What Is The Use Of Marine Buoys?

Marine buoys are generally divided into two parts, water and underwater. The water part is equipped with a variety of meteorological element sensors to measure meteorological elements such as wind speed, wind direction, air temperature, air pressure and temperature; the underwater part has a variety of hydrological element sensors to measure separately Marine hydrological elements such as waves, currents, tide levels, sea temperature and salinity.
 
The signals collected by various sensors are automatically processed by the instrument and sent out by the transmitter at regular intervals. After the ground receiving station processes the received signal, it obtains the information that people need. By mastering these materials, it will bring great convenience to people's production and life. If you know the direction of the current, you can go as far as possible when sailing; when you know the storm area, you can avoid bypassing when sailing; when you know the abnormal rise of the tide level, you can prepare for emergencies in time..
 
There are many types of marine buoys, including anchor type buoys and drift type buoys. The former includes meteorological data buoys, seawater quality monitoring buoys, wave buoys, etc.; the latter includes surface drifting buoys, neutral buoys, various small drifters, etc.
 

Coastal buoys are more commonly used anchoring buoys, which are suitable for short-term scientific experiments and environmental monitoring calculations, as well as for some seabed surveys. The bottom of the buoy, like a pendulum-type long arm, is fixed on the attachment. Coastal buoys can transmit the measured data to the satellite, which then transmits the signal to the ground receiving station and at the same time to the National Weather Service Network.
