Sonar system responsible for causing whales to strand themselves
mardi 15 octobre 2013 à 14:00A sonar system used to map the ocean floor seems responsible for causing 100 whales to strand themselves on Madagascar.
Some sonar systems produce extremely loud sound that can deafen whales or drive them frantic to escape. The sound does not penetrate the air, so I suspect that stranding themselves is a way to escape the sound. However, when whales strand themselves, it is usually fatal.
