THE LAYERED STRUCTURE OF CURRENTS AND THE VERTICAL EXCHANGE IN THE BLACK-SEA

The results of experimental research of currents and vertical hydrolog ic structure in the Black Sea are considered. It is shown, that the ve rtical structure of currents has a well expressed layered structure, c onnected with termochaline stratification. In many cases an Undercurre nt is observed on the depths 100 - 300 m under the Main Blacksea Curre nt. The estimations of the coefficient of vertical exchange, agree wit h the values obtained by other methods. On the basis of correlation be tween vertical gradients of currents and density a relatively simple r elation for the coefficient of vertical exchange is suggested.
