Abstract：Based on the condition of homogeneous and horizontally layered medium and on the precondition of hypothesis that the horizontal component of total magnetic field on the ground and resistivity of medium are irrelative to variation of depth,using currently-used MT apparatus on the ground,laying out magnetic channels on the ground and electric channels on the shallow sea to carry out synchronous acquisition, the MT survey on the shallow sea could be realized in combination with the practical situation on the shallow sea and adopting relative technical measure.The different intervals of electrical and magnetic channels are also systematically tested.The different tests are carried out as follows: acquisitions at different depths and tests for surveying in far-referential channel, meanwhile, using a sea-land MT section survey to gain test results and examine the method,which proved the feasibility of the method.
