where it is quality controlled and 

 redistributed via oceanographic products. 



The satellite-tracked drifting buoys, 

 popularly known as WOCE buoys, are 

 drogued at a depth of either 15 or 50 

 meters and provide valuable current 

 information. The historical current 

 database used by HP's computer model is 

 modified weekly using the current 

 information from the drifting buoys. 



During the 2001 season, IIP 

 deployed seven satellite-tracked drifting 

 buoys, three from reconnaissance aircraft, 

 and four from volunteer ships. Figure 14 

 shows composite drift tracks for the buoys 

 deployed in 2001. No buoy recoveries 

 were planned or attempted. Detailed drifter 

 information is provided in HP's 2001 

 WOCE Buoy Drift Track Atlas that is 

 available from IIP upon request.
