Deep Electromagnetics and Magnetotellurics
Ute Weckmann
This course will teach you about the different types of electromagnetic techniques (like Magnetotellurics) that can be used to study the physical properties of the Earth's depths, like its electrical conductivity. These techniques are special because they have almost no impact on the environment, which makes them perfect for places like the Antarctic or nature reserves. The physical parameter measured by this method is more sensitive to water content and properties, melts, etc., than e.g. densities or seismic properties. We will show you how the method works and what the results are, using recent research examples.
The aim of this lecture is to:
• understand the electromagnetic processes in the subsurface,
• know the challenges of getting data in the field, different instrument and sensor types, and processing of data afterwards,
• 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, offshore and onshore 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?
• How does MT help in subglacial imaging and monitoring?
• And, of course, your own questions.
And very important: hands-on codes and instruments.
