Abstract

The order Isopoda Latreille, 1816 consists of a large number of species occurring in terrestrial, marine, and freshwater environments. In the Southern Ocean (SO), this group is among the most speciose ones and occurs at all depths. Isopoda biogeography, despite being studied since the first Antarctic expeditions, is still poorly known from a geographical point of view, showing large occurrence gaps for some groups in specific sectors of the SO. In this paper, we update the isopod checklists of the Ross Sea and of some peri-Antarctic areas, such as the South Orkney Islands (SOI) and the South Sandwich Islands (SSI), based on the study of museum vouchers curated by the Italian National Antarctic Museum (MNA, Section of Genoa).
A total of 279 MNA samples from 15 different expeditions were studied. From this material, 41 accepted species distributed in 24 families, and 51 genera were recognized. Comparing this newly obtained information with the GBIF (Global Biodiversity Information Facility) and OBIS (Ocean Biodiversity Information System) portal, 15 species are here reported for the first time in the Ross Sea, with 5 new records in the Ross Sea Marine Protected Area. All records are new for the Terra Nova Bay area, for which a checklist of this group has never been produced before.

Spatial coverage

General spatial coverage: The geographical range of this study is the Southern Ocean.  In this study, we specifically focused on the Ross Sea (RS), the South Orkney Islands (SOI), and the South Sandwich Islands (SSI) areas. The Ross Sea area is delimited by Cape Adare, located in the northern Victoria Land (West), to Cape Colbeck on the Edward VII Peninsula (East); as northern and southern delimitation, CCAMLR 88.1 and part of 88.2 Statistical subareas are chosen. MNA samples retrieved in the SOI and the SSI areas are shown: CCAMLR 48.2 and 48.4 Statistical subareas are used in order to geographically determine the SOI and SSI areas. This dataset also comprehends 11 specimens belonging to the sub-antarctic Chilean area of Burdwood Bank.
Coordinates: 77°25'1.2''S and 54°57'59.76''S Latitude; 176°36'16.88''W and 176°15'28.19''E Longitude 

Temporal coverage: January 23, 1995 - December 5, 2018

Methods

Method step description: 
- . 	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.
Study extent description: This study focused on the voucher specimens of the Isopoda collection curated by the Italian National Antarctic Museum (MNA, Section of Genoa). MNA samples were collected in the framework of 15 different Antarctic research expeditions: PNRA Expedition X (1994/95), XI (1995/96), XIII (1997/98), XIV (1998/99), XVII (2001/02), XIX (2003/04), XXV (2009/10), XXVII (2011/12), XXVIII (2012/13), XXIX (2013/14), XXXII (2016/17), XXXIV (2018/19), and NSF (National Science Foundation) "Icefish04" and BAS (British Antarctic Survey) Expeditions JR15005 "SO-AntEco" and JR18003 "ICEBERGS2".
Sampling description: Sampling methods in this dataset vary from cruise to cruise: triangular dredge (IX, XVII PNRA exp.), large dredge (XXV, XXVII, XXVIII, XXIX PNRA exp.), Rauschert dredge (XIX PNRA exp., BAS JR15005 "SO-AntEco" 2016 exp.), Agassiz trawl (AGT) (XIII PNRA exp., XIX PNRA exp., BAS JR18003 "ICEBERGS2" 2018 exp.), Multiple Net Tucker Trawl (TT) (XXIX PNRA exp.), gill net (GN) (XXVII, XXVIII PNRA exp.), Small Hamburg Plankton Net (SHPN) (XXVIII PNRA exp.), trammel net (TN) (XXIX PNRA exp.), 65l Van Veen grab (IX, XI, XIV, XVII XIX PNRA exp.), box corer and multi corer (XXXII PNRA exp.), long line (LL) (XXVIII PNRA exp.) and manual collection through SCUBA diving (XVII, XXV, XXXIV PNRA exp.).
Quality control description: 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.
