core at 30 meters' depth (98 feet) the speed ranged between 0.6 and 
1.2 knots, averaging 0.9 knot; in the core or its immediate vicinity 
at 80 meters (263 feet), the speed ranged between 1.2 and 1.5 knots, 
averaging 1.3 knots. At 155 meters (509 feet) the flow appeared very 
weak and variable; near 400 meters (i, 312 feet) the flow below the 
core was westward at about 0.3 knot. A drogue released at 0°10'N, 
13°30'W, depth 55 meters (180 feet), showed the current setting east 
at 2.6 kmots. 
In view of the exaggerated vertical scale in Figure 4, the under- 
current appears to be a continuous flat ribbon flowing east between 
outer limits of about 1°N and 1°S beneath the west-setting Atlantic 
South Equatorial Current. The volume transport is estimated to be 
ho x 10°m3/sec.
