This expert report describes the importance of sound to killer whales; it is as important to whales as vision is to humans. As such, there are serious concerns for even more noise in their critical habitat. Southern resident killer whales produce and listen to sounds in order to establish and maintain critical life functions: to navigate, find and select mates, maintain their social network, and locate and capture prey (especially Chinook salmon). The existing level of noise has already degraded critical habitat and studies suggest it has reduced the feeding efficiency of these whales. The Trans Mountain Project will increase noise levels with adverse affects to southern resident killer whales.
