Finally, the wide availability of oceanographic 

 information now on the internet enables IIP 

 personnel to focus on iceberg reconnaissance. 



In 2006, IIP collected oceanographic 

 data from air- and ship-deployed satellite- 

 tracked drifting buoys. Satellite-tracked 

 drifting WOCE buoys, drogued at a depth of 

 fifteen or fifty meters, provided near real-time 

 ocean-current information. Ice Patrol deployed 

 WOCE buoys on the Grand Banks and in the 

 offshore and inshore branches of the Labrador 

 Current and used data from these buoys to 

 modify the historical-current database within 

 HP's computer model. 



During 2006, IIP deployed nine 

 satellite-tracked drifting buoys - five from 

 reconnaissance aircraft and four from Canadian 

 Coast Guard ships (Figure 12).

 Buoy Drift Track Atlas, which is available upon
