Regime of The Black Sea, the world's largest inland water body(Fig.l), is connected through the Bosphorus with a 50 meter sill to lie the Aegean and Mediterranean seas. It's characteristics include low salinity and stanionary halocline and lack of deep water movement important feature of the Black Sea is that %80 percent of its waters is anoxic. Since the Bosphorus is the only connection to the other seas, most of the physical and oceanographic parameters that hold for the couldn't be valid the Black Sea case. The Soviet hydrocomplex construction on the rivers of Black Sea pollutions have begun to change northern slope combined with water withdrawals for irrigation, municipalities and industries and pollutions. The Black Sea thermohaline structure and biota has started to change(Tolmazin,1985). Black Sea current, is 40–80 km wide encircles nearly around the sea at a distance of 20–150 km from the coastline. Geostrophic circulation is more intense in winter and reaches 40–45 cm/sn particularly below the seasonal thermocline(Batov, et al,1980). A few measurements (Filippov, 1968;Boguslavsky, et al,1976)indicate that actual average velocities in the mainstream are larger investigation of than purely geostrophic velocities(Fig.3) Therefore seawater physical and chemical parameters of the sea water relative velocities and mixing procedure in the Black Sea are important subjects for scientific research since 1982. These parameters and their variations have been recorded by IMST Institute's research vessel RV/K. Piri Reis in the waters of Turkish Economic zone. This paper describes a procedure for determining by means of the geostrophic method at selected stations. (Fig.1)
Current velocities and wave climate are important paremeters for the marine surveys and oceanographic studies. Field measurements of the ocean currents are difficult and expensive method. In a shallow water a moored ship can be used for this purpose to measure currents at several depths simultaneously.
