This course introduces the diffusive electromagnetic techniques (magnetotellurics in all its varieties) that can be used to study the physical parameters of the Earth at great depths - in this case electrical conductivity.

The method is unique in that it has virtually no environmental impact and can therefore be used, for example, in the Antarctic or in nature reserves. The physical parameter imaged by this method is sensitive to water content and properties, melts, etc., much better than e.g. densities or seismic properties. We illustrate the method and its results with recent research examples.

This lecture's aim is to

    understand the electromagnetic processes in the subsurface,
    know the challenges of data acquisition in the field and subdequent data processing,
    assess the possibilities and limitations of the method,
    be able to interpret the data and inversion models obtained and
    apply them to the wide range of applications from industry to research, off- and on-shore measurements, sustainability research, resources, groundwater and tectonics ...

Ultimately, we also want to answer questions such as:

    when and why is a fault electrically conductive?
    which deposits show up as good or poor conductive anomalies?
    how does EM help in groundwater monitoring?
    ... [Your questions]

And very important: Hands on codes and instruments (practical).
