The Ocean Is Too Loud For Whales And Dolphins
Sonar and noise from ships can harm marine mammals.By Ethan Weston | July 16, 2016
Our oceans are noisy. The movement of ships, pinging of sonar and whir of propellers are a near constant wherever man is.
And that has a big affect on ocean life, especially mammals like whales and dolphins that use sound to communicate, move around and locate food.
For one, man-made sonar disrupts whale behavior. A 2008 study found that some whale species stop "vocalizing and foraging for food" around sonar. And that can lead to starvation and death.
