Researchers were out on the Southern Beaufort Sea in Canada when a family of curious polar bears came swimming along.

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.
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.
