influenced by the Canary Current, widens considerably between 10° 
and 20°W. Figure 21 shows the approximate winter boundaries and 
the variations of the current by percent of observations in the 
prevailing directions and mean speeds. 
The approximate seasonal migration of the southern boundary of 
the Guinea Current by latitude along the meridian 10°W is shown as 
follows: |

Little information is available on subsurface flow. The current 
profile shown in Figure 21 compares favorably with known or typical 
characteristics of the current in this region.
