Marine Animal Welfare

Marine Mammal Acoustic Ecology Welfare

Noise pollution from shipping, sonar, and industrial activities disrupts cetacean acoustic ecology causing welfare harm through communication interference and stress.

Key Facts

Shipping noise has increased by 3 dB per decade over the past 50 years in major shipping lanes
Low-frequency shipping noise overlaps with baleen whale communication frequencies
Military sonar has been linked to strandings of beaked whales through behavioral disruption
Speed reduction and route optimization can reduce shipping noise substantially
EU Marine Strategy Framework Directive includes underwater noise as a quality descriptor

Welfare Considerations

Individual cetaceans experiencing chronic acoustic pollution cannot communicate, navigate, or find prey normally. The welfare impact of chronic noise pollution on highly acoustic species is substantial and underappreciated relative to acute noise events like sonar.

What You Can Do

Support campaigns for shipping speed reduction in whale-rich areas
Advocate for mandatory quiet ship certification in major shipping lines
