The objective of this dataset is to compile the historic records of marine and brackish diatom current species and genera reported for French coastal areas since the last quarter of the 19th century. The main focus is marine benthic diatoms, as occurrence datasets for phytoplankton (REPHY dataset) and for freshwater benthic diatoms (SEEE-Diatomées dataset) already exist for French coastal and inland waters, respectively. The dataset aims to fill this gap in knowledge by compiling reports that have been more difficult to reach (e.g., books, PhD theses and other grey literature), but also published papers on microphytobenthos research. The current version of the dataset has 11511 taxonomic entries found in 49 different references, dating from 1888 to 2019. A total of 2846 different taxa were compiled, 97% to species level or below, 3% to genus level. The dataset also offers information on geographic locations at 4 different levels, namely: site, county (i.e., département), region and seaboard. It also provides data on ecology (e.g., sampled substrate, habitat, growth forms) for most taxa. Moreover, a linkage to DiatomBase and WoRMS is given via AphiaID, their unique numerical database identifier. This linkage added relevant information for each species, such as higher taxonomic ranks or its accepted valid synonym.
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 11,511 records.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
The table below shows only published versions of the resource that are publicly accessible.

Diatoms (Bacillariophyceae) are listed to genus or species level. Nomenclature follows DiatomBase and higher classification is according to Cox (2015).

The personnel involved in the project:
Data inventory and compilation: Data sources were identified based on literature research and web-based search engines (e.g., Google or Web of Science). Both English and French languages were used when entering key terms during the search process, which included terms such as “diatoms” or “microphytobenthos” and was limited geographically to metropolitan France. The applicable data sources were digitally available in pdf format or in paper. Relevant information was manually transferred to a standard format in MS Excel.
|Study Extent||Compilation of the historic records of marine and brackish diatom current species and genera reported for French coastal areas since the last quarter of the 19th century.|
|Quality Control||Each taxonomic entry is unique, as it refers to a single taxonomic unit found in each one of the 49 references used in the dataset and reported for a specific location (at one to four geographical levels). A thorough cross-checking of species names and clean-up of duplicates was made. In order to standardize the taxonomic entries, the nomenclatural format of the taxa found in the original sources was adapted to the one used in DiatomBase and the World Register of Marine Species (WoRMS), thanks to the taxon match option available on the website of the latter (www.marinespecies.org). DiatomBase (Kociolek et al. 2022) is primarily a nomenclatural database that updated and extended the Catalogue of Diatom Names (Fourtanier and Kociolek 2011), but it is also an authoritative open-access reference system for diatom taxa, which is universally recognized, and it is edited by 23 taxonomic editors world-wide. It is managed by VLIZ and shares with WoRMS a unique identifier, known as the AphiaID, for every species name. This identifier enables to link the species name to an internationally accepted standardized name and associated taxonomic information, such as accepted names, synonyms and current classification. The linkage of the current dataset to DiatomBase/WoRMS was made through a “worms” R package (version 0.2.2, J. Holstein 2018) that allows to retrieve the taxonomic information available for each AphiaID. The dataset was adjusted to the Darwin Core specifications (Wieczorek et al. 2012) in order to be published in the GBIF network.|
