There have been major improvements in instrumentation, field survey design and data
inversion techniques for the geoelectrical method over the past 25 years. Multi-electrode …

An accurate assessment of the physical states of the Earth system is an essential component
of many scientific, societal, and economical considerations. These assessments are …

Conventional geophysical inversion techniques suffer from several limitations including
computational cost, nonlinearity, non-uniqueness and dimensionality of the inverse problem …

Abstract 3D inversions of magnetotelluric data are now almost standard, with computational
power now allowing an inversion to be performed in a matter of days (or hours) rather than …

In controlled-source electromagnetic (CSEM) inversion with conventional regularization, the
reconstructed conductivity image is usually blurry and only has limited resolution. To …

The footprint of a mineral system is potentially detectable at a range of scales and
lithospheric depths, reflecting the size and distribution of its components. Magnetotellurics is …

The magnetotelluric (MT) survey of the Sabalan geothermal zone, which includes 22
stations along three traverse profiles across the main prospect zone, was conducted in …

The supervised descent method (SDM) is applied to 2D magnetotellurics (MT) data
inversion. SDM contains offline training and online prediction. The training set is composed …

Bayesian inversion of electromagnetic data produces crucial uncertainty information on
inferred subsurface resistivity. Due to their high computational cost, however, Bayesian …

Probabilistic inversion methods based on Markov chain Monte Carlo (MCMC) simulation are
well suited to quantify parameter and model uncertainty of nonlinear inverse problems. Yet …
