New Data Sources 



In 2006 CIS included in the database 362 satellite radar targets into the database north of 

 50° N. CIS and IIP are participating as end users in the Polar View Program, which is supported 

 by the European Space Agency and the European Commission with participation by the Canadian 

 Space Agency. C-CORE, the team's prime contractor, provides iceberg-sighting information 

 determined from satellite-based radar images. Although 362 targets comprise only a small 

 fraction of the number of observations in 2006, it is clearly a category that will grow as the 

 technology improves. IIP has not started to enter reports from the radar satellites into the 

 database. 



Conclusions 



The following are the major changes due to the synchronization: 



1. Area of Coverage: The synchronized database encompasses a much larger area than in 

 previous years. 



2. Iceberg Population: The database will be a better representation of the iceberg population 

 near Newfoundland's northern peninsula and the Strait of Belle Isle because it provides 

 more detail. 



3. Radar Targets: The area between 50° N and 52° N will have more radar targets because of 

 CIS' policy of entering them into the model. 



4. Satellite Usage: CIS has begun to enter into the database targets detected by satellites, 

 while IIP has not. This is a practice that will become more common as satellite radar 

 observations become more reliable. 



5. Iceberg Pedigree: Synchronization of the database allows IIP to maintain a pedigree of an 

 iceberg regardless of where it was seen. In previous years, icebergs entered into the model 

 by CIS north of 52°N were entered into the IIP database with the source labeled only as a 

 target produced by the CIS database. The original information on the reporting source and 

 the iceberg's size and shape was not carried into HP's database.
