Current situation and trend of marine data buoy and monitoring network technology of China.

Marine data buoy can provide a long-term, continuous, real-time, reliable data of ocean observation in a variety of complex marine environment. It is one of the most reliable, most effective and important means of ocean monitoring technology. In this paper, the classification, main theory and technology system of marine data buoy are summarized. The typical technological breakthrough of the development of marine data buoy in recent years is summarized. The composition and application of marine monitoring network in China was introduced, and the gap between the technology of China's marine data buoy and the international advanced countries is compared. Combined on the situation and demand of China's current situation and needs, the development trend of marine data buoy and buoy monitoring network are expected. [ABSTRACT FROM AUTHOR]
