N-alkanoic acid hydrogen isotope composition and biomarker concentration of sediments from Lake Suigetsu, Japan (132,700 to 125,200 cal BP)

[This dataset is embargoed until July 1, 2025]. 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. This work was supported by the Quaternary Research Association, the Scottish Alliance for Geoscience, Environment and Society, the School of Geographical and Earth Science (University of Glasgow) and the NERC IAPETUS2 Doctoral Training Partnership.

本数据集将于2025年7月1日解禁。该数据集收录了关于具有26、28和30个碳原子的n-烷酸特异稳定氢同位素组成（δ2H）的信息。样本源自西湖组沉积岩心。数据以约60年的分辨率提供，时间跨度为132.7千年前至125.2千年前（样本数量为60）。为配合此数据，还提供了关键n-烷和n-烷酸的质量归一化浓度，以及n-烷指数值。收集此数据旨在推断冰川期末期二阶段中西湖流域和东亚夏季季风的变化。本研究得到了第四纪研究协会、苏格兰地球科学、环境与社会联盟、格拉斯哥大学地理与地球科学学院以及NERC IAPETUS2博士培训合作伙伴的支持。关于此数据集的详细信息，请查阅https://doi.org/10.5285/e3ebeca1-ce57-40f9-8237-85d8aa543ff8。
