tor the activities of fishing vessels, frequently carry 

 them to areas with high iceberg concentrations. 

 The next largest contribution to the air reconnais- 

 sance total was from IIP ICERECDETs. IIP flights 

 concentrate on defining the boundaries of the ice- 

 berg distribution. These are typically areas of low 

 iceberg concentration. Table 2 shows the impor- 

 tant contribution of IIP reconnaissance in deter- 

 mining the limits of all known ice (LAKI). The at- 

 tributes of the individual icebergs that set the LAKI 

 are described in Appendix C. BAPS sightings are 



icebergs detected north of 52°N primarily by AES 

 reconnaissance. These are passed to IIP by AES 

 as the icebergs are predicted to have crossed into 

 the Ice Patrol operating area. AES acquired and 

 relayed to IIP iceberg information obtained dur- 

 ing sea ice reconnaissance flights and a few flights 

 dedicated solely to iceberg reconnaissance. 



During 1996, the IIP Operations Center 

 received a total of 3902 target sightings within its 

 operations area which were entered into MP's drift
