The object of research marine environment of the Azov-Black Sea basin. The purpose of the work: new knowledge about the processes and events that occur in ecosystems of the Azov-Black Sea basin in the face of increasing anthropogenic influence and global climate changes, the development of practical recommendations for the preservation of the natural resource potential of marine areas of Ukraine. Research Methods: complex hydrological and hydrochemical expeditions with contact measurement techniques, automated monitoring of the marine environment parameters with the help of independent gauges, GPS - measurements of shoreline, geomorphological description of the coast. The main results: 1. Estimated semicentennial trends in the stratification of the Black Sea waters. They are characterized by a positive trend in the upper layer of the sea and negative - in the intermediate layers. Vertical density gradient in the upper layer has increased in 60 years by 20%. The main reason for this - the desalination of the top layer, which occurs mainly in the summer due to the reduction of evaporation and regional climate changes. This indicates a weakening of the ventilation in intermediate waters of the Black Sea, explains the unprecedented reduction in the oxygen content in the intermediate layer and shows the dangerous trends in the functioning of marine biota. 2. Investigation of the influence of mud volcanoes in the Black Sea showed no effect on the distribution of hydrochemical characteristics, including the distribution of hydrogen sulfide. 3. The monitoring of water of the Sevastopol Bay in South Bay identified anthropogenic source of surface water pollution by nitrates and nitrites. Over the last three years it have seen the dominance of the organic component of the carbon cycle in the bay, which indicates a high level of anthropogenic pollution. Bottom layers of the bay waters are characterized by lack of oxygen, sediments of the bay are characterized high levels of heavy metal contamination. 4. In the Kerch Strait the basic hydrological fields were measured, which showed that in the narrowness near island Tuzla there is an intensification of currents up to 70-80 cm/s, which led to the formation of new shoals north of the dam. 5. First according to the high-precision GPS-measurements of the shoreline the sign and its rate of interannual changes in the Western Crimea were determined, profiles of beaches and underwater slope were obtained. Recorded the fact that the formation of a new island in the Black Sea as a result of separation of the distal part of the Bakal Spit from the main body. Keywords: Azov-Black Sea Basin, comprehensive monitoring, stationary oceanographic platform, hydrological, hydrochemical and hydrooptical measurements, GPS-measurements of costal line, the structure of bottom sediments.
