Three sets of recent data from the Southern Ocean, on mass transport through the Drake Passage (Whitworth et al., 1982), on surface winds (Jenne et al., 1971; Han and Lee, 1981) and on density (Gordon et al., 1978) allow an instructive look at the dynamics of the Antarctic Circumpolar Current. These new data suggest that the simple Sverdrup balance of wind stress curl driving a poleward flow south of about 50S as first proposed by Stommel (1957) is consistent with the observed transport within experimental uncertainties....
