Buoy

ocean · navigation · safety

Floating helpers. Buoys are devices that float on the water and stay in one spot by being anchored to the ocean floor with heavy chains or cables. They mark safe paths for ships and warn sailors about danger zones like rocks or shallow areas.

Drifting scientists. Some buoys aren't anchored at all and drift wherever ocean currents push them. These roaming buoys collect important data about water temperature, waves, and weather as they travel across the sea.

Different designs. Buoys come in many shapes and sizes, from big bright cylinders to smaller cone-shaped markers. Each type is designed for a different job, whether it's marking a navigation route, measuring storms, or showing where fishing nets are located.

Lights and sounds. Many buoys have bright lights that shine at night to help ships see them, and some even make honking sounds or ring bells in fog so captains know exactly where they are.

Ocean information. Modern buoys act like floating laboratories, sending back real-time information about ocean conditions to weather centers and scientists who study climate and storms.
