constant. About 60 percent of the 661 observations within the 
boundary of the current in January and February show a prevailing 
set east at a mean speed of 0.7 knot; maximum speed is about 2.0 
knots. Figure 30 shows the differences in extent of the current 
between winter and summer. 
Subsurface current data are negligible. Direct measurements 
inside the north boundary at 28.1°S, 19.3°W by the METEOR during 
13 to 15 August 1925 at depths of 30, 500, and 2,500 meters 
(98, 1,640, and 8,202 feet) showed sets in all directions but 
primarily southward. More than likely this flow is entrainment 
between the South Atlantic Current and the Atlantic South Equatorial 
Current,
