across the bottom. The position 

 data presented and discussed in 

 this section are the raw data, not 

 filtered. The record was short 

 and the data return from the buoy 

 immediately after its deployment • 

 was poor (2-3 fixes per day) so 

 much of the interesting data 

 would be lost filling the filter. 



Buoy 4545 was deployed near 

 the 200 m isobath. During the 

 first 48 hours after deployment, it 

 moved onto the Grand Banks and 

 made an anticyclonic loop with a 

 diameter of about 35 km. Typical 

 buoy speeds during this period 

 were 30-40 cm/s. For the next 1 

 days (7-16 March, 66-75) it 

 moved southward through 

 Flemish Pass, near and parallel 

 to the 200 m isobath. Buoy 

 speeds during this period were 

 40-50 cm/s and the temperature 

 changed little (-0.8 to -1.4°C). 



On 16 f^arch (75), 4545 started to 

 move northwestward onto the 

 continental shelf. By 8 April (98) 

 the buoy had moved into a region 

 where it is likely that the drogue 

 was dragging on the bottom, so 

 the drift data after this date are of 

 little use. The surface tempera- 

 ture continued to increase slowly 

 but persistently. The surface 

 temperature when the buoy was 

 recovered was 3.3°C.
