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.

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.
