The ATEM method uses a transmitter loop, flown from either a helicopter or airplane, which transmits a waveform to excite the subsurface. ... To initiate the exploration of an ATEM inversion workflow ...

In this study we developed an electrical resistivity tomography (ERT) inversion algorithm that combines parametric and smooth inversion strategies. In regions where the subsurface is well constrained, ...

The transient electromagnetic (TEM) method is widely used in shallow surface engineering geological surveys due to its advantages such as light weight, high efficiency, and strong resolution. However, ...
