The contribution of the anticyclones separated from the coast to the water exchange between the coastal zone and the deep-water basin is caused by the entrainment of the coastal waters and their transfer to the open sea as well as by the formation of associated eddies and jets at the peripheries of the anticyclones. For example, waters with relatively low salinity (18.15 psu, at a salinity of the surrounding waters of 18.25 psu) of an evidently coastal origin were observed at the center of an anticyclonic eddy in November 1993, three months after its separation from the coast [23]. The reduced salinity of the waters of an evidently coastal origin observed in separating anticyclonic meanders and eddies was also noted in [5,11]. The advection of the surrounding waters at the periphery of the eddies at distances of about 150 km also represents an important mechanism for the water exchange between the shelf and the open sea. 

Local synoptic wind impacts also favor the intensification of the horizontal water exchange in the Black Sea. For example, they cause wind effected phenomena and formation of filaments of coastal upwellings and provide the separation of coastal anticyclones from the eastern coast (under northerly winds) or removal of the shelf waters to the deep-water basin by anticyclones over the northwestern continental slope (under westerly winds).
