Description:Black Sea is the most voluminous anoxic basin and an ecosystem with unique particularities. One of the most intriguing facts about the Black Sea is its depletion of oxygen and its layers of water that almost never intermix.
The thin upper layer of marine water (up to 150-200m) supports the unique biological life in the Black Sea ecosystem. The deeper and more dense water layers are saturated with hydrogen sulfide.
The Black Sea is also unique because it is semi-closed and its catchment area is five times bigger than the sea surface itself.
The most important environmental constraints of the Black Sea, still considered “the most seriously degraded sea on our planet” (GEF, 1992), consist of ecosystem changes.
