 Temperature Charts for the 

 indicated periods 



(Figure 0-3). The SST sensor on 

 TOD #4529 indicated between 

 1 1 °C and 1 3°C during this time 

 period. 



TOD#4529drittedtothe 

 northeast before turning south 

 and re-entering the IIP regfon on 

 24 September (267). After re- 

 entry, TOD #4529 drifted south 

 until 28 September (271 ) when it 

 turned cyclonically completing an 

 ellipse with a major axis length of 

 about 1 40 km on 6 October 

 (279). The average velocity 

 during the elliptical drift was 39 

 cm/s. TOD #4529 then drifted 

 slowly to the northwest exiting 

 the IIP region on 1 7 October 

 (289). As of 30 October, TOD 

 #4529 was still transmitting and 

 the drogue sensor indicated the 

 drogue was still attached. 



TOD #4550 



TOD #4550 was deployed in 

 about 750m of water north of the 

 Grand Bank on 29 July (21 0) in 

 position 50°30.0'N 50°29.4'W 

 (Figure 0-1). It drifted southeast 

 and then south with the Labrador 

 Current through the Flemish Pass 

 following the bathymetry until 20 

 August (232). During this 

 bathymetrically guided drift 

 period, the average velocity was 

 34 cm/s. TOD #4550 meandered 

 in a southeasterly direction at an 

 average velocity of 18 cm/s until 9 

 September (252). The SST 

 values retumed from TOD #4550 

 rose from 1 2°C to 1 7°C between 

 9 and 1 September indicating 

 TOD #4550 had been caught up 

 in the North Atlantic Current. 



The North Atlantic Current carried 

 TOD #4550 to the northeast at an 

 average velocity of 97 cm/s until it 



60
