Abstract

Over the past five decades, the Aral Sea, as the world's fourth largest lake, has a rapid decline of area, a serious decline in quality of the environment and has a devastating impact on most of the Central Asian region. Although the water level of the Aral Sea descent lasted relatively short but had significant changes, in order to understand the detailed process of this change, we collected AS17 shallow drilling core holes from the northern Aral Sea in 1997. Through the comprehensive analysis of mineralogy, ostracods, pollen and other deposits environmental indicators, it shows that the core had a series of significant changes in mineralogical characteristics and biological characteristics, reveals three distinct phases that the Aral Sea depositional environment has experienced during the past nearly 500 years: increase decrease and again increase in salinity, and provides new evidence to the 15th century drought in the Aral Sea.
