Corrigendum to “Biomarker reconstructions of temperature and hydroclimate variability in Vietnam during Marine Isotope Stage 3” [Quat. Sci. Rev. 341 (2024) 108893] (Quaternary Science Reviews (2024) 341, (S0277379124003949), (10.1016/j.quascirev.2024.108893))

The authors regret a minor error identified in this article, which stemmed from an error in the isotope mass balance correction to account for the carbon added during the methylation reaction. Upon correcting this error, the δ¹³C_wax and the subsequently computed δD_precip data were slightly adjusted. However, these changes do not affect the interpretations in the manuscript. The Results section 4.1 should now read as follows, with updated δ¹³C_wax and δD_precip values highlighted in bold: “The average chain length (ACL) of the n-alkanoic acids (C₂₂-C₃₄) is 28.9 (see Supplementary). The mean of Carbon Preference Index (CPI) (ratio of the even-to-odd chain length abundance) is 3.5 (see Supplementary), with a minimum value of 2.4, suggesting a good preservation of organic compounds in the sediment. Overall, there is an increase of δ¹³C_wax from -24.5 to -18.5 ‰ (Fig. 5f). Although δ¹³C_wax records indicate a long-term gradual increase, the range of the isotopic variation is relatively small (∼6 ‰) when considering that the end-members of δ¹³C_wax values of C₃ and C₄ plants in tropical regions are −33.4 and −20.7 ‰ (Garcin et al., 2014). Indeed, the fraction ([Formula presented]) indicates that C₄ plants remained dominant throughout the record, accounting for 73 to 100% of vegetation in all samples (see Supplementary). A small contribution of C₃ plants, 5–25%, occurs between 53 and 48 cal ka BP. The δD_wax of the n-C₃₀ acids at KS16 range from −173 ‰ to −192 ‰ (Fig. 5h). Our data show a fluctuation of ∼19 ‰ between 54 and 49 cal ka BP, followed by more stable values centered around ∼ −176 ‰ until 39 cal ka BP. The final sample at ∼37 cal ka BP hints at an abrupt decrease to −190 ‰. The inferred δD_precip exhibits a ∼26 ‰ in amplitude ranging from -74 ‰ to -48 ‰ (Fig. 5h), implying a similar overall pattern to δD_wax. The offset (ε_water-wax) between δD_precip and δD_wax is relatively constant between 118 ‰ to 125 ‰, suggesting that the vegetation changes do not greatly impact δD_wax.” We have also updated Figure 5 and the Appendix table to reflect the corrected δ¹³C_wax and δD_precip values. All data associated with this study, including these updates, will be made publicly available in the NOAA NCEI Paleoclimatology database.
