Ship noise boosts stress in whales, 9/11 reveals: Study

Because they live, feed and breed so close to shore, critically endangered North Atlantic whales are already threatened by ship collisions and fishing gear entanglements, two leading causes of death among large cetaceans.“Acoustic pollution from anthropogenic sources presents a less visible but pervasive disturbance to these coastal-dwelling whales that may have negative consequences for population viability,” the study concludes.
