The article by Cory Mathews, “Satellite tracking of a killer whale (Orcinus orca) in the eastern Canadian Arctic documents ice avoidance and rapid, long- distance movement into the North Atlantic” tracks the 90-day explorations of two killer whales. According to the Mathews, “In August 2009, we deployed satellite transmitters onto killer whales in Admiralty Inlet, Baffin Island, to (1) determine seasonal movements in the eastern Canadian Arctic and (2) distribution in the North Atlantic.” They did this by shooting titanium darts (tags) that would penetrate the dermal tissue upon contact. These devices would send 300 transmissions each day via Polar- orbiting satellites. The results showed that the killer whales would travel long- distance movement
