APPLICATION OF OPTICAL FIBER TEMPERATURE AND PRESSURE SENSOR IN PHYSICAL OCEANOGRAPHY

Fiber optic sensor technology has been applied in civil engineering, aerospace, petrochemical and other fields, and increasingly sophisticated sensing technology in the temperature sensor, pressure sensor and flow velocity sensor. Fiber optic sensor has plenty advantages, such as proper insulation, easy to reuse, long distance transmission and so on, so it will have great potential in the field of physical oceanography. With the support of WPOS, the research group has developed fiber temperature, pressure sensor and the system telemetry aspects of practice application in marine ranch, which is the innovation of application of fiber temperature chain in marine farming. This provides technical support for modern marine ranch. Our group developed a ship towing temperature pressure chain system, which has been deployed in the Yellow Sea and the South China Sea cruises as rapid and efficient tests, the underwater temperature profile was obtained in real-time, continuous and in situ, the field temperature measurement test was applied for the first time. It provides a new means of rapid and high spatial and temporal resolution measurements for physical oceanography research, which will be beneficial to the physical oceanography and marine instruments and equipment research development level, playing a certain guiding role.
