Journal Articles & Research Abstracts (Helmholtz-Alberta Initiative)
These are peer-reviewed articles and abstracts that can be openly shared according to publisher policies. The research was funded in part by the Helmholtz-Alberta Initiative, which is an independent international research partnership that effectively amalgamates the scientific and technical expertise of the Helmholtz Association of German Research Centres and the University of Alberta to jointly develop solutions to key challenges in fields such as energy, ecosystem and resource informatics, and health.

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...

Leskiw, L. A., Chanasyk, D. S., Nemirsky, C. L., Naeth, M. A., Brierley, J. A., Bock, M. D., Archibald, H. A., VandenBygaart, A. J.
With increasing anthropogenic activity, the areal extent of disturbed soils is becoming larger and disturbances more intense. Regulatory frameworks must incorporate reclamation criteria for these disturbed soils, requiring consistent descriptions and interpretations. Many human altered soils...

Scale-dependent covariance of soil physical properties above and below a soil horizon interface: Pedogenic versus anthropogenic influences on total porosity
Download2011
Dyck, M. F., Kachanoski, R. G.
The basic unit of soil – the pedon – is described as the minimum, three-dimensional unit of soil representative of the variability of soil horizon dimensions and morphology. Pedogenic processes responsible for soil horizon and soil profile formation are primarily hydrologic in nature. The...
