Signature of the last ice age in the present subsurface temperatures in the Czech Republic and Slovenia

Predicting heat flow in the 2001 Bhuj earthquake (<i>M</i><sub>w</sub>=7.7) region of Kachchh (Western India), using an inverse recurrence method

“…This phenomena has also been seen in North American data (Gosnold et al, 2005). Similar inferences have been obtained in other studies too (Pandey, 1981;Safanda and Rajver, 2001;Kukonen and Joeleht, 2003;Majorowic et al, 2008). It would mean that the heat flow may have been underestimated for many areas.…”

Lithosphere thermal structure at the eastern margin of the Bohemian Massif: a case petrological and geophysical study of the Niedźwiedź amphibolite massif (SW Poland)

“…For the model of recent changes, the temperature before the onset of the five glacial cycles considered was assumed to be equal to the mean temperature of -4°C according to the findings from inversions of deep[2.4 km and as deep as 7 km wells in Poland and Czech Republic (Poland-Czech Republic; Majorowicz et al 2008;Mottaghy et al 2009;Szewczyk and Gientka 2009;Š afanda et al 2004;Š afanda and Rajver 2001). Based on the above published evidence, the cycles are assumed to have an amplitude 14°C (-7°C, ?7°C, respectively).…”

“…This model simplifies likely more complicated changes in surface temperature in the past; however, these are not known with high precision (Jessop 1990;Demezhko et al 2006). Our model of surface forcing history is based on the approximation of such history giving the best fit to the measured temperature-depth variations in this part of Europe (Poland-Czech Republic; Majorowicz et al 2008;Mottaghy et al 2009;Szewczyk and Gientka 2009;Š afanda et al 2004;Š afanda and Rajver 2001) and depicts the most important features of the high amplitude surface temperature changes. The most recent high amplitude change from recent Pleistocene glacial period to Holocene is the largest influence upon observed variations of heat flow with depth due to diffusive nature of the process.…”

Deep 3D thermal modelling for the city of Berlin (Germany)

“…Calculating bulk thermal conductivities inversely from local heat flow density and log-derived interval temperature gradients (Blackwell and Steele 1989;Fuchs and Förster 2010) Another potential explanation would be an inherited paleoclimatic effect, induced by lower surface temperatures during the Pleistocene ice ages and responsible for reduced thermal gradients in the shallow subsurface at present-day (e.g. Clauser et al 1997;Norden et al 2008;Šafanda and Rajver 2001;Šafanda et al 2004). A related non-equilibrium of the measured temperature logs, i.e.…”
