Habour porpoises change behaviour when exposed to noise from small boats
Recreational boating is increasingly popular, and noise from small boats may have strong impacts on the health of cetaceans. Although animals’ reactions to boat noise have been studied, this has not previously been done in controlled settings. Here, we investigated how noise from a small boat influe...

Summary: | Recreational boating is increasingly popular, and noise from small boats may have strong impacts on the health of cetaceans. Although animals’ reactions to boat noise have been studied, this has not previously been done in controlled settings. Here, we investigated how noise from a small boat influenced harbor porpoise (Phocoena phocoena) behavior. Observing porpoises with a drone, we collected their responses when passing animals at 10 and 20 knots. Porpoises started changing behavior when the boat was |
