Abstract:

The continuous real-time observations of multiple elements on the sea surface of seawater is the basis of marine investigation and research, especially in the case of polar icebreakers. Its often make repeated voyages over the Pacific Ocean, Indian Ocean, Southern Ocean, and Arctic Ocean, which is long-term and fixed. It is of great significance for marine investigation and research on many major scientific issues. The continuous real-time observation of multiple elements on the surface of seawater is the basis of marine investigation and research. Based on the surface water navigation observation system deployed on the R/V Xuelong, a surface water multielement real-time acquisition system, suitable for China’s modern polar scientific investigation, has been designed for the R/V Xuelong 2. The new system incorporates improved data accuracy, enhanced system integration, improved degree of automation equipment system aspects. After several polar field tests, the system was shown capable of meeting the needs of China’s ongoing polar investigations, providing stable operation, accurate observational data and low maintenance costs. The successful application of the new system will be of considerable benefit to field observation and survey campaigns conducted in the polar regions, and also provide reference significance for the construction of continuous observation systems for deployment on future scientific research ships.
