They use Sonar to send sound waves to the bottom of the oceans.
Submarines have sonars.

A torpedo is a self-propelled underwater weapon with an explosive warhead. It can be launched by aircraft, ship, or submarine, against surface vessels or submarines. Torpedoes use monopropellants (e.g., Otto Fuel) as engine fuel, which has its own oxidizer, since there isn't any oxygen to sustain a combustion engine underwater otherwise.
Sonar, which stands for "sound navigation and ranging," is the method used to find objects underwater by emitting sound waves and measuring the time it takes for them to bounce back. This allows for the detection and location of underwater objects like shipwrecks, submarines, and marine life.

Sonar (Sound Navigation and Ranging) is a method that uses sound waves to find objects underwater. It works by emitting sound pulses and measuring the time it takes for the sound waves to bounce back, allowing for the detection of underwater objects such as submarines, ships, or marine life.
sonar is a device for detecting objects underwater by emitting sound waves and analyzing the echoes that bounce back. It is commonly used in navigation, fishing, and underwater mapping.
Naval submarines do not dive deep enough to go near underwater mountains. This is contrary to what you may have seen in the movies. They use sounding charts to determine the depth of the water in which they are navigating. They avoid such underwater objects. Research submarines use cameras and sonar, as well as charts, to guide them.
Submarines use echolocation to detect, locate, and avoid obstacles underwater, as well as to navigate their surroundings. By emitting sound waves and analyzing the echoes that bounce off objects, submarines can map their environment in conditions where visual navigation is limited or impossible.
They are called submarines
