(2020). Front. Earth Sci. 8:343. doi: 10.3389/feart.2020.00343 In the original article, the presented δ 18 O ara values were accidentally not corrected for the oxygen introduced during hydrolysis. The necessary correction results in slightly more positive δ 18 O ara values. The authors apologize for this mistake, and state that this does not change the scientific conclusions of the article in any way, particularly the fact that the calculated apparent fractionation (Ɛ 18O ara/p ) is constant along the Mongolian transect. However, as the apparent fractionation is 44 ± 2‰ (not 41 ± 2‰) and this would affect future data compilations and comparisons, we have corrected all δ 18 O ara and Ɛ 18O ara/p values in the text, the figures, and the supplementary material. We delete our hypothesis stated in the Supplementary Material that a decreasing partial CO 2 pressure might cause enhanced 18 O ara enrichment, because the correlation between Ɛ 18O ara/p and altitude is not significant anymore (R 2  0.09, p  0.14). All changes are highlighted in bold. A correction has been made to the Abstract. The corrected version is as follows: “The apparent fractionation Ɛ app , i.e., the isotopic difference between precipitation and the investigated compounds, shows no strong correlation with climate along the transect (Ɛ 2H n-C29/p −129 ± 14‰, Ɛ 2H n-C31/p −146 ± 14‰, and Ɛ 18O ara/p  +44 ± 2‰). Our results suggest that δ 2 H n-alkane and δ 18 O ara in topsoils from Mongolia reflect the isotopic composition of precipitation and are not strongly modulated by climate. Correlation with the isotopic composition of precipitation has root-mean-square errors of 13.4‰ for δ 2 H n-C29 , 12.6 for δ 2 H n-C31 , and 2.2‰ for δ 18 O ara , so our findings corroborate the great potential of compound-specific δ 2 H n-alkane and δ 18 O ara analyzes for paleohydrological research in Mongolia”.
