Many marine animals rely on their hearing for orientation, to find food and mates, and to defend themselves against predators. The noise produced by ship engines and propellers, sonar systems, and by seismic surveys for oil and gas exploration, not only interferes with the life of marine animals, but can also severely affect their vital organs. Reduced ship speed, the use of innovative quieter technologies and the creation of noise-free marine zones are needed to stop this deadly threat.
of noise pollution is achievable with a 20% reduction in ship speed.
Ocean noise pollution is an invisible and deadly menace to marine life, which needs to be urgently reduced to ensure it is bearable for marine animals populating our seas.Tobias Troll, Marine Policy Director, at Seas At Risk.
