Death of Aral Sea, winds rise and spread the bottom salt on hundreds of kilometers around. Aral a once-large saltwater lake straddling the boundary between Kazakstan to the north and Uzbekistan to the south. The shallow Aral Sea was formerly the world's fourth largest body of inland water. It nestles in the climatically inhospitable heart of Central Asia, to the east of the Caspian Sea. The Aral Sea is of great interest and increasing concern to scientists because of the remarkable shrinkage of its area and volume in the second half of the 20th century. This change is due primarily to the diversion (for purposes of irrigation) of the riverine waters of the Syr Darya and Amu Darya, which discharge into the Aral Sea and are its main sources of inflowing water. The sea's northern shore—high in some places, low in others—was indented by several large bays. The low-lying and irregular eastern shores were interrupted in the north by the huge delta of the Syr Darya and in the south were bordered by a wide tract of shallow water. The equally vast Amu Darya delta lay on the lake's southern shore, and along the lake's western periphery extended the almost unbroken eastern edge of the 820-foot- (250-metre-) high Ustyurt Plateau. Shrinkage of the Aral Sea, 1960--99.From about 1960 the Aral Sea's water level was systematically and drastically reduced because of the diversion of water from the Amu Darya and Syr Darya rivers for purposes of agricultural irrigation.
