The Hydrogeophysics Group (HGG) at Aarhus University has worked with geophysical methods in the hydro-domain for more than 30 years. Since the beginning of the 2000s, the group has had a strong focus on TEM methods beginning with the airborne SkyTEM system and later with ground-based systems, both stationary and towed (tTEM).

In the last few years, a new generation of TEM instruments has been developed, allowing for monitoring applications. Previously, any geophysical monitoring would typically be carried out with ERT type instruments as they could deliver the long-term stability and robustness required. But with the newest TEM instruments, the group has a low-power, physically small, and non-drifting instrument that allows them to see relatively deep with a high and consistent accuracy. These TEM monitoring instruments have been installed across Denmark, South Africa, and Senegal. This presentation will discuss the main instrument design considerations as well as potential applications for these kinds of instruments. Besides showing some of the field cases, the presentation will also include discussions of instrument requirements and lessons learned in aiming to have continuous daily measurements with remotely installed instruments.
