Fig. 5From: Approximate treatment of seafloor topographic effects in three-dimensional marine magnetotelluric inversion∣E∣ and ∣H∣ normalized by seafloor values versus depth for T = 3000. Open circles indicate the values of the EM field components calculated on the top/bottom surfaces of the blocks. Solid circles indicate the values of the EM field components on the seafloor, which is just bounded by the block surface when using mesh A. Diamonds and crosses indicate the values of the EM field components on the seafloor calculated by extrapolation and interpolation, respectively, using mesh B.Back to article page
