    摘要:

    海洋生物化学要素是海洋环境与生态监测的重要对象。传统的监测方法多基于人工操作,需 要使用化学试剂,不仅测量时间长,而且无法及时准确反映海水的当前状态。该文基于光学传感的方 法,研究无需化学试剂的海洋叶绿素 a、化学需氧量(COD)、生化需氧量(BOD)原位传感器和水下浮 游生物成像仪,并基于浮标平台在近海开展了海洋原位测量实验和示范。在海试过程中,通过采用环 境友好的生物涂料和机械刷设计,克服了生物附着对传感器连续工作的影响,实现了传感器连续原位 工作 6 个月以上,实验结果准确反映了海水的真实状态。

    Abstract:

    Biochemical indices are important measurands in marine environmental and ecological monitoring. Traditional monitoring methods of biochemical indices usually use chemical reagents and the operation is also time-consumed. Moreover, after a long measurement time, the results cannot accurately reflect the real status of seawater. In this work, four in-situ sensors are investigated based on the optical sensing principles, i.e. the chlorophyll a, chemical oxygen demand (COD), biochemical oxygen demand (BOD), and the underwater plankton imager. The development of the instrument prototypes and buoy-based in-situ trial experiments have been completed and described. During the sea trial, the environment-friendly antifouling paint and mechanical wipers have successfully overcome the biological fouling issues to the sensors, which have been kept operation underwater for more than six months. From the trial experiments, we have collected a large amount of real seawater data and maintenance experience of the equipment. The buoy trial results also reflected the true conditions of the seawater.
