Spring 2014
The GeoStudio 2007 convection module a finite element program was used to examine convection in porous embankments and waste rock piles and compared to literature numerical and experimental examples by Goering and Kumar (1996) and Goering (2000) and field data from Diavik waste rock test piles. ...

Records of atmospheric mercury deposition and post-depositional mobility in peat permafrost archives from central and northern Yukon, Canada
DownloadFall 2017
Environmental archives provide a feasible means for studying the biogeochemical cycling of heavy metals including mercury (Hg). Although many temperate peat bogs have been successfully used to reconstruct natural and anthropogenic atmospheric Hg deposition fluxes, northern circumpolar permafrost...

Optimization of a Cover Design for Acid Rock Drainage Prevention in a Permafrost Environment
DownloadFall 2021
The extraction of sulfide-bearing waste rock can contribute to the generation of acid rock drainage (ARD). ARD is the effluent generated due to the oxidation of sulfide minerals which can be toxic to the receiving environment. Waste rock material which contains potentially acid-generating (PAG)...

Microbial community dynamics from permafrost across the Pleistocene-Holocene boundary and response to abrupt climate change
DownloadFall 2015
Permafrost houses active microbial communities adapted to constant sub-zero temperatures and anaerobic conditions. These extreme conditions make permafrost an excellent archive for long-term DNA preservation. Recent studies in the laboratory have shown a shift in permafrost bacterial communities...

Methylmercury production and export across the terrestrial-aquatic continuum in permafrost peatland catchments
DownloadFall 2023
Ongoing permafrost thaw in northern peatland catchments may increase the production and downstream delivery of neurotoxic methylmercury (MeHg) across the terrestrial-aquatic continuum. Peatlands in boreal-Arctic regions have large stocks of mercury (Hg) in frozen soils, accumulated through...

Long Term Effects of Wildfire on Permafrost Stability and Carbon Cycling in Northern Peatlands
DownloadFall 2017
Changing fire dynamics and increasing global temperatures are causing changes to the fire regime and permafrost stability in the Arctic. Models have separately predicted the widespread thawing of permafrost and increasing magnitude and intensity of wildfires over the next century. However, while...

Influence of wildfire and permafrost thaw on dissolved organic carbon (DOC) in northern peatlands; implications for lability and downstream transport
DownloadFall 2017
Peatlands in Canada’s western boreal forest are a major source of dissolved organic carbon (DOC) to downstream ecosystems, where DOC regulates carbon cycling, and can affect ecosystem productivity and habitat quality. Subarctic ecosystems are becoming increasingly vulnerable to the effects of...
