sonar buoy

A sonar buoy is a floating device used primarily in maritime operations to detect and analyze underwater sounds. It works by emitting sound waves, which bounce off objects like submarines or schools of fish, and then listening for the returning echoes. The data collected helps in navigation, marine research, and military applications. Sonar buoys can operate autonomously and transmit information back to ships or aircraft, aiding in environmental monitoring and defense measures. They play a crucial role in understanding oceanic conditions and ensuring safety in marine environments.
