The final TOD of the 1984 

 season, TOD #4530, was 

 deployed on 6 August (219) in 

 the center of the Flemish Pass in 

 position 46046.8'N 46054.4'W. It 

 drifted south at 1 cm/s until 8 

 August (221). It then drifted 

 north around the top of the 

 Flemish Cap and continued to 

 follow the bathymetry south down 

 the east side of the Cap until 23 

 September (267). The average 

 velocity around the Cap was 22 

 cm/s. Kollmeyer (1966) had 

 reported the presence of a north 

 flowing counter current in the 

 Flemish Pass. This drift was 

 similar to that found by Shuhy 

 (1981). After 23 September 

 (267), TOD #4530 began drifting 

 with the North Atlantic Current 

 towards the northeast at an 

 average velocity of 64 cm/s. 



The 1984 TOD'S clearly 

 demonstrate the variability of the 

 flow field in the vicinity of the 

 Grand Banks. The differences in 

 TOD tracks #451 0, #2633, 

 #2632, #4530, and #4531 

 indicate that the axis of the North 

 Atlantic Current migrates east and 

 west in the area northeast of the 

 Flemish Cap. The velocity 

 distribution of TOD #451 2 is 

 significantly different from the 

 remaining distributions (Figure B- 

 2). It was the only TOD that 

 remained in either the Labrador 

 Current or the North Atlantic 

 Current for its duration in the 

 International Ice Patrol operating 

 area. Considering the variability 

 of the flow field, TOD's are 

 essential to International Ice 

 Patrol's ability to successfully 

 predict the movements of 

 icebergs in the Grand Banks area.
