 include individual iceberg sightings, and 

 stationary radar target information. 



Merged Targets 



The 123 ice reports received by IIP 

 contained 125 targets that were merged into 

 BAPS, the drift and deterioration modeling 

 system operated jointly between CIS and IIP. 

 The Canadian Government reported 69% of the 

 targets merged into the BAPS model while the 

 merchant vessel fleet accounted for 25%, and 

 the IIP Ice Reconnaissance flights accounted 

 for 6% (Figure 4).

LAKI Iceberg Sightings 



SOLAS mandates that IIP guard the 

 southeastern, southern, and southwestern 

 regions of the Grand Banks. In doing so, IIP 

 develops a Limit of All Known Ice (LAKI) in 

 order to inform the mariner of the southernmost 

 limits of the iceberg population. IIP did not 

 create a LAKI in 2006 because there were no 

 iceberg incursions into the shipping lanes. No 



bergs were sighted or drifted south of 48°N, the 

 nominal northern extent of trans-Atlantic 

 shipping routes. Therefore, no LAKI iceberg 

 sightings occurred during this season. 



Products and Broadcasts 



IIP issued weekly ice chart and bulletin 

 updates each Friday from 17 February to 01 

 July. The ice chart and bulletin were both valid 

 for 1200Z. The ice chart was broadcast via HF 

 Fax at 0438Z, 1600Z, and 1810Z. Both 

 products stated that IIP was monitoring iceberg 

 conditions, but was not issuing daily products. 



Ice Patrol broadcast the weekly ice 

 chart and bulletin updates by the same means 

 that daily products are broadcast. U.S. Coast 

 Guard CAMSLANT/NMF and Canadian Coast 

 Guard Marine Communications and Traffic 

 Service St. John's/VON were the primary radio 

 stations that transmitted ice chart updates. The 

 German Federal Maritime and Hydrographic 

 Agency stations Hamburg/DDH and 

 Pinneberg/DDK were the secondary stations for 

 the ice chart transmission. In addition to these 

 sources, the ice chart was also available via 

 plain-paper facsimile, email on demand, and 

 the World Wide Web. 



Bulletin updates were delivered over the 

 Inmarsat-C SafetyNET via the Atlantic East 

 and West satellites. U.S. Coast Guard 

 CAMSLANT/NMF and Canadian Coast Guard 

 Marine Communications and Traffic Service 

 St. Anthony/VCM transmitted bulletin updates 

 via radio. Finally, like ice chart updates, 

 bulletin updates were also available via the 

 World Wide Web. 



Historical Perspective 



To compare ice years in a historical 

 perspective, IIP uses two different 

 measurements. The first is the length of time in 

 days when daily products were issued during a 

 given Ice Season (Figure 5). The second is the 

 number of icebergs crossing south of 48°N 

 (Figure 6). This measurement includes both 

 icebergs initially detected south of 48°N and
