During the XXXIV Italian Antarctic expedition (2018/19), 246 rocks have been sampled within the aim of the project "Early Paleozoic geodynamics of northern Victoria Land and implications for Gondwana reconstructions" in northern Victoria Land. They include intrusive, subvolcanic, volcanic, ultramafic and metamorphic rocks. The investigated regions are within Cape Hallett SS 58-60/2, Coulman Island SS 58-60/6, Freyberg Mountains SS 58-60/1, Mount Melbourne SS 58-60/9, Mount Murchison SS 58-60/5, Mount Soza SR 57-58/15, Ob' Bay SR 57-58/11 and Pomerantz Tableland SR 57-58/10 USGS sheets. Project: Early Paleozoic geodynamics of northern Victoria Land and implications for Gondwana reconstructions.

During the I Italian Antarctic expedition (1985/86), 73 rocks have been sampled within the aim of the project "Vulcanological survey of the Cenozoic volcanism, Victoria Land, Antarctica" in northern Victoria Land. They include different volcanic rocks. The investigated regions are within Mount Melbourne SS 58-60/9 and Mount Murchison SS 58-60/5 USGS sheets. Project: Vulcanological survey of the Cenozoic volcanism, Victoria Land, Antarctica.

During the XXXVII Italian Antarctic expedition (2021/22), 88 rocks have been sampled within the aim of “LARK” project in northern Victoria Land. They include intrusive, subvolcanic, volcanic, metamorphic and sedimentary rocks. The investigated regions are within Daniels Range SR 57-58/14, Freyberg Mountains SS 58-60/1, Mount Melbourne SS 58-60/9, Mount Murchison SS 58-60/5, Mount Soza SR 57-58/15, Sequence Hills SS 55-57/8 and Welcome Mountain SS 55-57/4 USGS sheets. Project: Linking the Aviator and Rennick Glacier Kinematics.

CRP-1 gravel-fraction core samples are clasts collected from the CRP-1 drill core (Cape Roberts) and are now preserved at the repository of the Museo Nazionale dell’Antartide. Clasts include intrusive, metamorphic, sedimentary and volcanic rocks.

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.

Culture Collection of Fungi From Extreme Environments (CCFEE) Tuscia Associated Section The Mycological Section of the MNA was founded in 2006 at the University of Tuscia, where the group of Systematic Botany and Mycology had established a collection of Antarctic microfungi. Since that time, the collection has been constantly implemented and today includes about 277 fungal strains belonging to 55 species. One of the main aim pursued by the CCFEE is the conservation of rock specimens, colonized by cryptoendolithic fungi and lichens, collected in the framework of PNRA expeditions. Part of the mission includes the study and valorisation of microfungi isolated from various types of Antarctic samples, including soil, mosses and, above all, rocks collected over about 30 years of Antarctic researches. Rocks are preserved at –20 °C and the cultures on slant agar, frozen form at – 80 °C; yeasts are freeze-dried. Samples curated at CCFEE are indicated by the code MNA-CCFEE-progressive in the database.

Antarctic and SubAntarctic Ophiuroidea - MNA (Section of Genoa)

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.

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.

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 volcanic, igneous and metamorphic rocks, and sediment. The investigated regions are within Cape Hallett SS58-60/2, Freyberg Mountains SS 58-60/1, Mount Murchison SS 58-60/5 and Mount Melbourne SS 58-60/9 USGS sheets.
