NEWLY CALVED ICEBERGS JOB SECURITY ?

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).

19 Drift Track Iceberg Size: ~250 m x 100 m
