Ocean Noise

The racket of human activity beneath the ocean surface is drowning out the natural noises made by marine creatures, which researchers say is as harmful as overfishing, pollution and climate change.

A University of Exeter team made the conclusion after reviewing more than 500 studies on marine noise. The review says while military sonar and oil exploration blasts are obvious sources of distress and deafness in the ocean, noise from shipping has increased by 32 times in the past 50 years. The study says the din of offshore wind farms, bottom trawling and other sources are drowning out the calls many species use to communicate, spawn and migrate.
