Biogeochemical impacts of glacial meltwaters across a High Arctic watershed (Lake Hazen, Nunavut, Canada)
DownloadFall 2018
Climate change across northern latitudes is fundamentally altering the hydrological cycle there, resulting in increased glacial melt, permafrost thaw and precipitation. Whereas enhanced glacial melt has potentially important implications for water quality and productivity in downstream freshwater...

Building Knowledge and Capacity to Support Healthy Eating and Active Living in the Canadian Arctic
DownloadSpring 2017
This qualitative single exploratory case study design, informed by Critical Social Theory (CST) (Habermas, 1982) and a participatory approach (Freire, 2000), explored how to build knowledge and capacity to support policy interventions that create conditions for healthy eating and active living in...

Spring 2014
ABSTRACT The germination of Clostridium estertheticum, the primary organism responsible for early blown pack spoilage, was investigated. Presence of C. estertheticum in blown packages was confirmed. The effect of pH, temperature and oxygen on germination of spores was established. Germination...

Development Of Shrub And Lichen-Dominated Biocrust Propagation And Establishment Techniques For Reclamation In Northern Environments
DownloadSpring 2022
Resource exploration and extraction in the arctic causes long lasting disturbances as natural recovery is a long and slow process in the north. With three Canadian diamond mines expected to close in the next fifteen years, many hectares of land will require revegetating. Research conducted in the...

Dissolved Organic Carbon Mobilization and Degradation Patterns in Retrogressive Thaw Slumps of the Peel Plateau, Northwest Territories, Canada
DownloadFall 2016
Anthropogenic climate change has affected the Canadian Arctic cryosphere, accelerating the development of retrogressive thaw slumps (RTS) across the Peel Plateau, NWT, Canada. RTS result from the thawing of ice-rich permafrost and develop due to ablation of ground ice exposed in the slump...

Peat mineral soil mix has been the predominant cover soil used in Athabasca oil sands reclamation. Use of LFH mineral soil mix (forest litter layers and underlying mineral soil) has recently been mandated by regulatory approvals. Effectiveness of these cover soil types to provide diverse, native...

Effects of retrogressive thaw slumping on particulate organic carbon dynamics in the Northwest Territories, Canada
DownloadSpring 2022
Climate change is increasing the frequency and intensity of thermokarst and accelerating the delivery of terrestrial organic material from previously sequestered sources to aquatic systems, where it is subject to further biochemical alteration. Rapid climate change in the glacially conditioned...

Automatic weather monitoring stations deployed in arctic regions are usually installed in hard to reach locations. Most of the time they run unsupervised and they face severe environmental conditions: very low temperatures, ice riming, etc. It is usual practice to use a local energy source to...
