Abstract:
This dataset contains a vegetation-corrected reconstruction of the hydrogen isotope composition of precipitation (δ2Hprc) from sediment core ROT21, collected from Rotsee in central Switzerland in October 2021. The record covers 0.0567–12.8696 ka BP and comprises 63 observations reported with sediment depth and calibrated age. Reconstructed δ2Hprc values were calculated from measured n-C29 alkane δ2H values. Changes in the relative contributions of grasses and woody plants were accounted for using the relative abundances of long-chain n-alkanes and vegetation-specific apparent hydrogen isotope fractionation factors derived from a compilation of modern European plant-wax measurements. Uncertainty was propagated using 10,000 Monte Carlo simulations per sample; the dataset reports the central reconstructed values and the lower and upper limits of the 68% confidence interval in per mil relative to Vienna Standard Mean Ocean Water (VSMOW). The reconstruction was produced to separate variation in precipitation isotope composition from changes in sedimentary plant-wax δ2H caused by shifts in vegetation. The vegetation correction and uncertainty propagation were implemented using the R scripts by Santos (2026) archived at Zenodo (https://doi.org/10.5281/zenodo.18694984); the development repository is available at https://github.com/RicardoANSantos/Rotsee_d2Hprc. The underlying measured plant-wax data are archived in PANGAEA under doi:10.1594/PANGAEA.987812, and the complete methodology is described by Santos et al. (2026).
