Age-depth model of HIBO19 composite section. The ages are given in ka BP and marked with squares. Uncertainties are indicated by x-axis error-bars: ¹⁴C (black, 2σ-range); OSL-IR50 (red, gaussian approach); Flimser Bergsturz correlating (blue, given uncertainty). Depth scale in meter composite depth, the marker-size exceeds the depth-interval of the samples. The probability histograms for the ¹⁴C-ages are given above the corresponding calibrated ages in black and for ¹⁴C-2 in semi-transparent green. The age-depth correlation below 8.83 mcd is indicated by a black dashed line, above, the model was just extrapolated with a straight line (yellow dashed line). The probability envelope is indicated in grey. The δ¹⁸0 data in [%] (National Centers for Environmental Information (NCEI), 2020) from 0 to 16 ka BP as a global temperature proxy with the geochronological ages are plotted below: Hol, Holocene; YD, Younger Dryas; BA, Bølling–Allerød; ELG, Early late Glacial. The boarders are extrapolated with vertical black dashed lines into the age-depth model. The combined composite photo, the stratigraphic units, and the lithotypes with the estimated grain size are given on the left side
