JOB SECURITY
?
5IIPs Core Purpose Promote safe navigation in
the northwest Atlantic Ocean when danger of
iceberg collision exists.
6Iceberg 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

14Satellite 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

18Iceberg 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).
