RV ATLANTIS (fig. 7). Eastward and southeastward drift occurs 

 throughout the central section; thence movement is southward between 

 Jaraaica and HLspaniola,, Currents set northeastward across Windward 

 Passage,, An eddy forms off Punta Ilaisi (Cape Maysi). Between 

 Windward Passage and Kispaniola, movement is southwestward and 

 thence southward. 



Between Jamaica and HLspaniola, where s^irface and subsurface 

 drogues were used in addition to the GEK, the ATIAMTIS found strong 

 southward currents in the top 200 meters. 



The two westernmost sections were obtained on 2u March and 6 

 through 8 April, reading from left to right. The earlier series of 

 observations showed all flow moving eastward. Subsequently, a de- 

 finite shift was noted, except along the southern coast of Cuba, 

 where the eastward drift persisted.
