Tracking Narwhals in Greenland 2006-2007

In the frigid waters off the coast of Greenland scientists are getting valuable data from narwhals - the most ice loving whales in the world. Narwhals, beluga and bowhead whales, which you can hear in the background, make their homes in the Arctic. There are about 100,000 narwhals in the world, and the vast majority of them - about 50,000 to 70,000 - live in the Arctic waters of Greenland.
