Summary

[This dataset is embargoed until February 1, 2025]. This dataset contains information about the stable oxygen isotope composition (δ18O) of bulk diatom silica, and the compound-specific stable hydrogen isotope composition (δ2H) of n-alkanoic acids with different chain lengths. Samples originated from the Lake Suigetsu sediment cores. Data is provided on an approximately centennial (100-year) resolution from 22,040 cal BP to 9,980 cal BP (n = 120). To accompany this data, the mass-normalised total lipid extract and n-alkanoic acid concentrations of key chain length n-alkanoic acids are provided. This data was collected to infer changes to the East Asian Winter Monsoon and East Asian Summer Monsoon during Glacial Termination I. This work was supported by the National Environmental Isotope Facility (grant number 2308.0920) and the NERC IAPETUS2 Doctoral Training Partnership.
