What is the impact on marine life exposed to this sonar?
Aquatic animals are very vulnerable to high sound levels especially those with air filled lungs and swim bladders. Whales and dolphins are especially vulnerable because they are acoustic animals. Powerful underwater sounds can kill them by causing internal bleeding from ruptured tissues, or deafness. If a mammal’s hearing is impaired this causes difficulties in navigation, feeding, communication, and mating. So, therefore, a deaf whale is a dead whale.
