As it is divided vertically into three layers: the upper, middle and bottom. At the bottom layer of life, because from the surface of the seabed allocated poisonous hydrogen sulfide.
Black Sea at all times of the Russian state was a favorite place for its residents. This is understandable, because this rare summer storm, there is almost no hazard to humans of marine animals, the sea is a small and malosolenoe because it runs on several large freshwater rivers and many smaller, but it is quite good “holds” on the surface, so good here learn to dive and the first to discover the wonders of underwater world. As it is divided vertically into three layers: the upper, middle and bottom.
At the bottom layer of life, because from the surface of the seabed allocated poisonous hydrogen sulfide. In addition to individual species of bacteria, the absence of oxygen does not withstand even the deep-sea fish. The upper layer is believed to extend to a depth of 40-60 m and is subject to strong seasonal fluctuations in temperature. In winter, it reaches up to 7 C and 24 C in summer, off the coast of the Caucasus as the sea and is already warming up to 30C and is best suited for family holidays with children.
With increasing depth of water temperature fluctuations are reduced, so that at a depth of 40 m in winter temperature is 8 C and 11 C in summer, and the middle layer has a lower salinity than the lower hydrogen sulphide. It extends to a depth of 100-140 meters, after which begins this cold. Hour the temperature is 6-8 degrees.
Black Sea, as is known, an internal sea, which means that it is surrounded by land and through the Dardanelles strait connects with the Mediterranean Sea.
