From: Numerical studies of geomagnetically induced electric field on seafloor and near coastal zones incorporated with heterogeneous conductivity distributions

Fig. 3

Top: plane view and cross section of the 3-D conductivity model. Others: plane view of total amplitude of magnetic field (three contour maps at the left) and electric field (three at the right) at a frequency of 0.001 Hz. Double arrows indicate the polarization of source magnetic field and the induced electric field far from the coastline. Three horizontal planes (0, 1500, and 3300 m depth, respectively) of magnetic and electric fields are shown, which are normalized by the amplitude of source magnetic field. White lines indicate the boundary between seawater and ground at each depth. WD water depth
