Hydrologic and hydrochemical condition of the mid-Caspian Sea

Sakinat A. Guseinova


Background and Objective: The author surveys the research papers investigating the differences in the temperature and salt levels in the sea and ocean waters depending on the space-time factors as well as rivers inflow. These differences are explained by the fact that ocean and marine areas have a high density of biological resources, as well as an anthropogenic load. Methods: Current data on the hydrochemical condition of the mid-Caspian Sea as a whole and its individual regions allocated to the exploration and development of oil fields show that this condition is formed mainly under the influence of natural processes. Results: Analytically defined silicon form in sea water is metasilicon acid. Except the dissolved state, silicon is in sea water in the form of colloidal solutions of polysilicon acids. Variability of silicon concentration in natural waters generally depends on processes of diatomic seaweed activity and its destruction. Conclusion: The author concludes that the hydrochemical condition of the marine environment within the range of inherent fluctuations does not hamper the development of oil fields on the Caspian shelf.
