Geography

Caspian Sea

The Caspian Sea is an endorreic ocean with no access to the sea, so it has no natural exit, except evaporation, and is located between Asia and Europe. It is the largest inland body of water in the world, with an area of 371,000 square kilometers and a maximum depth of about 980 meters and has common characteristics that belong to seas and lakes. It is often listed as the largest lake in the world, although it is not a freshwater lake.

What is the Caspian Ocean?

The Caspian Ocean is an endorheic lake of brackish water, which is completely surrounded by land and has no direct access to the sea or ocean, even so, it contains a certain degree of salinity, so it is catalogued as the smallest ocean in the world

The Caspian Sea is bordered by five countries, Iran, Russia, Azerbaijan, Turkmenistan and Kazakhstan. Three main rivers, the Volga, Ural and Terek, and numerous smaller rivers flow into its waters.

Four-fifths of the world’s sturgeon catch, which produce eggs that are processed into caviar, comes from the Caspian Sea. In recent years, desiccation of spawning grounds, pollution, river damming and overfishing have threatened the sturgeon population.

Location of the Caspian Sea

The Caspian Sea is located in the eastern part of the Caucasus Mountains, in a deep depression that exists between the continents of Europe and Asia, approximately between 27 and 28 meters below sea level.

Iran, Azerbaijan, Turkmenistan, Russia and Kazakhstan are the five countries that surround the sea and on its shores are a number of different cities such as Baku, Aktau and Majachkalá.

History of the Caspian Sea

According to historians and geographers it is considered that the sea is approximately 30 million years old. It became a lake with no access to the sea some 5.5 million years ago. Discoveries in the Huto cave near the town of Behshahr in Iran point to the existence of a human population in the area 75,000 years ago.

In the 1960s and 1970s, its water level dropped considerably, as many of its waters were used for irrigation and other activities. In 1980, a dam was built at the mouth of the Kara-Bogaz-Gol to control water loss. An aqueduct was built to recover the flow of water to the Kara-Bogaz-Gol.

In classical antiquity it was called the Hircanian Ocean and is also known as the Khazar Sea. In Persian antiquity, as well as in modern Iran, it is known as the Mazandaran Sea. In ancient Russia it was also known by a different name and was called the Khvalyn Sea name which was later changed to the Khvalis Sea.

Characteristics

The main characteristics of the Caspian Sea are as follows:

Economy

It is an important area in terms of energy resources and oil fields. The region contains between 17 and 44 billion barrels of oil and gas reserves of approximately 230 trillion cubic feet.

It is a popular destination for domestic tourists. In Iran, the Caspian coast offers sandy beaches, lush vegetation and spectacular natural scenery. There are several resorts, entertainment facilities and holiday homes. Winters with good weather and hot summers, as well as its accessibility also make the Caspian coast a favorite vacation spot for Russians.

Politics

Part of the struggle over the Caspian’s resources was not military but political, because different Western NGOs managed to get into two vital allies of Moscow and make a series of changes in pro-Russian regimes for new allies of the West in the post-Soviet space, through political advertisements and denunciations of fraud in parliamentary and presidential elections.

The policy is based on three major issues that seek to regulate the status of the Caspian Sea: access to mineral resources (oil and natural gas), access to fisheries and access to international waters (via the Volga River and the canals connecting to the Black Sea and the Baltic Sea).

In 2003, Russia, Kazakhstan and Azerbaijan reached an agreement on their sectors, covering 64 per cent of the Caspian Sea. There are no problems between Kazakhstan and Turkmenistan, but Turkmenistan is not actively involved in the agreement. Azerbaijan disagrees with Iran over the oil fields claimed by both states. There are similar tensions between Azerbaijan and Turkmenistan over the amount of oil pumped from a shared recognized field. The southern part of the sea remains contested.

Russia and Kazakhstan signed a treaty, according to which they divided the northern part of the Caspian Sea between them into two sectors along the middle line. Each sector is an exclusive zone of its state. Therefore, all resources, seabed and surface are unique to the particular state.

Why it is called the Caspian Sea

Its name comes from the word ” Caspian “. In Aramaic language of the word “Kspy” and the Greek of the word “Kaspioi“, name of the ancient people who lived in the southwest of the lake. The Greek geographer and historian Strabo made different notes on the Caspian territory in the Caucasian Albania that had taken this name in honor of the Caspian tribe. It is called sea because at the bottom of its waters is a layer of ocean type.

Which rivers flow into the Caspian Sea

The Caspian Sea has different tributaries, we can mainly mention the Volga River which in turn forms a wide delta, the Ural River and the Emba River that reach it from the north. Other tributaries, such as the Gorgan River and the Atrek River come from the east, and the Kura River from the west. The Caspian is connected to the Sea of Azov through the Manych Canal.

Let’s look at some of these rivers in more detail:

Fauna

The Caspian Sea has a large quantity of fish and the majority of the sturgeon is found there, from where the caviar is extracted. We find fish such as salmon, perch, herring and carp. In addition, you can find animals like the turtle and the seal. The Caspian seal, also called Caspian pose, is common in the Caspian, and is one of the few species of seal that live in inland waters.

In recent years there has been the problem of overfishing threatened to sturgeon so environmental groups have begun to fight for a ban on sturgeon fishing, despite this fight, the prices of sturgeon caviar are so high that fishermen bribe the authorities to avoid legislation.
