Abstract The submersible buoy with turbulence instrument is an effective and a long-term observation platform of the turbulence in deep sea and plays an important role in marine scientific research. The current development of turbulence instrument at home and abroad and shear probe measurement principle were briefly introduced, according to the measurement data with the turbulence instrument submersible buoy. The factors affecting the measurement results of flow vibration instrument were analyzed. The methods to reduce noise pollution were discussed. According to the noise caused by the vibration of cable transmission, the method of application of low temperature water damping material was proposed. The damping experiment data analysis indicated that adding damping material can effectively reduce the influence of vibration on the measurement accuracy.
