| Summary | Using magnetotelluric (MT) and geomagnetic deep sounding (GDS) methods, one can obtain the electrical structure beneath continents, including the lithosphere and asthenosphere. However, the lack of information on the conductivity structure beneath the ocean hinders a comprehensive understanding of the Earth's internal conductivity structure. In recent years, with the increase in the number of geomagnetic satellites launched by major countries such as China and those in Europe and the United States, the utilization of satellite magnetic field data for deep Earth conductivity structure studies has become increasingly popular. Notably, Magnetic field signals from tidal currents have proven effective in constraining the electrical structure of the lithosphere and asthenosphere beneath the ocean. Electromagnetic induced data contain information about the Earth's deep conductivity structure, which reflects the thermal state and compositional constituent of the Earth's matter. Those data can provide unique insights that are not obtainable through seismology. |
