海洋垂直剖面水温实时监测浮标系统研制与应用

为了实时、连续地监测獐子岛海洋牧场养殖区域不同深度的温度状况,为海洋牧场构建和运行提供数据支持,项目组自行研制了海洋垂直剖面水温实时监测浮标系统,可以在水深≤50 m、风速≤60m/s、波高≤15 m的环境下应用。该浮标系统主要包括水面浮标载体子系统和剖面链观测子系统两部分,浮标载体子系统提供了安全可靠的工作平台;而剖面链子系统上的不同位置挂有多个水下传感器,用于测量相应位置的海水温度。耐压试验、温度标定、室内拷机、现场比测、海上拷机的检定数据表明该系统无渗漏、误差小、数据接收率100%。海上运行18个月的结果同样表明,浮标系统运行稳定,数据采集和接收率高,浮标电压稳定。实践表明该浮标系统具有测温精度高、结构简单、使用方便的优点,具有广泛的应用前景。

Research and application of real-time monitoring buoy system for marine water temperatures of vertical profiles

The construction of marine ranches is an important shift from the practice of traditional fishing to modern fisheries and represents a movement away from the predatory exploitation of marine fishery resources to environment-friendly and sustainable practices. The construction of ecological environment monitoring systems is an important part of marine ranch construction. For real-time, continuous monitoring of temperature conditions at different depths of farming areas on the Zhangzidao Island marine ranch and to provide scientific data to support the construction and operation of the marine ranch, we have developed a real-time monitoring buoy system that can be used at a water depth of less than 50 m, at a wind speed of less than 60 m/s, and in wave heights of less than 15 m. The buoy system comprises a buoy carrier subsystem and a vertical observing subsystem. The carrier subsystem provides a safe and secure work platform, and sensors that are linked at different depths on the vertical observing subsystem are used to measure water temperature. Data obtained from a pressure test, thermostat calibration test, indoor simulation experiment, in-situ test, and field measurements have shown no leakage and small errors. However, most importantly, a data acceptance rate of 100% can be reached. Results from 18 months of actual marine application have shown that the buoy system is stable, the data acquisition and receiving rate is high, its voltage is stable, and it has a high temperature accuracy. In addition, it has a simple structure and is easily employed, thus has widespread application prospects.
