摘    要:当前海洋磁力探测中为了消除或减小地磁日变化的影响,必须设立地磁日变观测站(简称日变站)测量磁场变化,提供日变校正资料。依据多年工作经验,对作为基站使用的G882磁力仪和Sentinel磁力仪在工作原理、仪器技术性能、工作使用体会等方面进行综合比较分析。结果表明,Sentinel磁力仪比G882磁力仪对环境适应性更好、灵活性更强,进行日变观测时应优先选用。

关 键 词:海洋磁力探测  日变观测  磁力仪

Abstract:Established geomagnetic base station nearby or in the survey area can provide appropriate diurnal variation correc- tion. It aimed to finish or decrease geomagnetic diurnal influence in marine magnetic survey. G882 and Sentinel magnetometer are used as base station for many years. On the basis of that, the two type instruments have comparative analyzed in many aspects such as the operating principle, instrument technology performance, using the experience work, etc. The results show that, Sentinel magnetometer should be first chosen in diurnal observation, because it is more suitable to working situation and its flexibility is stronger.
Keywords:marine magnetic survey  diurnal observation  magnetometer
