Space monitoring of Aral Sea degradation

The results of remote sensing survey of the Aral Sea in its degradation period are given. Satellite images are used to map shoreline retreat from 1961 to 2008 and to measure the decrease in the area. Seasonal variations in shoreline and water area are identified, suggesting seasonal level variations and correlating well with data of satellite altimetry surveys of sea level. Observations covered surge phenomena, seasonal dynamics of landscapes, and the seasonal salinization rhythm in coastal territories with the subsequent formation and weathering of salt crusts. The character of river runoff input into the Great Sea resulting from overbank flooding in artificial water bodies in the Amu Darya delta is identified.
