the Aegean Sea.

Mediterranean water flows into the Black Sea as part of a two-way hydrological exchange.Inflow from the Mediterranean has a higher salinity and density than the outflow, creating the classical estuarine circulation.This means that inflow of dense water from the Mediterranean occurs at the bottom of the basin while outflow of fresher Black Sea surface-water into the Marmara Sea occurs near the surface.The Black Sea outflow is cooler and less saline, and floats over the warm, more saline Mediterranean inflow – as a result of differences in density caused by differences in salinity – leading to a significant anoxic layer well below the surface waters.The Black Sea drains into the Mediterranean Sea, via the Aegean Sea and various straits, and is navigable to the Atlantic Ocean.including the countries of Austria, Belarus, Bosnia and Herzegovina, Bulgaria, Croatia, Georgia, Germany, Hungary, Moldova, Poland, Romania, Russia, Serbia, Slovakia, Slovenia, Turkey and Ukraine.
