dmavraki@hcmr.gr https://imbbc.hcmr.gr/ 0000-0001-6775-530X CURATOR 2024-10-30 ENGLISH This historical dataset, available as "Pola" expedition: Mollusks - Biodiversity Heritage Library (biodiversitylibrary.org) pages 1-36, is related to the expeditions of the S. M. ship "Pola" in the eastern Mediterranean and the Adriatic. The great depths of the eastern Mediterranean and the Adriatic Sea are considered very poor, even poorer than those of the western basin. The whole report is separated into two parts. The first part deals with the threshing results in the eastern Mediterranean (Expeditions I-IV, 1890-1893), while the second those in the Adriatic (Expedition V, 1894). Each part is preceded by a list of the stations that have delivered molluscs, with a precise explanation of the geographical location, habitat, depth and date of the sampling event. This historical paper is digitised through a Citizen Science Workshop organised by the Hellenic Centre in Marine Research in Lecce, 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 The whole report is separated into two parts. The first part deals with the threshing results in the eastern Mediterranean (Expeditions I-IV, 1890-1893), while the second those in the Adriatic (Expedition V, 1894). The equipment used, as described in the original paper, is: small trawl, dredge samples, large hanging trawl, rake sampler and trawl. 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. 2026-04-14T08:23:00Z Dimitra Mavraki, Ioannis Rallis and Melina Loulakaki (2024).Digitization of "Pola" Expedition: Mollusks, in the Mediterranean and the Adriatic Sea, 1890-1894. https://doi.org/10.25607/mu0n0i accessed via GBIF.org on 2026-04-14.
