What happened to the Aral Sea and what caused it?
The ecosystem of the Aral Sea was destroyed mainly as a result of the increased salinity as well as the testing of weapons and other fertilizer run offs. The salinity of the water in the Aral sea was around 376 g/l by 1990 compared to the 35 g/l salinity of ordinary seawater.
Why is Aral Sea not a lake?
Sandwiched between Kazakhstan and Uzbekistan, the Aral Sea is actually a lake, albeit a salty, terminal one. It is salty because evaporation of water from the lake surface is greater than the amount of water being replenishing through rivers flowing in. It is terminal because there is no outflowing river.
Is the Aral Sea saltwater or freshwater?
The Aral Sea is actually not a sea at all. It is an immense lake, a body of fresh water, although that particular description of its contents might now be more a figure of speech than practical fact. In the last 30 years, more than 60 percent of the lake has disappeared.
Who destroyed the Aral Sea?
In October 1990 Western scientists confirmed the virtual disappearance of the Aral Sea in Soviet Central Asia, formerly the fourth largest inland sea in the world. The loss of sea water was the result of 60 years of intensive agriculture and pollution by the Soviet authorities.
What killed the Aral Sea?
By the 1950s, the Aral Sea was shrinking rapidly. A Soviet program to gain agricultural independence accelerated the water diversion, to the point that flow into the Sea declined eleven fold. Evaporation meant the remaining water had high salinity, effectively killing the once-thriving fishery.
Is Aral Sea recovering?
Today, the North Aral Sea in Kazakhstan has been revived, with water and economy returning to Aralsk.
How old is the Aral Sea?
The Aral Sea depression was formed toward the end of the Neogene Period (which lasted from about 23 to 2.6 million years ago ). Sometime during that process the hollow was partially filled with water—a portion of which came from the Syr Darya.
Is there a dark sea?
The Black Sea, also known as the Euxine Sea, is one of the major water bodies and a famous inland sea of the world. This marginal sea of the Atlantic Ocean, located between Eastern Europe and Western Asia, has become legendary for a long period of time.
How did humans change Aral Sea?
The Aral Sea was once the world’s fourth-largest lake, but an irrigation project drained nearly all the water. The consequences include the loss of a fishing industry, salt-laden dust affecting crops and human health, and an altered climate.
How deep is the Aral Sea?
Two dozen species thrived in its waters, including caviar-rich sturgeon, pike perch, and silver carp, known locally as fat tongue. The sea spread over more than 26,000 square miles, and ships could travel 250 miles from the northern port of Aralsk, in Kazakhstan, to the southern harbor of Muynak in Uzbekistan.
How much of the Aral Sea is left?
With no other major source of water, the Aral Sea has been evaporating and shrinking ever since. After 50 years, the lake’s area is 25 percent of its original size and it holds just 10 percent of its original volume of water.
