A video filmed by student Kathryn Purdon on board the CCGS Admundson shows three polar bears adrift in waters far from ice. They were "curious about our trace metal sampling system cable," the caption of the YouTube video says of the mother bear and her two adolescent cubs. (Traces of metal in ocean water is an impact of climate change.)
It wasn't totally clear what, exactly, drew the polar bears close - perhaps they were tired of swimming and were hoping to climb aboard, or perhaps they were looking for food. Or maybe it was simply a whimsical curiosity.
Whatever it was, the scientists, who are studying the effects of climate change on the ocean, had to be firm with the animals they're ultimately trying to save. "Go away!" they shouted, nervous about possible damage to their expensive research equipment.
