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

This study presents results of mapping three-dimensional (3-D) variations of the electrical
conductivity in depths ranging from 400 to 1200 km using 6 years of magnetic data from the …

In this study, we present a tool to simultaneously invert multi‐source magnetic transfer
functions (TFs), including tippers, solar global‐to‐local TFs originating from the signals due …

There is significant interest in constraining mantle conductivity beneath oceans. One data
source to probe oceanic mantle conductivity is magnetic fields measured at island …

Most of the existing 3-D electromagnetic (EM) modelling solvers based on the integral
equation (IE) method exploit fast Fourier transform (FFT) to accelerate the matrix–vector …

The diversity of magnetic field information obtained in marine geomagnetic measurements is
of great relevance to defining detailed features of the targets. In this article, a solution …

Time-varying magnetic signals measured by geomagnetic observatories and satellites carry
information about the Earth's deep electrical conductivity structure and external current …

In the past three decades, an immense amount of magnetic field data (with periods of
measurements from months to years) has been collected worldwide, either inland or at the …

Magnetotelluric (MT) and magnetovariational (MV) sounding are two principal geophysical
methods used to determine the electrical structure of the earth using natural electromagnetic …

We conducted a magnetovariational field investigation at Lampedusa island (Italy), in the
proximity to the geomagnetic observatory of Lampedusa. Data were collected from March 19 …
