The SAC is the southernmost limit of the South Atlantic Subtropical Gyre and presents strong interaction with other currents such as the Antarctic Circumpolar Current (ACC). The data were processed according to the Taylors theory. The velocity field map for the study area as well as the mean ...
It ap- pears that Pacific waters mix by a nearly isopycnal pro- cess with the relatively warm, saline North Atlantic deep water to the north and the relatively cold, fresher Wed- dell Gyre waters to the south. Fine structure and large- scale gradients indicate that the mixing is quite ...
At intermediate levels, these northward currents trace the flow of Antarctic Intermediate Water (AAIW) equatorward, though even more AAIW is seen to recirculate poleward in the subtropical gyre. In spite of the model's rather coarse resolution, some subtle features of the Brazil-Malvinas ...
Using the regional freshwater balance, gyre thermocline residence time is determined to be between 4.4 and 8.5 years, implying an oxygen utilization of 0.3-0.5 mll-1 y-1 . Below the thermocline there is some evidence for southward Plow of North Atlantic Deep Water along the eastern boundary. ...

The major features of the South Atlantic circulation are described and analyzed, with special emphasis on the Brazil-Malvinas Confluence region, the Subtropical Gyre with the formation of frontal structures, and the Agulhas Retroflection. The Agulhas eddy-shedding process has been studied extensively. ...
An investigation of the bio-optical properties of the South Atlantic subtropical gyre (SASG) was conducted using data primarily from the UK Atlantic Meridional Transect (AMT) program and SeaWiFS. The AMT cruises extend from the UK to the Falklands Islands (sailing on the RRS James Clark Ross) ...
(diabatic). Other ocean circulation systems can impact, and can be impacted by, the overturning circulation, such as the South Atlantic subtropical gyre32,116and the subtropical cells115. Due to diverse air-sea interaction processes, the upper layer is composed of water masses originating at the...
The upper limb of the Atlantic meridional overturning circulation brings shallow interocean contributions to replenish the North Atlantic export of deepwaters. It is primarily formed in the southern South Atlantic where the converging entrainment of Paci
SASTMW 3 is formed along the southern edge of the gyre, more concentrated to the east of 5E, and between 10W and 35W. Much of this mode water forma- tion is associated with the location of the North and South subtropical fronts which encompass the South Atlantic Current, the ...
