Patrol operating area. As in 1992, AES flew 

 few iceberg reconnaissance flights during 

 1993 because of a lack of funding. AES did 

 acquire and relay to IIP some iceberg informa- 

 tion obtained during sea ice reconnaissance 

 flights and there were a few flights dedicated 

 solely to iceberg reconnaissance. 



During 1 993, the IIP Operations Center 

 received a total of 8058 target sightings within 

 its operations area and away from the New- 

 foundland coast which were entered into HP's 

 drift model. This can be compared to 3170 

 target sightings during 1992. The 8058 tar- 



gets entered into HP's drift model do not repre- 

 sent all ofthe targets reported to IIP. Sightings 

 of targets outside HP's operations area were 

 not entered into the model. Most of these were 

 farto the north of HP's area and were in areas 

 not covered by HP's model. 



Table 2 compares the icebergs de- 

 tected south of 48°N plus the number of ice- 

 bergs which were predicted to drift across 

 48°N for each month of 1 993 with the monthly 

 mean total from 1 983 - 1 992, the period during 

 which IIP has been patrolling with SLAR- 

 equipped aircraft. During the 1 993 ice year, an
