Acoustic impact of tanker traffic on Southern Resident Killer Whales

Submitted by: Raincoast Conservation Foundation

The evidence:

Southern resident killer whales are endangered under Canada’s Species at Risk Act, and Trans Mountain’s tanker route transects critical habitat necessary for their survival and recovery. Killer whales use sound for critical life functions: navigation, finding mates, maintaining their social network, and hunting prey (especially Chinook salmon). Existing noise has already degraded critical habitat, and, studies suggest, reduced the feeding efficiency of these whales.  The Project will increase noise, with adverse effects for killer whales.
