More importantly, the EM induction method is generally sensitive to the conductivity beneath each observation site.
Geophysical methods, such as electromagnetic (EM) induction, offer an alternative, more robust, and less expensive approach to gather soil information.
Although electromagnetic (EM) induction data has shown potential in mapping ASS, few studies have been conducted to map the spatial distribution of pH at different depths.
The EM induction method provided a quick and cost-effective reconnaissance technique for identifying large-scale lateral variation in lithology, and for siting resistivity profiles and further boreholes.
A sequence of glacial and alluvial deposits overlying the Cretaceous Chalk in Eastern England was characterised using two geophysical techniques: electrical resistivity imaging and electromagnetic (EM) induction.
Two of the most popularly used sources of ancillary data are the proximally sensing electromagnetic (EM) induction instruments and remotely sensed digital elevation model data (DEM).
Electromagnetic (EM) induction sounding with natural sources contributes to our knowledge of the composition, temperature, and presence of fluids in the Earth's interior.
The method of electromagnetic (EM) induction has long been a standard geophysical tool used to study the electrical conductivity of the Earth (Lahiri and Price, 1939; Banks, 1969).
Global 3-D electromagnetic (EM) induction studies can thus provide complementary information to global seismic tomography (e.g. Becker and Boschi, 2002; Romanowicz, 2003), which is used to ascertain the mantle's bulk mechanical properties.
To answer these questions, we use a barotropic tsunami model and a state-of-the-art 3-D EM induction code to simulate the electric and magnetic fields generated by the Indian Ocean Tsunami.
