The Canadian Ice Service is tracking icebergs to monitor and predict drifting patterns in the western Arctic for the first time, according to one of its ice analysts. Last week, the organization — a branch of Environment and Climate Change Canada (ECCC) — dropped beacons from a Hercules aircraft onto icebergs in the Beaufort Sea. Adrienne White, an ice analyst with the Canadian Ice Service, said that while it's common practice to track icebergs in the eastern Arctic, they have never before deployed sensors in this area.
