The geophysical method used in this project is the TEM (Transverse Electromagnetic Mode). We will use the tTEM tool developed by the hydrogeophysics group in Aarhus (Denmark). Details are on the page: hgg.au.dk/instruments/ttem. This is a non-invasive method. The tool records the subsurface response to a magnetic field.

The tool is towed behind a quad, which has some advantages such as being able to cover large areas quickly without compacting or damaging the soil.
