TITANIC IIP’s Core Purpose: Promote safe navigation in the northwest Atlantic Ocean when danger of iceberg collision exists.

6 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 (NAO) Index

14 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

18 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).
