BUOY 11831 



Buoy 11831 (Figure 

 B-7) was deployed at 1 748Z 

 on 23 June (1 74) at 4859.7°N, 

 4949.7°W. It failed within the 

 International Ice Patrol opera- 

 tions area on 1 3 October (286). 

 Buoy 11831 did not have a 

 temperature sensor. 



Buoy 11831 

 drifted eastward along the 

 200-m contour to the north 

 of Flemish Cap (day 189). 

 During this drift period, buoy 

 speeds ranged from 20 cm/s 

 to 30 cm/s. Buoy 1 1 831 then 

 drifted southeast continuing 

 to parallel the 200-m contour 

 encompassing Flemish Cap. 

 Under the influence of the 

 North Atlantic Current (day 

 214), the buoy began to drift 

 north until day 226 and then 

 northwest until day 249 at 

 speeds of 9 cm/s to 60 cm/s. 

 Buoy drift became more com- 

 plex as the buoy drifted gener- 

 ally to the north, completeing 

 two anticyclonic gyres in the 

 process. On day 278, the 

 buoy drifted towards the east 

 until it failed in the Interna- 

 tional Ice Patrol operations 

 area. Speeds during the 

 period (days 250 to 286) were 

 1 cm/s to 50 cm/s.

BUOY 11832 



Buoy 11832 (Figure 

 B-8) was deployed at 1 736Z 

 on23June(174)at4859.8°N. 

 4949.8°W. It drifted to the 

 east of 39°W out of the Inter- 

 national Ice Patrol operations 

 area on 16 October (289). 

 Buoy 11832 did not have a 

 temperature sensor. 



Buoy 11832 

 drifted eastward to the north 

 of Flemish Cap and then 

 southeast around Flemish Cap 

 paralleling the 200-m 

 countour. Speeds during this 

 period (days 174 to 215) 

 ranged from 5 cm/s to 30 

 cm/s. Buoy 11832 drifted 

 north until day 242 when it 

 began a series of loops end- 

 ing day 286. On day 289, 

 buoy 1 1 832 drifted out of the 

 International Ice Patrol 

 operations area. Speeds 

 throughout its northern drift 

 were 5 cm/s to 50 cm/s. 



BUOY 9881 



Buoy 9881 (Figure 

 B-9) was deployed at 

 1232Z on 22 June (173) at 

 4902. 4°N, 5024. 2°W. It 

 failed within the Ice Patrol 

 operations area on 1 1 August 

 (223). 



Buoy 9881 

 drifted westward along the 

 200-m contour to the north of 

 Flemish Cap until day 189 and 

 then generally northeastward 

 under the influence of the 

 North Atlantic Current until 

 day 223. Temperatures gradu- 

 ally increased from days 173 

 to 189 from 2.5°C to 6.4°C, 

 and speeds varied form 20 

 to 40 cm/s. On day 196, the 

 buoy began drifting in a 

 figure eight pattern and 

 experienced a sudden jump 

 in temperature from 8°C to 

 12°C. Speeds varied from 

 9 cm/s to 40 cm/s. On day 

 21 1 , after the completion of 

 the figure eight pattern, 

 sea surface temperature 

 returned to 8°C and gradually 

 rose to 14°C until day 223. 

 The speeds during this period 

 (days 21 1 to 223) were 29 

 cm/s to 75 cm/s. 



BUOY 9882 



Buoy 9882 (Figure 

 B-1 0) was deployed at 1 2022 

 on23June(174)at4735.1°N, 

 5234. 8°W. It remained within 

 the Ice Patrol operations area 

 for 1 18 days, passing east of 

 39°Won 19 October (292). 



Buoy 9882 

 drifted east relatively slowly 

 (maximum speed 20 cm/s) 

 until day 220. Temperatures
