Was the Aral Sea fresh water?

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.

Is the Aral Sea as big now as it was in 1960?

By 2010 the large Aral was 27 m and the small Aral 43 m above sea level. From 1960 to 1998, the sea’s surface area shrank by 60%, and its volume by 80%. In 1960, the Aral Sea had been the world’s fourth-largest lake with an area of 68,000 km2 (26,000 sq mi) and a volume of 1,100 km3 (260 cu mi).

Is the Caspian Sea freshwater?

Seas are typically salt water. While the Caspian Sea is not fresh water, its salty water is diluted by the inflow of fresh water, especially in the north. The question of whether it is a lake or a sea has political and economic ramifications, wrote Hanna Zimnitskaya in a 2011 Journal of Eurasian Studies article.

What lives in 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 can we stop the Aral Sea from shrinking?

There is no work under way to restore the southern region. It has always looked like a lost cause. So Aladin says it will keep shrinking and getting saltier until only brine shrimp are left. Using less water to irrigate crops could restore the entire Aral Sea, says Micklin.

Which sea has dried up?

In 2014, the eastern lobe of the South Aral Sea completely disappeared. Water levels in summer 2018 were not as low as they might have been, following a round of seasonal snowmelt in the spring. As the Aral Sea has dried up, fisheries and the communities that depended on them collapsed.

Is Aral Sea recovering?

The Aral Sea as a whole will never completely recover. The shoreline has radically changed, and the South Aral Sea remains almost completely desiccated. The North Aral Sea is recovering thanks to the $86 million Syr Darya Control and Northern Aral Sea project, funded by the Kazakh government and the World Bank.

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.

How are officials trying to fix the Aral Sea?

In the end, the economic infrastructure around the water system has been partially restored. Fourth, the countries in the region began discussions addressing trans-boundary water issues, improving water management, investing in water-saving technologies, and upgrading networks of canals, dams and reservoirs.

What happened at the Aral Sea?

The dried up sea bed produced dust storms laden with chemicals and pesticides from the intensive agriculture occurring along the two rivers. This in turn led to increased air and water pollution levels, and crop damage as much as 1,000 km away.

Who is to blame for the Aral Sea shrinking?

By establishing a program to promote agriculture and especially that of cotton, Soviet government led by Khrouchtchev in the 1950s deliberately deprived the Aral Sea of its two main sources of water income, which almost immediately led to less water arriving to the sea.

Why the Aral Sea is shrinking?

The Aral Sea began to quickly shrink because of the evaporation of its now unreplenished waters. By 1989 the Aral Sea had receded to form two separate parts, the “Greater Sea” in the south and the “Lesser Sea” in the north, each of which had a salinity almost triple that of the sea in the 1950s.

How deep is the Aral Sea?

42 m
