Marsh reclamation in the oil sands of Alberta: providing benchmarks and models of vegetation development
DownloadFall 2014
A key objective of the Alberta oil sands industry is to reclaim the post-mined landscape to “equivalent land capability” (Harris 2007). Vitt and Bhatti (2012) proposed a restoration framework for boreal disturbances. They suggested that to increase chances of achieving ecosystem equivalency and...

Methane Production and Emission Mitigation in Oil Sands Tailings Concurrent with Hydrocarbon Degradation under Nitrogen Limited Conditions
DownloadFall 2020
Alberta’s oil sands generate large volumes of tailings from bitumen ore processing. These tailings ponds produce biogenic methane, which can be measured across 60-80% of the tailings surface. Based on current surface area data and emissions studies, tailings ponds could account for 8% of Canada’s...

Collins, Catherine Elizabeth Victoria
Surface mining for bitumen extraction results in production of tailings that are deposited into large ponds. Tailings in the ponds support diverse microbial communities capable of metabolizing organic compounds and producing biogenic gases (methane, CH4 and carbon dioxide, CO2). Because of low...

The current hot water extraction method to recover bitumen from excavated oil sands ores after surface mining generates large volumes of fluid fine tailings that are temporarily deposited in oil sands tailings ponds. Promising techniques for tailings ponds reclamation such as end-pit lakes are...

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...

In the Prairie Pothole Region (PPR) of Canada wetlands once utilized for agricultural purposes are being restored to their pre-existing hydrological state. The overall objective of this research was to assess differences in microbial community structure and soil organic matter between native...

Microbial communities in organic substrates used for oil sands reclamation and their link to boreal seedling growth
DownloadFall 2012
Soil reconstruction in the Athabasca oil sands region utilises forest floor and peat materials as surface organic amendments to help reclaim decommissioned mine sites to upland boreal forests. The objective of this study was to characterize the microbial community in these two organic materials,...

Fall 2015
Assessment of microbial community development is required to determine the success of reclamation process on disturbed land after mining. Peat (PMM) or LFH mineral soil mix (LFH) is used as capping material in reclamation. Application of coarse woody debris (CWD) also facilitates reclamation by...
