N-alkanoic acid hydrogen isotope composition and biomarker concentration of sediments from Lake Suigetsu, Japan (132,700 to 125,200 cal BP)
This dataset contains information about the compound-specific stable hydrogen isotope composition (δ2H) of n-alkanoic acids with 26, 28 and 30 carbon atoms. The samples originated from the Lake Suigetsu sediment cores. Data is provided at an approximately ~60 year resolution from 132.7 ka BP to 125.2 ka BP (n = 60). To accompany this data, the mass-normalised concentrations of key n-alkane and n-alkanoic acids are provided, alongside n-alkane index values. This data was collected to infer changes to the Lake Suigetsu catchment and the East Asian Summer Monsoon during Glacial Termination II.

Provenance & quality
Materials for this study were taken from the Lake Suigetsu sediment cores. Each set of samples underwent chemical preparation to isolate the components required following standard preparation methodologies. N-alkane and n-alkanoic acid concentrations were measured using a GC-FID and then corrected using an external standard calibration. Compound-specific n-alkanoic acid hydrogen isotopes were measured using a GC-IRMS connected via a furnace. This data was corrected (for the methylation of the n-alkanoic acids prior to measurement) using a mass balance approach.
