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.

In the Project PermVegNet (OSS-12) there are 14 sites between 73 and 78°S in which shallow boreholes of 1 m of depth are equipped with 4 thermistors (accuracy 0.2°C) placed at 2, 30,60, 100 or the maximum depth reachable close to 100 cm) to monitor the thermal regime of the active layer and to obtain one of the essential climatic variables (ECV) the active layer thickness that is the maximum depth of the annual 0°C isotherm. Here are added also other two deeper boreholes (Oasi A8 (31 m); Boulder Clay (3.6 m), where ALT is also determinable. In the same sites also a the air temperature, the soil moisture at 2 cm of depth in the ground and the PAR or PIR are measured to establish their relations to the ground thermal regime.
