This workshop is suitable for geophysicists/geologists/engineers interested in ground based and airborne TEM surveys for groundwater mapping and students/staff at academic institutions involved in research on the TEM method, having a basic knowledge of geophysical survey methods.

Level: Beginner/Intermediate

The electromagnetic (EM) method is widely used for hydrological, environmental, engineering and mining surveys to map the subsurface resistivity. In this workshop, we will cover the basics of the TEM method and go through the steps from processing and inversion of TEM data examples to visualization of model results.

There will be hands-on exercises where we will go through processing, 1D inversion and visualization of results in sections, 3D viewer and GIS interface. If there is time, there will be a walkthrough of lateral (2D constrained) and spatial (3D constrained) inversions of TEM data.

We will use data acquired by the WalkTEM and tTEM instrument and the software packages SPIA and Aarhus Workbench. Results from airborne data will also be presented. At all times, the participants will be able to follow the workflow through a shared screen and hence ask the questions they might have to the software.

Course participants will be given a free, time-limited license to work with data before and/or after the course. Hands-on exercises at the workshops will be sent to participants along with license information before the course. For hands-on exercises, please bring your own laptop.
