Little information is available on subsurface currents. The 
speed of the southward flow decreases with depth, usually ranging 
between 0.2 and 0.4 knot at 30 meters (98 feet) and around 0.1 knot 
at 500 meters (1,640 feet). The current profile in Figure 26 shows 
the computed speed of the prevailing southward flow between the 
surface and 200 meters (656 feet).
