Figure 2 Sources of reports received in 2000, 

 including ice, "no ice", and SST reports 



"no ice", stationary radar target, and sea 

 surface temperature reports. In Appendix 

 B, a single report may contain multiple 

 targets. In 2000, the merchant vessel that 

 provided the most reports was MN CSO 

 Marianos, submitting 77 separate reports. 

 Though not all of the 1 ,445 information 

 reports submitted by merchant vessels 

 contained ice information, those that did 

 (427 ice reports) still comprised 57% of the 

 ice reports received by IIP (Figure 3). 



The Canadian Government provided 

 the next highest number of reports with 

 17.4% of total reports and 31 .8% of the ice 

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

encompasses reporting from the CIS 

 reconnaissance airplane, contract 

 reconnaissance flights by Provincial 

 Airlines, HMCS vessels at sea, and coastal 

 lighthouses. 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 sources that detected 

 the most icebergs are those that included 

 aerial reconnaissance since this method 

 allows for covering the most ocean area. 

 The sources with the most targets merged 

 into HP's BAPS model were the Canadian 

 Government with 40.3% and IIP with 

 23.5% (Figure 4). Due to the ability of 

 aerial reconnaissance to cover a larger 

 area in a shorter time, their reports usually 

 contain multiple targets within the same 

 report in comparison to ships that report 

 fewer, if any, targets per report. IIP, which 

 accounted for only 7.6% of ice reports, 

 provided 23.5% of targets merged into the 

 BAPS model. Ships, which accounted for 

 57% of ice reports, provided 8% of merged 

 targets (Figures 3,4). Admittedly, data 

 transfers from CIS to IIP (BAPS category)
