Figure D-4 Trajectories of 4555 and 4556, both of which were deployed north of Flemish Pass. 



The track of 4547 is remarkable in 

 that shortly after deployment it 

 moved southward and eventually 

 intersected the path of 451 1 . The 

 drifter tracks are in general 

 agreement with the surface 

 dynamic topography. 



CONCLUSIONS 



The data presented here show a 

 small, warm-core eddy centered at 

 43-50N, 48-20W and interacting 

 with the North Atlantic Current. 

 Although the detailed dynamics of 

 the eddy cannot be resolved by 

 the coarse sampling scheme, its 

 effect on the Labrador Current is 

 clear. During the period that the 

 eddy was close to the continental 

 slope (April-May), a portion of the 



Labrador Current departed tlie 

 slope and moved to the east at 

 about 44°N. 



The tracks of 4555 and 4556, 

 which were deployed in the 

 Labrador Current but moved 

 eastward off the slope at 44°N, 

 are consistent with the existence 

 of an eddy at this location. The 

 eddy had alnajor influence on the 

 Labrador Current as early as 20 

 April, and perhaps before.
