A new study suggests that certain species of sub-Arctic whales are increasingly making their way through the Bering Strait towards Arctic waters, raising questions about what may be causing these species to expand their territory.

Researchers used underwater microphones to track the whales as they made their way through the strait towards the Chukchi Sea.

Besides Arctic beluga and bowhead whales, the microphones picked up large numbers of sub-Arctic killer whales and humpback whales swimming to the Arctic.

Here’s some of what the researchers heard:

Those involved in the U.S. – Russia study say their findings raise interesting questions about what is actually driving the sub-Arctic whales into the Arctic and if they could one day become competition for Arctic bowhead and beluga whales.
