THE INFLUENCE OF THE CURRENT SYSTEMS AND LATERAL MIXING UPON ANTARCTIC INTERMEDIATE WATER IN THE SOUTH ATLANTIC
Previous investigations of the Antarctic Intermediate Water (AAIW) are summarized. It is concluded that the northern edge of the convergence of the Antarctic and sub-Antarctic waters is the source of the AAIW. Study of the major currents of the southwestern South Atlantic (Circumpolar, Falkland, and...
