Permafrost at the ice base of recent pleistocene glaciations–inferences from borehole temperature profiles
Download2012
Paleo-temperature reconstruction from precise depth (>2.0 km) well temperature logs can offer information on whether the bed of an ice sheet was frozen. Inversion or upward extrapolation of the >2-km-deep geothermal profile is the only method by which temperature evolution at the base of...

Subsurface temperature signature of a large Pleistocene - Holocene surface warming in the North Alberta, Canada
Download2012
Majorowicz, J., Šafanda, J., Gosnold, W, Unsworth, M.
Recent results from a 2.3km deep temperature log in northern Alberta, Canada acquired as part of the University of Alberta Helmholtz-Alberta Initiative (HAI) geothermal energy project in 2010-2011shows that there is a significant increase in thermal gradient in the granites. Inversion of the...
