IIPs Core Purpose Promote safe navigation in
the northwest Atlantic Ocean when danger of
iceberg collision exists.

Iceberg Season 2004

• As predicted by CIS Iceberg Season off to a
  slow start! (IIP has not officially opened its
  season yet!)
• Above normal temps (Jan) limited sea ice growth
• Winter storm track onshore winds
• Persistent Negative North Atlantic Oscillation

Satellite Imagery for Iceberg Detection
Identification

• C-CORE has developed Iceberg Detection Algorithm
  as part of Northern View Service Element of GMES
  
• Funded by ESA
• C-CORE used both RADARSAT ENVISAT images
• IIP End User - Iceberg Detection Reports
  delivered for each image using MANICE system

Iceberg Drift Model Validation

• Deployed Compact Air Launched Ice Beacon (CALIB)
  onto an ice island in May 2003
• Tracked for 13 days results show that berg drift
  was within error circles produced by Berg
  Analysis Prediction System (BAPS)
• Deploying more CALIBs in 2004!
• Working with Canadian Ice Service to validate new
  BAPS. (and synchronizing databases).
