  • Amphibolites were taken during the Italian Antarctic Expeditions since 1985 and now are preserved at the repository of the Museo Nazionale dell’Antartide. They come from different regions of Antarctica where the geological evolution took place at different times and during different orogenic events. Many of them have been classified at the Museo Nazionale dell’Antartide and have been the object of petrological, geochemical, geochronological and geomagnetic researches.

  • Distribution records of sea cucumbers (Echinodermata, Holothuroidea) based on the collection stored at the Italian National Antarctic Museum (MNA, section of Genoa) is an occurrence type dataset published by Italian National Antarctic Museum (MNA). The dataset comprises a total of 328 distributional records, each one corresponding to a voucher specimen stored at the Italian National Antarctic Museum (MNA) – Genoa section. These records originate from the sampling activities performed in the context of eleven different research projects that took place during 11 scientific polar expeditions conducted in the Ross Sea and the Antarctic Peninsula. In total, 89 different sampling events were conducted using a variety of sampling instruments and methodologies.

  • Alkali feldspar trachytes are rare rocks sampled during the Italian Antarctic Expeditions since 1993 and are now preserved at the repository of the Museo Nazionale dell’Antartide. They come from Victoria Land and formed during the Cenozoic events. They have been classified at the Museo Nazionale dell’Antartide and studied by researchers for petrological, geochemical, geochronological and tectonic aims.

  • Alkali feldspar syenites are rare rocks sampled during the Italian Antarctic Expeditions since 1988 and are now preserved at the repository of the Museo Nazionale dell’Antartide. They come from Victoria Land and formed during two different magmatic events. They have been classified at the Museo Nazionale dell’Antartide and studied by researchers for petrological, geochemical, geochronological and tectonic aims.

  • We present a data set on Antarctic biodiversity for the phylum Rotifera, providing taxonomic information, geographic distribution, location, and habitat. The data set gathers all the published literature about rotifers found and identified across the Continental, Maritime, and Subantarctic biogeographic regions of Antarctica. A total of 1422 records of rotifers in Antarctica found from 1907 to 2018 is reported, with information on taxonomic hierarchies, updated nomenclature, geographic information, geographic coordinates, and type of habitat. All taxa belonging to Rotifera were considered. In particular, we gathered data from records at the species, genus, family, class (Bdelloidea, Monogononta, Seisonacea), and phylum (Rotifera) level (Fontaneto & De Smet 2015)

  • 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. 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. This dataset describes the abundance and distribution of Isopoda of the 15 antarctic campaigns: PNRA Expedition Xth (1994/95), XIth (1995/96), XIIIth (1997/98), XIVth (1998/99), XVIIth (2001/02), XIXth (2003/04), XXVth (2009/10), XXVIIth (2011/12), XXVIIIth (2012/13), XXIXth (2013/14), XXXIIth (2016/17), XXXIVth (2018/19), and NSF (National Science Foundation) "Icefish04", and BAS (British Antarctic Survey) Expedition JR15005 "SO-AntEco" and JR18003 "ICEBERGS2". at Southern Ocean between 23 January 1995 and 05 December 2018.

  • Andesites are rocks sampled during the Italian Antarctic Expeditions since 1986 and are now preserved at the repository of the Museo Nazionale dell’Antartide. They come from Victoria Land and formed at different times under different igneous events. They have been classified at the Museo Nazionale dell’Antartide and studied by researchers for petrological, geochemical and geochronological aims.

  • Basalts are rocks sampled during the Italian Antarctic Expeditions since 1985 and are now preserved at the repository of the Museo Nazionale dell’Antartide. They come from different regions and formed at different times under different igneous events. They have been classified at the Museo Nazionale dell’Antartide and studied by researchers for petrological, geochemical and geochronological aims.

  • Aplites are rocks sampled during the Italian Antarctic Expeditions since 1985 and are now preserved at the repository of the Museo Nazionale dell’Antartide. They come from different regions and formed at different times under different igneous events. They have been classified at the Museo Nazionale dell’Antartide and studied by researchers for petrological, geochemical and geochronological aims.

  • Arkoses are rare rocks sampled during the Italian Antarctic Expeditions since 1989 and are now preserved at the repository of the Museo Nazionale dell’Antartide. They come from Victoria Land and testify the existence of the supercontinent Gondwana. They have been classified at the Museo Nazionale dell’Antartide and studied by researchers for their petrography, provenance and fossiliferous content.
