dmavraki@hcmr.gr https://imbbc.hcmr.gr/ 0000-0001-6775-530X CUSTODIAN_STEWARD 2024-10-30 ENGLISH The current historical paper dated back in 1892, is available online through the Biodiversity Heritage Library at https://www.biodiversitylibrary.org/page/10122164#page/379/mode/1up (pages 363-373). Its original title is "Campagne de la Melita, 1892. MOLLUSQUES RECUEILLIS SUR LES COTES DE LA TUNISIE ET DE L'ALGÉRIE, par Ph. DAUTZENBERG, ancient President de la Société". This dataset presents dredging sampling events carried out by researchers off the north coast of Tunisia and Algeria, at several depths. The digitization and standardization process are related to the list of stations sampled and the species - belonging to Phyllum: Mollusca (classes: Pelecypoda, Scaphopoda, Gastropoda,) and Brachiopoda - found. This historical paper is digitized through a Citizen Science Workshop organized by the Hellenic Centre in Marine Research in Lecce, on 15 November 2023, using the Zooniverse platform.

dmavraki@hcmr.gr https://imbbc.hcmr.gr/ 0000-0001-6775-530X The process started by volunteers using the Zooniverse platform, following a methodical workflow with simple tasks supported by tutorial, guidelines, and tips for transcribing the data and transforming it into the Darwin Core standards – a widely accepted, machine-readable format. This approach ensures that volunteers with various educational backgrounds can seamlessly participate in the transcription and FAIRification process of this historical marine biodiversity data. Volunteers managed to successfully complete all tasks of the CS project built in the Zooniverse platform, in a period of 76 days. Their responses were extracted in .csv format and with a specific-designed script (https://github.com/melinalou/Emodnet5/tree/main) and manual modification, the data were transformed into a human-readable .xlsx format. To ensure data quality, online tools such as the World Register of Marine Species (WoRMS) taxon match tool (https://www.marinespecies.org/tutorial_taxonmatch.php) were employed for cross-referencing taxonomic information, while Marine Regions (https://www.marineregions.org/) and Map Maker (https://maps.co/) were used to correct coordinate uncertainties Melita Campaign, 1892: Molluscs collected on the coasts of Tunisia and Algeria. The main equipment used, as described in the original paper, is the following: trawl, trawl and net and dredging. Taxonomy is mapped according to the WoRMS; while for localities we use the Marine Regions Gazetteer and the OBIS Map Tool. This is a historical paper and its digitisation took place in the framework of the EMODnet Biology phase 5. The digitisation process of the historical paper, which is available online in the Biodiversity Heritage Library, started during the Citizen Science Workshop organised on 15 November 2023 in Lecce and ended after data curation of the Hellenic Centre Marine Research Data Management Team. 2026-04-14T08:23:47Z Loulakaki M, Rallis I, Mavraki D (2024).
