摘要
船载拖曳式多参数剖面测量系统是测量温度、深度、浊度、溶解氧、p H和叶绿素等多种海洋环境要素,提供海洋环境信息的重要观测设备。通过对2011年8月在渤海开展的CZT1-2型船载拖曳式多参数剖面测量系统比测试验,研究了该国产设备在渤海海区的适用效果。结果表明,传感器定点比测试验中,温度、盐度等数据的相关系数较好,而硝酸盐、磷酸盐、亚硝酸盐、硅酸盐和氨氮等营养盐的相对误差较大。在海试试验中,船载拖曳式多参数剖面测量系统经过了8 h试验,完成了预期的试验项目,拖体系统(含传感器)和甲板单元工作正常,具有良好的可靠性和环境适应性。本次海上比测试验为船载拖曳式多参数剖面测量系统进行改善、优化提供依据,为其产业化打下坚实的基础,并对海上试验提出了相应的改进建议。
The ship-borne drag multi-parameter profile measurement system is important observing equipment used to measure various marine environmental factors, including temperature, depth, turbidity, dissolved oxygen, pH and chlorophyll concentration, and to provide information on the marine environment. Based on the test for the CZT1-2 ship-borne multi-parameter drag profile system carried out in August 2011 in the Bohai Sea, this paper studies the applicable effect of domestic equipment in Bohai area. The results show that in the fixed-point comparison tests of sensors, correlation coefficients of temperature, salinity are relatively good, while the relative errors of nitrates, nitrites, phosphates, silicates and ammonia nitrogen are larger. In the sea test, a 8-h test for the ship-borne drag multi-parameter profile measurement system has completed the expected experimental programs, during which the drag system （including sensors） and the deck component work well and have good reliability and environmental adaptability, providing a sound basis for the improvement, optimization and industrialization of the system. This paper also puts forward corresponding suggestions for improving the tests at sea.
