Macroscopic charcoal record from Lake Satagay, Yakutia, Russia

These datasets of sediment core EN18224-4 from Lake Satagay (63°04'40.8N 117°59'52.8E), Central Yakutia, Russia, comprise the following data: (I) Radiocarbon age dating results by AWI MICADAS; (II) continuous macroscopic charcoal counts (> 150 µm), including the sum of particles per sample, their respective distributions in size classes (>150 µm, 300-500 µm, > 500 µm) and morphotype groups, as well as a low-resolution record of microscopic charcoal concentration from pollen slides (III) pollen and non-pollen palynomorph counts. The datasets have been described in more detail in the accompanying research paper. Metabarcoding results of sedimentary ancient DNA of terrestrial plants, also featured in the research paper, will be uploaded to the Dryad database (datadryad.org).

采自俄罗斯雅库特中部萨塔盖湖（Lake Satagay，地理坐标63°04'40.8"N，117°59'52.8"E）的EN18224-4号沉积物岩芯数据集包含以下数据：（I）由AWI MICADAS完成的放射性碳定年结果；（II）连续宏观炭屑计数（粒径>150μm）数据，涵盖每一样品的颗粒总数量、各粒径级别（>150μm、300~500μm、>500μm）的颗粒分布特征与形态类型组，以及源自花粉玻片的低分辨率显微炭屑浓度记录；（III）孢粉与非花粉孢粉型（non-pollen palynomorph）计数数据。本数据集的详细信息已在随附的研究论文中进行了完整阐述。研究论文中收录的陆生植物沉积古DNA元条形码（metabarcoding）测序结果，将上传至Dryad数据库（datadryad.org）。
