Spiridonova E. Natural and anthropogenic changes in oceanological parameters of Kerch channel in nova days

On the basis of archive data and material of series of oceanographic, hydro-geological and ecological surveys realized by Southern Research Institute of Marine Fishery and Oceanography and Marine Hydrophysical Institute of Ukraine National Academy of Sciences, within two last decades, the state of the art of fields of major components of ecological complex in Kerch channel and on the Black and Azov Seas adjacent water areas is investigated. The natural changes in meteorological conditions and variations in waters circulation, thermohaline field, in fields of hydrochemical and hydrogeological elements and ice-reinforced conditions are reviewed. The influencing on channel ecosystem of anthropogenic factors - dredging activities and damping of soil, operation of ports and of road terminal points, Tuzla pier building is studied. Tendencies are detected and potent and rising anthropogenic press effect on Kerch channel ecosystem in conditions of interannual natural variations of large-scale hydrometeorological processes are estimated.The got results about of Kerch channel ecosystem components in modern condition and their forecast estimation is а central to development of the practical measures on its recovery and reduction of anthropogenic press. As well the results are useful in practice of the different branches of the Ukraine economic complex, in particular, in fish branch, navigation, in hydro technical construction, in resort and tourist mastering of the region, as well as at decision of the ecological problems.
