This time we will investigate three sites in Namibia: Tsondab Vley, Aurus Clay Pan and Roter Kamm crater. The seismic survey, for which we are requesting the instruments, will consist of a couple of crossing 2D high-resolution seismic lines per site. The accelerated weight-drop will be used as a seismic source and the resulting seismic data will be analyzed in terms of reflections and refractions to provide a good basis for the envisaged drilling
