Here we present the surface snow samples collected along the international EAIIST project traverse, which took place in 2019-2020 Antarctic Campaign. We report the number of surface samples (upper 10 cm and integrated 1m samples) collected and their geographic information.

Here we present the snow pits collected along the international EAIIST project traverse, which took place in 2019-2020 Antarctic Campaign. We report the number of snow pits collected, the depth of the samplings and their geographic information.

This dataset reports the height observations of the Italian stake farm at the Concordia Station, Antarctica. The stake farm consists of 13 stakes, separated from each other by 10 m, arranged in a cross shape structure, located approximately 800m southwest of the Station and sampled on monthly basis or so.

We will collect stool samples from the volunteers at the Mario Zucchelli Station at different time points. The samples will be analysed by shotgun metagenomic sequencing, considering only the microbial component.

We will collect oral samples from the volunteers at the Mario Zucchelli Station at different time points, using safe and not harmfull kits. Samples will be analysed by shotgun metagenomic sequencing, considering only the microbial component.

We will collect skin samples from the volunteers at the Mario Zucchelli Station at different time points, using safe and not harmfull kits. Samples will be analysed by shotgun metagenomic sequencing, considering only the microbial component.

This dataset reports the snow density observations at the Concordia Station, Antarctica. A snow trench is dig once per month (or every three months during winter) in the clean area near the Station (< 1 km). Four measurements are taken inserting a core barrel (with a diameter of 4.5 cm and a length of 25 cm) horizontally into the snow at 10 cm depth, and four more measurements are taken inserting another core barrel (with a diameter of 3.7 cm and a length of 9.2 cm) vertically, from the surface to 10 cm depth. The snow density is calculated from the weight.

This dataset contains a selection of bias-corrected data from the preoperational MiKlip system for decadal climate predictions (Mueller et al., 2018) used within the project PNRA18_00199-IPSODES. The adopted method for bias correction is described in the file bias_correction.pdf attached to the dataset. Also data from the assimilation run are provided. Nomenclature of variables follows that of the original MiKlip output. Mueller, W., et al. A Higher‐resolution Version of the Max Planck Institute Earth System Model (MPI‐ESM1.2‐HR). J. Adv. Model.

This dataset reports the snow density, temperature and hardness observations from the surface to 1 m depth at the Concordia Station, Antarctica. A snow trench is dig once per month (or every three months during winter) in the clean area near the Station (< 1 km). The snow density measurements are taken inserting a core barrel (with a diameter of 4.5 cm and a length of 25 cm) horizontally into the snow every 10 cm from 0 to 1 m depth. The snow density is calculated from the weight. For each layer the temperature and the hardness (ranging from 1 to 6) are also recorded.

Here we present the firn cores collected along the international EAIIST project traverse, which took place in 2019-2020 Antarctic Campaign. We report the number of firn cores collected, the depth of the samplings and their geographic information.
