Can a submarine sonar kill you?

Unfortunately for many whales, dolphins and other marine life, the use of underwater sonar (short for sound navigation and ranging) can lead to injury and even death. … These sound waves can travel for hundreds of miles under water, and can retain an intensity of 140 decibels as far as 300 miles from their source.

How deep do modern submarines go?

How Deep Can You Go in a Submarine? That’s classified. What the Navy can tell you is that their submarines can submerge deeper than 800 feet. But they don’t go as deep as the research subs that explore the seafloor.

Do submarines ever use active sonar?

Most subs have two types of sonar: active and passive. … If the ping bounces back, that means it hit an object—like a whale, a ship, or another submarine. But stealth subs often avoid active sonar, since the ping could give away their location. Instead, they use passive sonar, which merely detects sounds.

Does submarine sonar kill whales?

The US Navy has admitted concerns over sonar’s effects on marine mammals, although actual evidence for harm has been in short supply. But military-sponsored tests now suggest that low levels of sonar, which do not cause direct damage to whales, could still cause harm by triggering behavioural changes.

Do submarines ever run into whales?

It happens on rare occasions. Whales make sounds that can be heard by the submarine sonar. Submarines usually try to avoid the whales, but on the rare occasions that a collision occurs, it is the whale that suffers the worst of it.
