sonar buoys

Sonar buoys are devices deployed in water to detect and analyze sounds, typically used by naval forces for underwater surveillance. These buoys transmit sound waves and listen for echoes that bounce off submarines, ships, or marine life. They can be deployed from aircraft or ships and are valuable for monitoring submarine activity, conducting oceanographic research, or tracking marine wildlife. The data collected helps in navigation, maritime security, and environmental studies, making sonar buoys essential tools for modern ocean exploration and defense.
