Short summary

The manuscript re-analyses seismic data from the UPPLAND profile in the Fennoscandian Shield, focusing on P- and S-wave velocity models. Significant differences between prior and present models emerge in the lower crust and mantle and in the Moho depth. The new model suggests ca. 7.1 km s-1 in the lower crust and 8.05 km s-1 in the upper mantle, with Moho at 43–50 km. Two tectonic interpretations are proposed to explain these findings, emphasising the complexities of seismic data interpretation.
