Oceans - Noise Pollution
The noise pollution produced by ships and marine construction projects in the Gulf of Maine is drowning out the sounds that Atlantic cod and haddock need to communicate with each other, according to a new study.
The U.S. environment agency NOAA says this is altering the behavior, feeding, mating and socializing of the commercially important fish.
The study concludes that since the fish make sounds to attract mates and listen for predators, not hearing those signals could threaten their breeding success and survival.
