摘要: 海底热流探针是一种高分辨、高精度的温度测量设备,定期对其进行温度校验是保证其测量数据准确性的一个必要环节. 鉴于海底热流探针的尺寸和其他技术指标等特点,传统的温度校验方式无法适用于广州海洋地质调查局自主研发的温度测量仪. 针对该问题,设计了一种基于美国海鸟SBE 917plus型温盐深( CTD)测量仪的适用于深海测温设备的温度校验方法,通过海上试验确定其可以适用于海底热流探针的校验,为用常规方法无法进行校验的深海测温设备提供了新的校验方法. 该方法也可用于其他的深海测温设备的温度校验工作.Abstract: The submarine heat flow probe is a high-resolution, high-precision temperature measurement equipment, temperature cali-bration is carried out periodically which is an essential part to ensure the accuracy of the measurement data. The traditional temperature calibration is not applicable to Guangzhou Marine Geological Survey temperature gradient probe because of the size and other technical indicators of the submarine heat flow probes, design a calibration method based on US Seabird SBE 917plus type conductivity-tempera-ture-depth system ( CTD) which is suitable for deep-sea temperature measurement equipment. This method can be applied to check sea-floor heat flow probe by sea trials, which provides a new checking method while the conventional methods can not be verified in the deep sea temperature measurement equipment. This method achieved good results in the offshore applications survey and broaden its ap-plications, which can also be used to temperature calibration for other deep-sea temperature measurement devices.
