An ocean magnetometer detecting near seafloor can reveal more information for geologists and geophysics. A new design of Ocean Bottom Magnetometer was proposed in the paper. The sensor error compensation and circuit design was given in detail. The data logger was elaborately designed for data acquisition, data storage and data readout. The first sea trial for this system was described and a data analysis was given as well. Some preliminary conclusions were obtained and some prospects were given for further research.
