marine environments

History of Black Sea especially with respect to influences from the Danube river; relevant topics comprise e.g. pollution or the Black Sea as habitat for diadromous species migrating upstream the Danube (especially sturgeons, shads).

The Black Sea is the world’s most isolated sea. As its catchment area is six times larger than its surface area, and every year about 350 km³ of river water from an area covering almost a third of continental Europe flow into the Black Sea, the Sea is very vulnerable to pressures resulting from land-based human activities such as industry, agriculture and growing urban communities. These activities are potential sources of pollution, and if not properly managed can have a negative impact on the water quality and water uses.
