Two boreholes were drilled near a Bulgarian Antarctic research base on Livingston Island to collect core samples for laboratory study of thermal properties. Thermal conductivity and diffusivity measurements were made on cores from the two boreholes, located 187 meters apart, to understand heat transfer in local soils and permafrost. Preliminary results found the highest thermal conductivity in cores from the PAPAGAL borehole and the highest thermal diffusivity in cores from the CALM borehole. Further tests will measure properties under saturated conditions to model the Antarctic climate. The study aims to interpret thermal flux in the region's soils and rocks.
