TOD #451 was deployed north 

 of the Flemish Pass on 25 March 

 (085) in position 49°N 

 47°58.2'W. This deployment 

 position was in about one tenth 

 sea ice cover. It proceeded east 

 around the top of the Flemish 

 Cap and followed the 2000m 

 contour south around the eastern 

 side of Flemish Cap at an average 

 velocity of 1 7 cm/s until 4 May 

 (125). On 4 May (125), TOD 

 #451 sharply altered its drift 

 track and began drifting north and 

 then northwest after crossing 



49°N at an average velocity of 46 

 cm/s. Sea surface temperature 

 charts and the drift indicate that 

 TOD #451 entered the North 

 Atlantic Current on 4 May (1 25). 

 The SST data from the TOD also 

 confirms that TOD #451 entered 

 the North Atlantic Current. The 

 drift pattern of TOD #451 from 4 

 May (1 25) until it crossed 520N on 

 22May (143)issimilartothose 

 described in previous years 

 (Anderson, 1983a and Summy, 

 1982). TOD #4510 remained 

 above 52°N until 8 September 

 (252). While above 520N, TOD

#451 was caught in an 

 anticyclonic eddy that was 

 centered near53O30'N 48O00'W 

 before heading south on 29 

 August (241). From 1 September 

 until 20 September (245-264), 

 TOD #451 0's motion was 

 anticyclonic, apparently caught in 

 the same eddy as TOD #4509. 

 No signal was received from TOD 

 #451 after 20 September (264). 



TOD #451 2 was deployed at the 

 northern end of the Flemish Pass 

 on 27 April ( 1 1 8) in position 

 47051 .6'N 4703O.OW. TOD 

 #451 2 essentially followed the 

 bathymetry south to the Tail of 

 the Bank at an average velocity of 

 33cnVs. On 24 May (145), TOD 

 #451 2 was caught up in the North 

 Atlantic Current and began 

 moving northeast. It was caught 

 in a cyclonic eddy between 6 

 June and 27 June (158-179) 

 (average velocity in eddy was 35 

 cm/s; radius of motion about 90 

 km). The METOC SST charts 

 indicated the presence of two 

 warm core (anticyclonic) eddies in 

 the area where TOD #451 2 

 exhibited cyclonic motion (Figure 

 B-3). It continued drifting to the 

 northeast at an average velocity 

 of 74 cm/s. TOD #451 2 exited 

 the International Ice Patrol region 

 at 46°41 'N 39000'W on 1 4 July 

 (196). 



TOD #4514 was deployed in the 

 northern area of the Avalon 

 Channel on 28 April (1 1 9) in 

 position 48° 15'N52O20'W. It 

 drifted slowly to the southwest at 

 an average velocity of 1 4 cm/s 

 until 7 May (128). No further
