“雪龙2”号表层海水多要素实时观测系统的设计与应用

Design and application of a surface water multielement real-time observation system for the R/V Xuelong 2

极地考察破冰船航线穿越太平洋、印度洋、南大洋和北冰洋在内的多个大洋,具有长期性和固定性,对于海洋调查研究及许多重大科学问题的研究具有重要意义。海水表层多要素的连续实时观测是海洋调查研究的基础,因此在“雪龙”号表层海水走航观测系统应用的基础上,“雪龙2”号结合国际前沿热点问题,从提高数据准确性、增强系统集成性、提高系统自动化程度等方面着手,设计了一套适合我国现代化极地科学考察的表层海水多要素实时采集系统。经数次极地考察实地检验,系统能较好地满足我国极地考察需求,且运行状态稳定、观测数据准确、维护成本较低。该系统的成功应用,对极区海洋现场观测调查具有重要意义,也对后续科学考察船的走航连续观测系统建设具有一定借鉴意义。

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.
