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foraminiferal diversity and distribution data in the global oceans from 1910 until 2018, curating published and unpublished datasets.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（有孔虫对气候胁迫的响应，Foraminifera Response to Climatic Stress）数据库是一套整合现生浮游有孔虫（planktonic foraminifera）数据集的综合库。本库汇编了1910年至2018年全球海洋范围内的浮游有孔虫多样性与分布数据，对已发表及未发表的数据集进行了审核整理。该数据库涵盖了通过浮游拖网、连续浮游记录仪（Continuous Plankton Recorder, CPR）、沉积物捕集器（sediment traps）与浮游生物泵（plankton pump）采集的全球海洋观测数据。 FORCIS数据库v0.1版本包含5个".csv"格式文件，所有来自不同采样设备的数据均存储于独立的".csv"文件中。仅南半球连续浮游记录仪（CPR）数据与北半球CPR数据分开存储，原因在于二者数据结构存在差异：前者为解析至物种级的计数数据，后者为分级总计数数据。 除仅包含元数据（metadata）与分级总计数的北半球CPR数据文件外，其余4个文件均包含4个数据块： 1. 块1：元数据（第1至71列） 2. 块2：原始计数数据（第72至274列） 3. 块3：基于经验证分类学生成的计数数据（第275至331列）。我们为每个物种名称添加了"_VT"后缀，以区分于其他分类学层级。例如"g_bulloides"将变为"g_bulloides_VT"。每个亚样本的计数物种数量也会在"number_of_species_counted_VT"列中记录。 4. 块4：基于合并分类学生成的计数数据（第332至379列）。此类数据中，我们为每个物种名称添加了"_LT"后缀。例如"n_dutertrei"将变为"n_dutertrei_LT"（原文此处存在笔误，原写为"_VT"）。我们同样计算了每个亚样本的计数物种数量，并将其记录在"number_of_species_counted_LT"列中。 有孔虫丰度计数数据在块1、2、3中以不同类别呈现，具体分类如下表： | 计数类型（count_type） | 单位（unit） | | ---- | ---- | | Absolute（绝对计数） | ind/m³（个体/立方米） | | Relative（相对计数） | %（百分比） | | Raw（原始计数） | 个体数量 | | Fluxes（通量） | ind/m²/day（个体/平方米·日） | | Bin_Absolute（分级绝对计数） | ind/m³（个体/立方米） | | Bin_Relative（分级相对计数） | %（百分比） | | Bin_Raw（分级原始计数） | 个体数量 | | Bin_Fluxes（分级通量） | ind/m²/day（个体/平方米·日） | 如需了解FORCIS数据库列字段的更多详情，请查阅数据描述论文Chaabane等人（2023）（https://doi.org/10.1038/s41597-023-02264-2）。 该数据库对外开放新数据提交，后续更新版本将以".csv"格式发布。已发布的".csv"文件更新版本的文件名将包含发布日期与版本编号。
