Seismic profiles P203 (top) and 301 (bottom): Stratigraphic unit boundaries are marked by colored lines. Different seismic stratigraphic units are labelled by circled numbers: I Molasse bedrock; II Glacial deposits; III Glaciolacustrine deposits; IV Lacustrine deposits. Multiple reflections are indicated with dashed yellow or green lines. The location of the core (HIBO19) is indicated by a black solid line in P203, whereas the projected location in P301 is marked by a grey one. The vertical scale is in two-way travel time [s], the horizontal axis is in common midpoints (CMP) with a 3-m spacing. Intersection of the two seismic lines indicated by vertical black line. See Fig. 1 for profile location
