Using a vessel-mounted ADCP and a CTD, water current profiles and, physical oceanographic parameters are measured, respectively. The results show that a small scale anticyclone eddy (warm core) is generated in the area that its core had at least 0.5 ℃ temperature difference from surrounding waters. The main current direction was westward and at location of the eddy, changes in current direction are observable. The minimum quantity of nutrients is observed at the eddy core and this means that at study area downwelling phenomenon is occurred. CP - IRAN IN - No.3, Etemad Zadeh St., Fatemi Ave., Tehran, IR.
