Characteristics of the circumpolar current in the Pacific Ocean
Abstract
As the result of measurements made with the electromagnetic probe of currents (EMIT) during the third cruise of the Marine Antarctic Expedition on the R/V «Ob», characteristics were obtained (direction and velocity) of the Circumpolar Current on the surface of the Southern Pacific in the area from 166° E to the Drake Passage. These data (327 vectors of currents) provide information about the velocities and direction of the Circumpolar Current during the latitude and meridional atmospheric circulation in the 1atitude belt between 40° and 65° S. A comparison is made between the data obtained with instruments and the scheme of the current in the Sea Atlas, Vol. II. On the greater part of the region under study the data obtained by the instruments coincide with the scheme of current. The deviations from the scheme were due to the breaks in the prevalent latitude type of, atmospheric circulation by the meridional type, which was observed on 160° W from 66° to 45° S.
