reports submitted by merchant vessels 

 contained ice information, those that did 

 (55 ice reports) still constituted 23% of the 

 ice reports received by IIP (Figure 3). 



The Canadian Government provided 

 the next highest number of reports with 

 17% of total reports and 56% of the ice 

 reports received by IIP (Figures 2, 3). The 

 Canadian Government category 



encompasses reporting from the CIS 

 reconnaissance airplane, contract 

 reconnaissance flights by Provincial 

 Airlines, HMCS vessels at sea, and coastal 

 lighthouses (Table 1). CIS conducts ice 

 reconnaissance using a SLAR-equipped 

 Dash-7 airplane, focusing primarily on sea 

 ice. Provincial Airlines is a private 

 company that provides reconnaissance 

 services on contract to DFO throughout the 

 year, to CIS from June through December 

 and to the offshore oil industry. DFO 

 flights by Provincial Airlines monitor fishing 

 vessel activity, frequently carrying them 

 into areas of high iceberg concentrations.

The reporting source that was 

 responsible for the most targets being 

 merged into HP's BAPS model was from 

 BAPS transferred targets. During the 2001 

 ice season, 46% of the targets in MP's 

 model came from BAPS transfers. These 

 targets are those that are originally sighted 

 north of 52°N and are passed on to HP's 

 model when they cross this line between 

 HP's area of responsibility and that of the 

 Canadian Ice Service. The configuration of 

 the BAPS model makes determining the 

 original sources for targets of this type 

 extremely cumbersome. Consequently, 

 no attempt is made to determine the 

 original sighting source of targets 

 transferred to IIP in this manner. 

 Therefore, although the BAPS category 

 accounted for 46% of merged targets, it did 

 not represent any reports submitted to IIP. 



The source with the second most 

 targets merged into HP's BAPS model was 

 the Canadian Government with 21% 

 (Figure 4). Part of the reason for this is 

 that this category includes the use of aerial 

 reconnaissance to cover a larger area in a 

 shorter time. As a result, these reports 

 usually contain multiple targets within the 

 same report in comparison to ships that 

 report fewer, if any, targets per report. 

 Ships, which accounted for 23% of ice 

 reports, provided 14% of merged targets 

 (Figures 3, 4). Finally, the National Ice 

 Center and IIP accounted for 10% and 9% 

 of targets merged into the BAPS model, 

 respectively. The continued success and 

 viability of the International Ice Patrol
