Aralkum is the name given to the new desert that has appeared on the seabed once occupied by the Aral Sea.[1] It lies to the south and east of what remains of the Aral Sea in Uzbekistan and Kazakhstan.

History[edit]

While the level of the Aral Sea has fluctuated over its existence, the most recent level drop was caused by the former Soviet Union building massive irrigation projects in the region. The consequent severely reduced inflow subsequently caused the water level in the Aral Sea to drop. While the North Aral Sea is presently rising thanks to a dike, the South Aral Sea kept dropping, thus expanding the size of the desert, until 2010, when the South Aral Sea was partly reflooded. The water level of the South Aral Sea then began to drop again.

Geological makeup[edit]

The sands of the Aralkum and the dust which originates from it contain pollutants.[citation needed] The desert's location on a powerful east-west airstream has resulted in pesticides in the dust being found in the blood of penguins in Antarctica.[citation needed] Aral dust has also been found in the glaciers of Greenland, the forests of Norway, and the fields of Russia.
