Shallow geothermal heat in Western Canada: climatic warming impact changes with time– depth
Gain of heat and temperature in the shallow subsurface over the last decades/century has been impacted by the industrial period climatic surface air temperature (SAT) increase. Detailed study of the available temperature-depth data based on 43 wells with single and repeated temperature logs done by the first author has been combined with data base information (Jessop et al 2005) to create temperature maps at depth. Based on these 43 logs it is shown that the heat flux increases with depth in most cases for the available depth data range from surface to some 200m. Model of heat flow versus depth based on the surface air temperature changes through the industrial epoque climatic warming explains the data. Spatial and depth distribution of available temperature and heat gain through the provinces of the Western Canadian Sedimentary Basin WCSB shows that drilling closer to surface is more economic than deeper to 50-100m
The last millennium climate change in Northern Poland derived from well temperature profiles, tree-rings and instrumental data
In order to reconstruct the air temperature variations in Northern Poland for the last millennium observational and proxy (tree-ring widths) data were used. For the first time the ground surface temperature (GST) for Northern Poland was reconstructed based on geothermal data (well temperature profiles). A general warming trend is observed for both the GSTH (GST Histories) derived from geothermal data and instrumental data, in particular, for the last 200 years

Report on the geothermal research in borehole GTPVLT-1 (Litoměřice)
The report provides information about geothermal research in borehole GTPVLT-1 in the Czech Republic, which included (i) repeated temperature logs during and after the borehole drilling, (ii) measurements of thermal conductivity and diffusivity of the encountered rock samples, (iii) measurements of radioactive isotopes content of uranium, thorium and potassium in the encountered rock samples and calculation of their radiogenic heat production, (iv) determination of the terrestrial heat flow in the borehole and (v) prognosis of temperature expected down to the depth of 5 km
