Merged Targets 



The 480 ice reports received by IIP 

 contained 2,142 targets that were merged 

 into the drift and deterioration modeling 

 system operated jointly between CIS and 

 IIP (BAPS). The source responsible for 

 reporting the most targets that were 

 merged into HP's BAPS model was the 

 Canadian Government with 40%. BAPS 

 transferred targets accounted for 31% of 

 the targets in HP's model. These targets 

 were originally sighted north of MP's AOR 

 and then were passed to MP's model when 

 they drifted south of 52°N. 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 via BAPS; so for 

 statistical purposes BAPS does not submit 

 reports to IIP and was not noted in Figures 

 2 or 3. IIP accounted for 19% of merged 

 targets, merchant shipping 8% and the 

 National Ice Center 2% (Figure 4).

of its resources in searching for the 

 icebergs that are the most seaward. 

 Therefore, the initial sighting source for 

 icebergs that determine the LAKI is very 

 interesting. IIP detected 43% of LAKI 

 icebergs (Figure 5). However, IIP also 

 benefited significantly from the participation 

 of ships of opportunity and from HP's 

 partnership with the National Ice Center. 

 The merchant shipping industry was the 

 original reporting source of 22% of LAKI 

 icebergs and NIC reported another 5%. 

 Finally, BAPS model transfers between IIP 

 and the Canadian Ice Service accounted 

 for 3% of LAKI icebergs.

LAKI Iceberg Sightings 



Since IIP is mandated by SOLAS to 

 guard the Southeast, South, and 

 Southwest regions of the Grand Banks, IIP 

 closely monitors those icebergs that set the 

 limits. Additionally, IIP spends the majority 



Slightly different from previous 

 years, changes to SOLAS required ships to 

 make use of International Ice Patrol 

 services while in the IIP AOR. Throughout 

 the iceberg season, IIP produced two 

 products a day (OOOOZ and 1200Z) and 

 distributed them by a wide variety of 

 methods. Vessels could have received 

 text ice bulletins at OOOOZ and 1200Z daily 

 to inform them of the Limit of All Known 

 Ice. U. S. Coast Guard Communications 

 Area Master Station Atlantic/NMF and 

 Canadian Coast Guard Marine 

 Communications and Traffic Service St. 

 John'sA/ON were the primary radio 

 stations responsible for the dissemination 

 of ice bulletins. In addition, ice bulletins 

 and safety broadcasts were delivered over 

 the Inmarsat-C SafetyNET via the Atlantic 

 East and West satellites. Another
