South Aral Sea Syr Darya, would be diverted in order to irrigate cotton and food crops in Kazakhstan and Uzbekistan. In 1986, due to an accelerated loss of water, the Aral Sea was split into northern and southern parts; the northern part is the current North Aral Sea. In 2007, the western basin had a salinity of 70 g/l and the eastern basin 100 g/l. Once the water level falls below the connecting channel (elevation 29 m), the salinities can be expected to diverge further. Under current conditions, the eastern basin may receive water from the Amu Darya in wet years, fluctuating in
Eustatic sea level ocean water mass (ice sheet runoff) • When an ice sheet such as Greenland begins to lose its ice mass due to melt, the liquid water is transported to the ocean. According to the ‘bathtub theory’, ice sheet runoff from Greenland will effect Eustatic sea level in all areas of the world whether proximal or distant. • Ocean water mass may also shrink in size if continental ice sheet grow in size, thereby removing liquid water from oceans and converting them to grow ice sheets 2. Changes in the size of the ocean basin (GIA: glacial isostatic adjustment) • The
