Underwater sound detection
Sonar equipment refers to devices that use sound waves to detect and locate objects underwater.
The technology sends out acoustic pulses and measures their echoes to determine distance, direction, and characteristics of submerged objects—submarines, fish, seafloor features.
The research vessel deployed sonar equipment to map the ocean floor.
Both military and civilian applications exist, from submarine detection to commercial fishing.
