Abstract
To obtain the shear wave velocity profiles, we make use of a global inversion approach based on the neighborhood algorithm to invert the interpreted branches of the dispersion curves. Within the uncertainty given by the apparent spread of forward models we find that besides a well defined sediment velocity range also a reasonable minimum estimate of bedrock depth and bedrock velocity can be achieved. The Vs estimate for the best model in Horstwalde ranges from ~Â 190Â m/s at the surface up to ~Â 390Â m/s in the bottom of the soft sediment column. The bedrock starts earliest around 200Â m depth and bedrock velocities are higher than 1000Â m/s. In Löbnitz, we observe slightly lower velocities for the sediments (~Â 165-375Â m/s for the best model) and a minimum thickness of 75Â m.
