Buoy

A buoy is a floating device anchored to the seabed, used for various purposes such as marking locations, guiding navigation, or providing information to mariners. They can be equipped with lights, sensors, or signals to indicate hazards, specific routes, or environmental conditions. Buoys are essential for maritime safety, helping ships avoid dangerous areas, find their way, or monitor ocean data like weather or water quality. They come in different types—such as navigation buoys, weather buoys, and research buoys—each tailored for specific functions in marine environments.
