Abstract

A new type of ocean bottom magnetometer (OBM) for investigations of the basic magnetic field is developed.The data of marine geomagnetic field could not only improve the complete basic model of the geomagnetic field with high spatial and temporal resolution, but also satisfy the global geophysical field research needs. The developed OBM is according to the philosophy of design that it should be high sensitivity, low power consumption, light in weight, robust enough against mechanical shocks, reliability for long-term observations. So the developed prototype includes a compact spherical coil system and Overhauser effect sensor for measuring the total strength of the geomagnetic field and the vectors of strength, Delta inclination - Delta declination (this kind instrument called dIdD), meanwhile we also improve the performances of tri-axial fluxgate sensor for geomagnetic vector filed measurement (H,Z and D components). The advantages of this method are be calibrated by each other sensor and get the whole elements of basic geomagnetic field. Then we had carried out comparative measuring test in the Jinghai geomagnetic observatory. As a result, the developed OBM shows better performance in the accuracy of magnetic field and angle less than 0.2nT, 0.004° respectively.
