  2. Overview • Goals • Past 2007 deployments • Expected deployments in 2008. • IPY partnership IABP Annual Meeting, Toulouse

  3. Goals • Obtain real-time drift information to supplement radar (or visual) imagery used to created daily ice charts. • Monitor regional and local ice motion • Provides history of ice motion; • helps supplement various imagery sources used for daily and weekly ice charts. • Provides MSLP information for CMC / Ed. • Partner with other science work. • Verify drift model (Sea ice and Iceberg). IABP Annual Meeting, Toulouse

  4. 2007 deployments • 1 Calib for CHC (north of Resolute). • 2 Calibs in Nares Strait • 1 died after ~ 2 months • 1 still moving! • 1 Calib on the ice island (Ayles shelf) • Died during summer months (water puddle) • Split into 2 pieces in Sverdrup channel. • Re-started to beep in Sept after freeze up. IABP Annual Meeting, Toulouse

  5. 2008 deployments • 1 Calib on the 2nd piece of the Ayles island • Not expected to move until early August. • Might loose 1st piece again through summer months. • Should even consider identical problem with 2nd piece. • 2 Calibs for CHC tracking old ice with embedded temperature chain (1 failed). • 3 Calibs for Amundsen (IPY)…to be deployed in M’Clure Strait; CGDT did go up to M’Clure but deployed non-CIS buoys. • 4-6 Calibs for validating new ice drift model in Lancaster Sound… won’t happen due to NRI permission. • CIS provided funding for 2 ICEX buoys for White Trident project. IABP Annual Meeting, Toulouse
