本文首先介绍了海洋MT的特点、方法原理和正演模拟实现过程,并通过模型试验和中国东海北部DH剖面大地电磁场的二维正演模拟计算以及所做的结果分析,阐明了海洋MT在海洋资源勘探领域以及分辨洋底地壳地质属性的能力,最后对海洋MT的应用前景进行了探讨和展望。

The paper first introduced the forward modeling procedure by the way of the explanation of the characteristics and principles of oceanic MT. Then, it illustrated the abilities that the oceanic MT has for ocean resources as well as for the geological attribute identification of oceanic floor crust, based on the analyses of the models test and the 2D forward modeling of DH profile in the north of East Sea of China. The paper also gave a discussion on the development of oceanic MT as the conclusion.
