How dirty is Caspian Sea?

Environmental challenge The Caspian basin is also rich in oil and gas. The Sea’s marine environment suffers from an enormous burden of pollution from oil extraction and refining, offshore oil fields, and huge volumes of untreated sewage and industrial waste, introduced mainly by the Volga River.

Does the Caspian Sea have whales?

It is home to several unique species of marine fauna Most of these are protected species to prevent ecological damage. Through archaeological surveys, researchers have identified possible evidence of dolphins, porpoises, and whales in the Sea around 50,000 – 100,000 years ago.

What makes the Caspian Sea unique?

Yet the Caspian Sea has some unique features that make its identity problematic. It is an inland sea that can only be accessed through Russia’s Volga River and the canals connecting it to the Black Sea, the Baltic Sea and the Sea of Azov.

Which river flows into the Caspian Sea from the east?

A second affluent, the Ural River, flows in from the north, and the Kura River flows into the sea from the west. In the past, the Amu Darya (Oxus) of Central Asia in the east often changed course to empty into the Caspian through a now-desiccated riverbed called the Uzboy River, as did the Syr Darya farther north.

How did the Atlantic Ocean become an evaporite sink?

During warm and dry climatic periods, the landlocked sea almost dried up, depositing evaporitic sediments like halite that were covered by wind-blown deposits and were sealed off as an evaporite sink when cool, wet climates refilled the basin. (Comparable evaporite beds underlie the Mediterranean.)

What is the Caspian Sea Shipping Company of Azerbaijan?

The Caspian Sea Shipping Company of Azerbaijan, which acts as a liaison in the Transport Corridor Europe-Caucasus-Asia (TRACECA), simultaneously with the transportation of cargo and passengers in the Trans-Caspian direction, also performs work to fully ensure the processes of oil and gas production at sea.
