  • We describe the diversity of marine copepods of Terra Nova Bay (TNB) sampled by 25 μm filters installed in the desalination unit (DU) of the Italian research station "Mario Zucchelli". The opening of the intake pipe of the DU is positioned at a depth of 4 meters and allowed a total of 2,116 specimens to be sampled and recognized. In addition, new occurrence records of copepod genera and species are reported in the same zone. We provide an overview of the marine copepods diversity reported for TNB. The total 2,116 individuals correspond to 14 genera and 15 species and are represented by 167 occurrence records in this dataset. Around 52% of the total number of species are new records for the TNB area are reported in this dataset.

  • 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.

  • This new dataset presents occurrence data for Porifera collected in the Ross Sea, mainly in the Terra Nova Bay area, and curated at the Italian National Antarctic Museum (MNA, section of Genoa). Specimens were collected in 331 different sampling stations at depths ranging from 17 to 1100 meters in the framework of 17 different Italian Antarctic expeditions funded by the Italian National Antarctic Research Program (PNRA). This dataset focuses on all classes (Calcarea, Demospongiae, Hexactinellida and Homoscleromorpha) of the Phylum Porifera (Kingdom Animalia), and includes a total of 807 specimens belonging to 144 morphospecies (with 95 taxa classified at species level and 49 at genus level), are included in the dataset and representing 12 orders and 30 families.

  • 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.

  • This dataset illustrates the distributional data of bryozoan species, belonging to the Classes of Stenolaemata and Gymnolaemata, collected in the Ross Sea and the Magellan Strait. The collection is curated at the Italian National Antarctic Museum (MNA, section of Genoa) and it includes a total of 311 specimens corresponding to 282 MNA vouchers and belonging to 127 morphospecies. Out of these, 100 were classified to species level and 27 to genus level, representing 3 orders and 34 families. The distributional data of Bryozoa came from different research expeditions, conducted between 1988 and 2014, and include 75 sampling stations, located between 18 and 711 metres of depth.

  • During the XXXVIII Italian Antarctic expedition (2022/23), 126 rocks have been sampled within the aim of “MAGIC” project in northern Victoria Land. They include the following lithologies: porphyry dike, pumice, pyroclastic rock, scoria, trachyte, tuff, volcanic rock dike, ash, basalt, breccia, dolerite, lamprophyre, lapillituff, lapillistone and lava. The investigated regions are Terra Nova Bay, Southern Cross Mountains, Random Hills, Evans Névé and Hallett Peninsula. Project: Magma-Ice interaction: late Miocene ice thickness and eruption tempo in northern Victoria Land

  • The Italian Collection of Antarctic Bacteria (CIBAN) was established in 1989 at the Department of Chemical, Biological, Pharmaceutical and Environmental Sciences of the University of Messina. CIBAN is one of the few collections in the world dedicated to Antarctic bacteria and, since its inception, it has grown to include 515 cold-adapted strains belonging to 69 Genera. Bacteria were extracted from seawater, sediment, and benthic organisms, mainly from the Terra Nova Bay marine area in East Antarctica. CIBAN also hosts bacterial isolates from the continent. Quality control: Strains are routinely streaked on agar plates every six months to control purity and viability. Method steps: All cultures are maintained in duplicate on agar slants at 4 °C. Antarctic strains are also preserved by freezing cell suspensions at – 80 °C in liquid broth to which 20% glycerol is added.

  • 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.
