Analysis of vertical space variation of marine magnetic field
海洋地磁场的垂直空间变化分析

Not all marine magnetic survey data can be reduced to a unified plane. In this paper, the vertical spatial variation of anomaly is analyzed by theory. Furthermore, the curved surface upward continuation method is adopted to analyse the vertical space variation of marine magnetic anomaly with two sets of real marine magnetic survey data. The law of vertical spatial variation with height is analyzed. At last, the reduction condition is brought out in this paper.
