As an effective and efficient geophysical tool, airborne EM (AEM) is specifically suitable for
the exploration in areas of high mountains, desert, swamp, and forest. With the development …

Geomagnetic disturbances cause perturbations in the Earth's magnetic field which, by the
principle of electromagnetic induction, in turn cause electric currents to flow in the Earth …

The Jacobian of the non-linear map** from model parameters to observations is a key
component in all gradient-based inversion methods, including variants on Gauss-Newton …

We describe implementation of a modular system of computer codes for inversion of
electromagnetic geophysical data, referred to as ModEM. The system is constructed with a …

Small amounts of water can significantly affect the physical properties of mantle materials,
including lowering of the solidus, and reducing effective viscosity and seismic velocity. The …

In the last few decades, the demand for three-dimensional (3-D) inversions for
magnetotelluric data has significantly driven the progress of 3-D codes. There are currently a …

We present a multi‐resolution finite‐element approach for three‐dimensional (3D)
electromagnetic (EM) induction modeling in spherical Earth. First, the secondary electric …

Geomagnetic data are widely used in earthquake prediction, mantle conductivity imaging,
and other fields. However, the problem of geomagnetic data being contaminated by cultural …

Despite exhibiting excellent inversion results for synthetic data in magnetotelluric (MT)
inversion, applying deep learning (DL) to directly inverting MT field data remains …
