Beluga whales are highly vocal, acoustically sensitive cetaceans facing increasing noise pollution from Arctic shipping and industrial activity that interferes with their communication and navigation.
For highly vocal, social animals like belugas, noise pollution is not merely an annoyance but a fundamental disruption to core life functions. Communication for mother-calf coordination, group cohesion, and foraging coordination all depend on acoustic signals that industrial noise can mask or obscure. Chronic noise exposure causes elevated stress hormones and habitat displacement in beluga populations. The opening of Arctic shipping routes to year-round navigation is placing belugas at the intersection of multiple stressors — noise, vessel strikes, and climate change — simultaneously. The Cook Inlet population, critically endangered, faces extinction without dramatic reduction in anthropogenic disturbance.
