What stages have China marine buoys gone through?

In the past 30 years, the development of China's marine buoys has gone through the development process of primary stage, climax stage and maintenance and improvement stage.

Ocean buoy is an automatic observation station for marine hydrology, water quality and meteorology, which is mainly composed of observation buoys anchored at sea. Meteorological data such as marine hydrology, water quality and water quality can be collected continuously for a long time according to the specified requirements, especially the data of bad weather and sea conditions that are difficult for survey ships to collect.

Ocean buoy is a modern ocean observation facility. It has the ability to collect marine environmental data stably and reliably all day, and can realize automatic collection, automatic labeling and automatic transmission of data. Ocean buoys, satellites, airplanes, survey ships, submersibles and acoustic detection equipment together constitute a modern marine environmental monitoring system.

The role of ocean buoys:

Ocean buoy is an important tool for measuring hydrometeorological elements such as wave height, ocean current, sea temperature, tidal level, wind speed and air pressure. Mastering these data will bring more convenience to people.

For example, if you know the direction of ocean current, you can sail as smoothly as possible, saving navigation time and energy consumption; Knowing the abnormal rise of tide level can prevent emergencies in time and minimize losses when disasters occur.

Marine buoys are also widely used in marine survey and marine environment monitoring, to quantitatively grasp the changing law of marine environment, so as to make more accurate marine environment prediction and serve military, navigation, fishery, port engineering and marine development.
