Acoustic survey

An acoustic survey uses sound waves to study underwater environments. Specialized equipment sends out sonar signals that travel through the water and bounce back when they hit objects like fish, the seabed, or submerged structures. By analyzing these returning signals, scientists can determine the location, size, and quantity of underwater features or creatures. This method is non-intrusive and efficient, providing vital data for activities like marine research, resource assessment, and environmental monitoring. It’s similar to using echolocation—like how bats navigate—adapted for studying the complex underwater world.
