The current west of 10°W has a mean speed of O.5 knot and may at 
times exceed 2.0 knots in the prevailing south direction. In this 
region also, there is no significant seasonal change in current speed, 
but the percent distribution of observations during summer is higher 
(55 percent) than during winter (45 percent). The distribution of 
observations in the other directions averages about 9 percent. 
Little is known about subsurface flow. Currents computed in June 
at 41.5°N, 14.5°W show that the flow is generally south-southeast at 
about O.4 knot near the surface; speeds gradually decrease to about 
0.1 knot near the bottom at about 5,300 meters (17,388 feet).
