Abstract

The deep sea magnetic field detection is influenced by the environment of marine and the platform, the influence of the platform is mainly caused by platform rotation. The variation of the geomagnetic fields three-components caused by different directions of the platform rotation are compared by using the World Magnetic Model WMM2010.The results show that the changes of the three-components of the Earth's magnetic field caused by the platform rotation can not be ignored. So the measured results of the deep sea geomagnetic field detection should be compensated. The conclusion can be used for automatic correction of the deep sea magnetic field observation platform.
