Abstract
The low salinity of the Antarctic Intermediate Water (AAIW) extends eastward across the South Atlantic just south of the equator (3-4°S). Evidence of a weak eastward flow just north of the equator (1-2°N) is also shown. Lateral and vertical homogenization of properties in the AAIW is found at the equator between 2°S and 2°N. Observations suggest enhanced mixing within the equatorial baroclinic deformation radius. The South Atlantic tropical gyre is shown to consist of the following three cells: one cyclonic cell centered at about 7°S, another centered at about 19°S in the west and 23°S in the east, and one anticyclonic cell centered at about 13°S. These cells are associated with a westward extension at 10°S of high salinity and low oxygen which originates in the eastern tropical South Atlantic and a front in these properties at about 15°S in the west and about 20°S in the east. -from Authors
