Extinction of austral diatoms in response to large-scale climate dynamics in Antarctica

This dataset is associated with the publication of Pinseel et al. "Extinction of austral diatoms in response to large-scale climate dynamics Antarctica". This dataset contains the following items arranged in different folders: 1. LM MICROGRAPHS & REFERENCES: this folder contains light microscopy micrographs of the lacustrine Miocene Continental Antarctic diatom flora described by Pinseel et al. For each taxon identified in the Miocene samples, at least one light microscopy micrograph is included. In addition, a reference list of literature used to identify the Miocene diatoms has also been included. 2. MIOCENE DIATOM DATABASE: this folder contains the original counts (relative abundances) of the lacustrine Miocene Continental Antarctic diatom flora, on both species and genus level. Two additional files in this folder give an overview of the full Miocene dataset, on both species and genus level, and including observations on taxa encountered outside the counts. 3. GLOBAL DIATOM GENUS DATABASE (GDGD): this folder contains the GDGD and associated files. 4. POLAR DIATOM SPECIES DATABASE (PDSD): this folder contains the PDSD and associated files. 5. R-CODE: this folder contains the original R-code used by Pinseel et al. to analyze the data and produce the figures. The R-code can be rerun using all csv-files that are included in this dataset in the folders on the GDGD, PDSD and the Miocene database.本数据集与Pinseel等人发表的论文《南极大型气候动力学驱动下的南方硅藻灭绝》("Extinction of austral diatoms in response to large-scale climate dynamics Antarctica") 相关。本数据集按不同文件夹整理了以下内容：1. 光学显微照片与参考文献（LM MICROGRAPHS & REFERENCES）：本文件夹收录了Pinseel等人所描述的南极大陆中新世湖相硅藻菌群的光学显微镜（light microscopy, LM）显微照片。针对中新世沉积物样品中鉴定出的每一个分类单元，均至少配有一张光学显微照片。此外，本文件夹还附带了用于鉴定该中新世硅藻的参考文献列表。2. 中新世硅藻数据库（MIOCENE DIATOM DATABASE）：本文件夹包含南极大陆中新世湖相硅藻菌群在物种和属级水平上的原始计数数据（相对丰度）。该文件夹另有两份文件，分别汇总了物种及属级水平的完整中新世数据集，并涵盖了计数过程中未纳入统计的分类单元的相关观测记录。3. 全球硅藻属数据库（GLOBAL DIATOM GENUS DATABASE, GDGD）：本文件夹收录了GDGD及其关联文件。4. 极地硅藻物种数据库（POLAR DIATOM SPECIES DATABASE, PDSD）：本文件夹收录了PDSD及其关联文件。5. R代码（R-CODE）：本文件夹包含Pinseel等人用于数据分析及图表生成的原始R代码。借助本数据集中GDGD、PDSD及中新世数据库文件夹内附带的所有CSV文件，可重新运行该R代码。
