ABSTRACT 



Geomagnetic Electrokinetograph (GEK) observations by the USS 

 PURSUIT, USS SAN PABLO, and RV ATLANTIS, and 21 oceanographic 

 stations by the USS PURSUIT were obtained in the northern Caribbean 

 area bounded by Cuba, Hispaniola, and Jamaica between 14 March and 

 9 June 1953. .< , 



The current system was found to be more complex than previously 

 believed; current speeds were strong, often exceeding one knot, and an 

 easterly drift along the southern coast of Cuba was observed at all times. 

 Volume transport above 920 meters was calculated as 45 X 10 6 m 3 /sec. 



It is believed that the current system was undergoing change during 

 both parts of the PURSUIT survey, since the subsequent surveys by the 

 ATLANTIS and SAN PABLO found a reversed pattern of flow. Calculations 

 of transport (excluding those sections where stations taken at both the 

 beginning and the end of the survey were used in the computations) 

 support the accepted theory of water movement from east to west. How- 

 ever, surface current measurements indicate a definite eastward drift. 



The validity of dynamic calculations based on USS PURSUIT oceano- 

 graphic station data is questionable in certain sections of the area owing to 

 the transient nature of the circulation and the long period of time between 

 occupation of the stations.
