Continuous seismic monitoring data from Mt. Melbourne volcano (Victoria Land) are recorded for volcanic risk mitigation. The dataset includes raw continuous waveforms and processed products like Root Mean Squared (RMS) amplitude time series and seismic event counts. Seismic signals cover volcanic seismic signals, ice-quakes, and microseism background signals. Processed data is available for direct download via the provided dashboard links, whereas raw continuous seismic data can be obtained upon request to the point of contact/PIs.

Multidisciplinary dataset acquired within the fumarolic ice caves of Mt. Melbourne (Aurora/MC1, MC3, and MC4). Includes continuous gas concentrations (CO2, H2O, CH4, etc.), soil CO2 fluxes, and high-resolution air/soil temperatures (depths of 20 cm and 60 cm). Data is used to track indicators of volcanic unrest in polar environments.

Antarctic ecosystems have a high number of species, that are closely linked to the presence of sea ice and seasonal cycles. This biodiversity is subject to anthropogenic and natural influences. Macrozoobenthic communities are the 'biological memory' of the ecosystem, structuring themselves as a function of environmental changes over the years. Macrozoobenthos samples were collected using suction dredging and scraping techniques, in soft and hard bottoms. Sampling occurred in 5 different sites.

Terra Nova Bay (Ross Sea, Antarctica), characterized by a moltitude of ice tongues flowing from land to sea, represents an ideal study site for understanding the complex interaction between relative sea level variations and ice sheet dynamics during the Holocene. The DISGELI project, thanks to the combination of innovative technology and traditional methods for geomorphologic and stratigraphic analysis, aims to: i) reconstruct the local variations of the East Antarctic Ice Sheet after the Last Glacial Maximum; ii) provide a time constrain for the deglaciation processes along the coast; iii) reconstruct, with unprecedent detail, the relative sea level variations during Holocene in the Drygalski basin. The morpho-bathymetric and topographic data obtained through this study will be integrated using digital terrain models based on the analyses of key areas onland, where palaeo-coastlines and sea-level markers have been identified.

The only borehole equipped the international standard and within the network managed by the PNRA OSS-12 is located very close to MZS named OASI. The site (-74.74167;164.1;52 m slm) is a flat granitic outcrop. The borehole was drilled with compressed and refrigerated air in the austral summer of 2007 and equipped in 2008. The borehole is 31 m deep and the ZAA is ca 26m and there are 20 thermistors at different depths. Here, only the temperature closest at ZAA depth has been reported.

We present the snow samples collected for the PASSPORT project during the 2025-2026 Antarctic Campaign. We report the number of snow samples collected, the depth of the samplings, their geographic information, the sampling and treatment date, the treated volume, snow density and temperature and weather conditions.
