This dataset contains transient data from a transient electromagnet field survey to the Aurus clay pan in the Sperrgebiet in the southern Namib Desert, Namibia. Using this data resistivity models of the subsurface can be calculated and the geometry and sedimentary thickness of the clay pan can be imaged. Measurements were carried out along two profiles using the TEM-FAST 48. The coincident loop setup was used with a loop size of (50 x 50) m^2. The transient data is provided in ASCII-format. All coordinates can be found in the kmz-file. Additionally, two figures are provided that show 1D inversion results of each profile.
