Title of the Manuscript Changes of Water Temperature and Salinity of the Caspian Sea during the XX Century
The paper considers the geoinformation system of the Caspian Sea, which includes the mega database of primary oceanographic and meteorological information for period 1914–2010, historical cartography information and modules for spatio-temporal analysis. Based on this mega database the average annual vertical climatic sections of the salinity and water temperature and anomalies of them for specific periods were created. The new quantitative and qualitative changes, occurred during the XX century in the structure of sea water, were described. The simplified scheme of water exchange between various areas at different positions of the sea level were proposed.
