CONCLUSIONS 



A coincidental increase in southward flow of 

 Labrador Current water and northward flow of 

 North Atlantic Current water between the first 

 and second Intensive Surveys caused a reversal 

 in the slight residual off slope flow along the 

 western boundary to a sizable 1.264 x lO^in^s"' on 

 slope component and a broadening of the dynamic 

 low in the top center of the survey area. A 

 decrease in volume transport of the North At- 

 lantic Current from the second to the third In- 

 tensive Survey resulted in a deepening of the 

 trough which then extended to the southernmost 

 two sections. The reduced North Atlantic Cur- 



rent flow most probably ensued from the south- 

 easterly excursion of a meander; in fact, the 

 entire pattern of volume flow changes during the 

 three intensive surveys could be explained by the 

 passage of the crest of a meander typical to the 

 area, or could merely be a southeasterly retreat 

 of the main axis of the North Atlantic Current. 

 However, neither mode can be proved by the 

 available data. Finally, the Labrador Current 

 entering from the north was allowed to infiltrate 

 the area to its greatest extent with the highest 

 percentage of Cold Core water passing through 

 tlie southernmost section.
