Drones Give Researchers Spectacular Footage In Whale Time

It’s common for kids to do headstands and blow bubbles. But whales? Marine researchers are seeing these creatures in a different light thanks to unmanned aerial systems, better known as drones. KLCC’s Brian Bull reports.

Oregon State University scientists have used drone-mounted cameras to capture the more curious antics of gray whales, which includes swimming upside down or snapping their jaws.

Leigh Torres is a principal investigator with OSU’s Marine Mammal Institute.

“These whales tend to do a lot of headstands," Torres tells KLCC.  "To get into crevices or into the sediments and feed that way. 

"Also, they seem to release strings of bubbles, so all of these behaviors are ways that they’re feeding that we didn’t quite know that they did before.”

Torres says drone footage gives researchers venues they can’t get while sitting in a boat. And it’s less intrusive.

“We keep the drone far enough away, that we’re pretty sure that the whales aren’t hearing it or really knowing it’s above them.

“Normally from our boats, we only are able to see the whales when they surface.  So that’s a very small percentage of their lives...10 percent or less," adds Torres. 

As whales spend the rest of the time underwater, researchers can observe them longer with the drone as long as the water clarity is decent.

Results of OSU’s drone-whale research is in the latest issue of Frontiers in Marine Science.
