high iceberg concentrations. The next largest con- 

 tribution to the air reconnaissance total was from 

 IIP ICERECDETs. IIP flights concentrate on de- 

 fining the boundaries of the iceberg distribution. 

 These are typically areas of low iceberg concen- 

 tration. Table 2 shows the important contribution 

 of IIP reconnaissance in determining the limits of 

 all known ice (LAKI). The attributes of the indi- 

 vidual icebergs that set the LAKI are described in 

 Appendix C. BAPS sightings are icebergs de- 

 tected north of 52°N primarily by CIS reconnais- 



sance. These are passed to IIP by CIS when 

 icebergs are predicted to have crossed into the 

 Ice Patrol operating area. CIS provided IIP with 

 iceberg information obtained during sea ice re- 

 connaissance flights and a few flights dedicated 

 solely to iceberg reconnaissance. 



During 1997, the IIP Operations Center 

 received a total of 4829 target sightings within its 

 operations area which were entered into HP's drift 

 model. This is about 20% more than the 3902
