A changing North: The implications of high-volume groundwater extraction and reduced water availability on sub-arctic peatland hydrology, connectivity, and geochemistry
(University of Waterloo, 2022-07-05)Patterned bog and fen peatlands of the Hudson Bay Lowlands (HBL) currently make up 90% of land cover in this region and form one of the largest continuous peatland complexes in the world. A globally significant storage of ... -
Characterizing the transport of hydrocarbon contaminants in peat soils and peatlands
(University of Waterloo, 2018-09-04)Widespread transportation corridors crossing Canadian peatlands make these landscapes vulnerable to hydrocarbon spills. After a spill happens, free hydrocarbon spreads in the peat layer forming a free-phase plume. Water ... -
Chemical characterization of construction materials and solute transport in peat from the Nikanotee Fen watershed at the Athabasca oil sands region, Alberta, Canada
(University of Waterloo, 2017-02-22)Overburden and tailings materials from oil sands production were used as construction materials as part of a novel attempt to create a self-sustaining, peat accumulating fen-upland ecosystem. To evaluate the potential for ... -
The CO2 dynamics and hydrology of an experimental Sphagnum farming site
(University of Waterloo, 2017-01-23)Sphagnum farming (or cultivation) is a recent land management strategy in reclaimed peatlands. The goal of Sphagnum farming is to cultivate Sphagnum fibers on a cyclic basis. Sphagnum moss is non-vascular and requires high ... -
Dissolved organic carbon production and transport in a constructed watershed in the Athabasca Oil Sands Region, Alberta
(University of Waterloo, 2018-01-23)Within the Western Boreal Plains, a significant amount of surface cover has been removed through open-pit oil sands mining activities, which includes fen peatlands. Fen construction has been performed on the post-oil sands ... -
Evaluating parameter fitting and model design for unsaturated processes in peatlands
(University of Waterloo, 2019-04-08)Growing Sphagnum moss for peatland restoration and fibre farming requires the proper moisture regime be maintained; thus, there is a desire to optimize growth by creating ideal hydrological conditions. Sphagnum mosses have ... -
The feasibility of field based mechanical compression to reduce the capillary barrier effect and increase CO2 sequestration in a restored cutover peatland
(University of Waterloo, 2019-01-28)Ten years after restoration was implemented at the Bois-des-Bel peatland (BdB) in Quebec, there was limited hydrological connectivity between the regenerated Sphagnum moss and the remnant cutover peat due to the formation ... -
The Hydrochemical Fate and Transport of Treated Domestic Wastewater Contaminants During a Wastewater Polishing Experiment in a Sub-Arctic Ladder Fen Peatland
(University of Waterloo, 2016-09-27)Protecting northern aquatic ecosystems is critical to ensuring the sustained use of these environments; however, with increasing industrial and residential development pressures in this region the safe and effective treatment ... -
The Hydrogeochemistry of a Constructed Fen Peatland in the Post-Mined Landscape in the Athabasca Oil Sands Region, Alberta, Canada
(University of Waterloo, 2016-09-28)Large areas of land within the Athabasca Oil Sands Region (AOSR) have been subjected to open pit mining to recover bitumenous oil sands. Following extraction, oil sands require the addition of solvents to optimize the ... -
Hydrological and Geochemical Implications of Aquifer Depressurization on Expansive Peatland Systems in the Hudson/James Bay Lowlands
(University of Waterloo, 2016-04-08)The ecological integrity of the peatlands of the Hudson/James Bay Lowlands (HJBL) is vulnerable to hydrological changes associated with climate change and resource development. Dewatering of an open-pit mine (the DeBeers ... -
Hydrology of a Constructed Fen Watershed in a Post-mined Landscape in the Athabasca Oil Sands Region, Alberta, Canada
(University of Waterloo, 2016-01-20)Peatlands (i.e., wetlands with organic soil) cover approximately 12% of Canada’s total land area, 18% of Alberta’s land base and nearly half of the landscape in Canada’s Western Boreal Plain. Some of these peatlands overlay ... -
Hydrology of a Moderate–Rich Fen Watershed Prior to, and Following Wildfire in the Western Boreal Plain, Northern Alberta, Canada,
(University of Waterloo, 2018-09-05)Peatlands are a dominant land feature in the Athabasca Oil Sands Region (AOSR) of the Western Boreal Plain (WBP), northern Alberta, Canada, comprising >50% of the total land area, many of which are moderate–rich fens. The ... -
Projecting the Hydrological and Geochemical Evolution of a Constructed Fen Watershed in the Athabasca Oil Sands Region, Alberta, Canada
(University of Waterloo, 2021-05-11)Ongoing commercial bitumen surface mining operations have fundamentally altered large areas of forested uplands and fen peatlands in the Athabasca Oil Sands Region (AOSR), Alberta, Canada. Returning fen peatland functions ... -
Response of Peatland Microbial Community Function to Contamination by Naphthenic Acids and Sodium in the Athabasca Oil Sands Region, Alberta, Canada
(University of Waterloo, 2016-10-20)Reclamation of closed oil sands mining operations in former pristine boreal ecosystems of the Athabasca Oil Sands Region of Alberta, Canada (AOSR) requires construction of new fen land uses such as peatlands in order to ... -
Salinity Effects on Dissolved Organic Carbon Concentration and Quality in a Constructed Fen Peatland, Fort McMurray, AB
(University of Waterloo, 2020-08-05)In northern Alberta, oil sands mining disturbs the landscape; reclamation to an “equivalent land capability” is required, and industry is testing peatland construction as part of landscape reclamation. To determine if these ... -
Saturated and vadose zone fate and transport of a continuously released tracer in a sub-arctic bog peatland
(University of Waterloo, 2017-02-22)In Ontario’s James Bay Lowland, sub-arctic bog and fen peatlands make up 90% of the landscape. Increasing resource extraction operations in this area pose a risk of contaminant release into these systems, both intentional ... -
Sulfur biogeochemistry in a constructed fen peatland in the Athabasca Oil Sands Region, Alberta, Canada
(University of Waterloo, 2018-05-14)In peatlands, increased sulfate (SO42-) availability can stimulate dissimilatory SO42- reduction (DSR), allowing it to become a prominent anaerobic carbon (C) mineralization process. In turn, methane emissions may be ... -
