Description
Isopoda Latreille, 1816 is an order that consists of a vast number of taxa, living and thriving in land, sea, fresh- and groundwater. Isopods in the Southern Ocean are highly speciose and well-represented from the shelf to deep-sea zones. Southern Ocean isopod marine species and their biogeography, yet studied since the firsts Antarctic expeditions, are however poorly known. Regarding Ross Sea, isopod communities and assemblages are still less studied than the Weddell Sea ones. New biogeographical data regarding Ross Sea isopods are presented here, examining the National Antarctic Museum (MNA) Genoa section samples belonging to 15 Antarctic Expeditions.
A total of 279 MNA samples were identified, resulting in 53 accepted species distributed in 24 families and 48 genera. From this identification, 15 species are considered new records for the Ross Sea area. GBIF and OBIS (Ocean Biodiversity Information System) (https://obis.org) databases, and bibliographic research were used as validation to the eventually new records for the Ross Sea area.

Couverture géographique
Geographic delimitation of this study is represented by the Southern Ocean. Ross Sea area is delimited by the Cape Adare -located in the northern Victoria Land- (West) to Cape Colbeck on Edward VII Peninsula (East); as northern delimitation an approximated point of the limit of the continental shelf is chosen, and southern limit of the marine shelf on the other side.

| Contrôle qualité | All records were validated. Coordinates were plotted on map to verify the actual geographical location. All scientific names were checked for typo and matched to the species information backbone of Worlds Register of Marine Species (http://marinespecies.org/) and LSID were assigned to each taxa as scientificNameID. Event dates are compliant to ISO 8601 standard. |
Description des étapes de la méthode:
- All the samples have been sorted and retrieved from the MNA collection.
- The samples have been recognized and classified to the lowest-possible taxonomic level using Leica MZ8 optical stereomicroscope.
- R statistical computing software has been used in order to perform comparative analysis and retrieve new records via rgbif package (rgbif package version 3.7.5) (Chamberlain et al.,2023).
- QGIS and Quantarctica (Matsuoka et al., 2021) has been used in order to produce maps and GIS-related biogeographical information.
