Abstract Wave and wind effect marine magnetic survey data in the vertical space. This is because the two-dimensional Taylor polynomial doesn’t include the influence of the change of height in establishing the regional marine geomagnetic field model. In order to solve this problem, a three-dimensional Taylor polynomial is put forward to construct the regional marine geomagnetic field model. By simulating a certain area of underwater sphere magnetic field and ship-borne magnetic survey data, this paper analyzes choosing the truncation order of the two models, the difference between the complete polynomial expansion and the classical expansion methods, and the boundary effect of the two methods. The results show that: the three-dimensional Taylor polynomial method can reflect the distribution of marine magnetic anomalies better and overcomes the boundary effects in considering the height changes.
