The FORCIS database: A global census of planktonic Foraminifera from ocean waters

The FORCIS (Foraminifera Response to Climatic Stress) database is a synthesis grouping datasets on living planktonic foraminifera. We assembled foraminiferal diversity and distribution data in the global oceans from 1910 until 2018, curating published and unpublished datasets. This database includes data collected using plankton tows, continuous plankton recorder, sediment traps and plankton pump from the global ocean. The FORCIS database version 01 is composed of 5 files (“.csv” format). All data coming from different sampling devices were put into separate “.csv” files. Only the data of the CPR from the Southern Hemisphere have been separated from the Northern Hemisphere CPR data as the data structure is not the same (species counts resolved vs. binned total counts, respectively). Apart from the file of CPR data from the Northern Hemisphere that contains only metadata and binned total counts, all the remaining four files contain 4 blocks: Block 1: metadata (from column 1 to 71) Block 2: original counts (from column 72 to 274) Block 3: generated counts based on the validated taxonomy (from column 275 to 331). We added “_VT” to each species name to distinguish it from other taxonomy levels. E.g. “g_bulloides” became “g_bulloides_VT”. The number of species counted per subsample is also reported in the column “number_of_species_counted_VT” Block 4: generated counts based on the lumped taxonomy (from column 332 to 379). In this case, we added “_LT” to each species name. E.g. “n_dutertrei” became “n_dutertrei_VT”. We also calculated the number of species counted per subsample and reported it in the column “number_of_species_counted_LT” Foraminifera abundance data counts are reported in different categories in the blocks 1,2 and 3 and described in the table below: count_type unit Absolute ind/m3 Relative % Raw number of individuals Fluxes ind/m2/day Bin_Absolute ind/m3 Bin_Relative % Bin_Raw number of individuals Bin_Fluxes ind/m2/day For more details about the FORCIS database column description, please check the data descriptor paper Chaabane et al. (2023) (https://doi.org/10.1038/s41597-023-02264-2). The database is kept open for any new entries and the updated version will be released in csv format. The labels of updated versions of the released “.csv” files will contain the date of their publication and versioning number.FORCIS（有孔虫对气候压力的响应，Foraminifera Response to Climatic Stress）数据库是一套整合现生浮游有孔虫（planktonic foraminifera）相关数据集的综合资源。本库汇编了1910年至2018年间全球海洋范围内的有孔虫多样性与分布数据，对已发表与未发表的数据集进行了整理甄选，涵盖通过浮游生物拖网、连续浮游生物记录仪（continuous plankton recorder, CPR）、沉积物捕集器及浮游生物泵采集的各类数据。 FORCIS数据库01版包含5个后缀为".csv"的文件，所有来自不同采样设备的数据均存储于独立的".csv"文件中。仅南半球与北半球的CPR数据因数据结构差异（分别为物种计数解析模式与分箱总计数模式）而被分开存储。 除仅包含元数据与分箱总计数的北半球CPR数据文件外，其余4个文件均包含4个数据区块： 1. 区块1：元数据（第1至71列） 2. 区块2：原始计数数据（第72至274列） 3. 区块3：基于经过验证的分类体系生成的计数数据（第275至331列）。我们为每个物种名称添加"_VT"后缀以区分其他分类层级，例如"g_bulloides"将变为"g_bulloides_VT"。每个子样本的计数物种数亦在"number_of_species_counted_VT"列中予以记录。 4. 区块4：基于归并分类体系生成的计数数据（第332至379列）。此类数据中，我们为每个物种名称添加"_LT"后缀，例如"n_dutertrei"将变为"n_dutertrei_VT"。我们同时计算了每个子样本的计数物种数，并在"number_of_species_counted_LT"列中进行记录。 区块1、2、3中的有孔虫丰度计数数据分为不同类别，具体如下表所示： | 计数类型（count_type） | 单位（unit） | | ---- | ---- | | Absolute | ind/m3（个/立方米） | | Relative | %（百分比） | | Raw | 个体数 | | Fluxes | ind/m2/day（个/平方米·天） | | Bin_Absolute | ind/m3（个/立方米） | | Bin_Relative | %（百分比） | | Bin_Raw | 个体数 | | Bin_Fluxes | ind/m2/day（个/平方米·天） | 如需了解FORCIS数据库的列名详细说明，请查阅数据描述论文Chaabane等人（2023）（https://doi.org/10.1038/s41597-023-02264-2）。 本数据库对外开放新数据提交，更新版本将以.csv格式发布。已发布的".csv"文件的更新版本文件名将包含发布日期与版本编号。
