Subglacial recharge into the Western Canada Sedimentary Basin—Impact of Pleistocene glaciation on basin hydrodynamics
Brine springs discharging from Devonian carbonates of the Western Canada Sedimentary Basin have distinct water chemistry from brines in laterally equivalent units deeper in the basin. Stable isotopeExpand
Relation between climate variability and groundwater levels in the upper carbonate aquifer, southern Manitoba, Canada
Modeled trends of key climate variables in the Winnipeg area show that the annual mean temperature has increased by about 1 °C over the past 105 years. Potential impacts of climate change onExpand
Humboldt’s spa: microbial diversity is controlled by temperature in geothermal environments
It is demonstrated that temperature exerts a strong control on microbial diversity when considered over most of the temperature range within which life is possible. Expand
Origin and geochemistry of saline spring waters in the Athabasca oil sands region, Alberta, Canada
Abstract The geochemistry of saline spring waters in the Athabasca oil sands region (AOSR) in Alberta (Canada) discharging from Devonian carbonate rocks into the Athabasca and Clearwater rivers wasExpand
Predicting average annual groundwater levels from climatic variables: an empirical model
On the basis of one-dimensional theoretical water flow model, we demonstrate that the groundwater level variation follows a pattern similar to recharge fluctuation, with a time delay that depends onExpand
Catastrophic dispersion of coal fly ash into oceans during the latest Permian extinction
The eruption of the Siberian Trap flood basalts resulted in the heating and combustion of coals and organic-rich sediments at the time of the Permian mass extinction. The presence of char in distantExpand
Distribution and diversity of Verrucomicrobia methanotrophs in geothermal and acidic environments.
There appears to be a thermophilicgroup and a mesophilic group of methanotrophic Verrucomicrobia, however, both were detected only in acidic geothermal environments. Expand
Supraglacial sulfur springs and associated biological activity in the Canadian high arctic-signs of life beneath the ice.
Cell counts and DNA analyses confirm bacteria are present in the spring system, and a limited number of sequenced isolates suggests that complex communities of bacteria live within the glacial system. Expand
