The results of contouring the dynamic 

 heights of cruises 1-lA, 2-lB, and 3-lC are 

 illustrated in figures 11 and 12. They show 

 a small intense eddy approximately 100 miles 

 to the northeast of the Yucatan Channel. 

 It may also be observed that the Yucatan 

 current flows a considerable distance to the 

 northwest (300 miles) before turning south 

 and east and departing through the Florida 

 Straits. A second, less intense, anti- 

 cyclonic eddy is pictured approximately 100 

 miles off Pensacola, Florida. Each of the 

 two eddies described above is a consequence 

 of the combined analysis of two cruises 

 taken several weeks apart and consisting of 

 only a small number of stations. Therefore, 

 the resulting composite analysis may lac^ 



detail and continuity in time and space. 



Cruise 4-2A (in the winter of 1952), 

 graphically shows for the first time the 

 existence of a large-scale, anti-cyclonic 

 eddy centered at 86" 36' West longitude and 

 26' 00' North latitude. See figure 13 for 

 the surface current pattern. The analysis 

 here is likely to be more indicative of a 

 synoptic current pattern inasmuch as the 

 period of the cruise in the region of the 

 eddy was about two weeks. It should also 

 be noted that the eddy shown in figure 13 

 is somewhat obscured in figures 11 and 12 

 by the contouring of dynamic height data 

 from two separate cruises (cruises 1-lA tind 

 3-lC).
