Active Layer Temperature Monitoring in Two Boreholes in Livingston Island, Maritime Antarctic: First Results for 2000–2006
This paper describes the active layer thermal regimes in two shallow boreholes, Sofía 275 m a.s.l. and Incinerador 35 m a.s.l., for which the ground temperature series has been recorded continuously from 2000 to 2006. The monitoring sites are located in Livingston Island, South Shetland Archipelago,...
