Horizontal Water Circulation in Pacific Sector of the Southern Ocean (Gorizontalnaya Tsirkulyatsiya Vod v Tikhookeanskom Sektore Yuzhnogo Okeana),
Abstract
The Antarctic Circumpolar Current can be clearly distinguished in the complex system of cyclonic and anticyclonic water movements which dominates the Pacific sector of the Southern Ocean. The depth of the current is considerable: at places it can be traced to 3000m. Several branches are formed flowing southward and northward. Three branches are formed on the southern periphery; one flowing southward into the Bellingshausen Sea, the other flowing into the Amundsen Sea and the third flowing into the Ross Sea. Cyclonic water movements are formed in places where these branches join the coastal Antarctic Current. As a result, the water is separated into two parts, one joins the system of cyclonic and anticyclonic circulations while the other part joins the coastal current. Two branches are formed on the northern periphery of the Eastern Circumpolar Current. The largest one flows northward, giving rise to the Peru Current, the smaller one flows toward the Tasman Sea. The maximum velocity of the current varies from 10 to 20cm/sec., reaching 30cm/sec. (Author)
