Robust magnetotelluric response function estimators are now in standard use in
electromagnetic induction research. Properly devised and applied, these have the ability to …

The polar regions are host to fundamental unresolved challenges in Earth studies. The
nature of these regions necessitates the use of geophysics to address these issues, with …

The Slave craton in northwestern Canada, a relatively small Archean craton (600× 400 km),
is ideal as a natural laboratory for investigating the formation and evolution of Mesoarchean …

Publisher Summary This chapter focuses on the simultaneous arrays of electromagnetic
(EM) soundings of the Earth using natural fields, systems of their relevant transfer operators …

Many geophysical regression problems require the analysis of large (more than 104 values)
data sets, and, because the data may represent mixtures of concurrent natural processes …

The simultaneous nature of array data can be exploitedin electromagnetic induction
studiesfor three general purposes. First, one or more reference sites can be usedto reduce …

A technique for constructing a system of transfer operators is proposed for array data of
simultaneous electromagnetic (EM) soundings; the technique is adapted to the high-latitude …

Nonstationarity in electromagnetic data affects the computation of Fourier spectra and
therefore the traditional estimation of the magnetotelluric (MT) transfer functions (TF). We …

A major step in processing magnetotelluric (MT) data is the calculation of an impedance
tensor as function of frequency from recorded time-varying electromagnetic fields. Common …

The simultaneous implementation (complete or hybrid) of electromagnetic sounding arrays
with natural fields opens important possibilities to improve the data accuracy in the presence …
