Chasing Unicorns Canadian premiere on Oasis HD

The narwhal is the unicorn of the sea, a pale-colored porpoise found in Canadian Arctic and Greenlandic waters and rivers. These legendary animals have two teeth. In males, the more prominent tooth grows into a swordlike, spiral tusk up to 8.8 feet. The ivory tusk tooth grows right through the narwhal’s upper lip.. Females sometimes grow a small tusk of their own, but it does not become as prominent as the male’s. Now, a group of scientists, explorers and adventurers traces the narwhal’s path north to its summer home. Their mission is to capture a snapshot of the arctic ecosystem –for future generations to use as a benchmark. But the high arctic throws them one dangerous obstacle after another. To keep up with the migrating narwhal, they must navigate the thickest sea ice in generations. In the end, their journey leads them to the frozen edge of a changing world.
