TLDR
A new format for MT and related electromagnetic transfer function extensible markup language (EMTF XML) is developed, which is a novel, self-describing, searchable, and extensible way to store the data.Abstract:
Initial processing of magnetotelluric (MT) data collected at a site results in a small data file that defines the MT transfer functions (MT TFs) or variants at a discrete set of frequencies...read more

Bayesian inversion of magnetotelluric data considering dimensionality discrepancies
Hoël Seillé,Gerhard Visser +1 more
TL;DR: This work proposes a methodology to quantitatively compensate for the bias caused by the 1-D Earth assumption within a1-D trans-dimensional Markov chain Monte Carlo sampler using a dimensionality discrepancy error model derived by a machine learning algorithm trained on a set of synthetic 3-D conductivity training images.

Computational recipes for electromagnetic inverse problems
Gary D. Egbert,Anna Kelbert +1 more
TL;DR: In this paper, a general mathematical framework for Jacobian computations arising in electromagnetic (EM) geophysical inverse problems is developed, which is based on the discrete formulation of the forward problem and divides computations into components (data functionals, forward and adjoint solvers, model parameter mappings).

Robust estimation of geomagnetic transfer functions
Gary D. Egbert,John R. Booker +1 more
TL;DR: In this article, the authors show that all of the statistical assumptions usually used in estimating transfer functions for geomagnetic induction data fail at periods from 5 min to several hours at Geomagnetic mid-latitudes.

Crustal rheology of the Himalaya and Southern Tibet inferred from magnetotelluric data
TL;DR: In this article, magnetotelluric data from the Tibetan-Himalayan orogen from 77 degrees E to 92 degrees E was used to image subsurface electrical resistivity, interpreted as a partially molten layer.

TL;DR: Magnetotelluric exploration has shown that the middle and lower crust is anomalously conductive across most of the north-to-south width of the Tibetan plateau, suggesting that partial melt and/or aqueous fluids are widespread within the Tibetan crust.
