Application of artificial substrate samplers to assess enrichment of metals of concern by river floodwaters to lakes across the Peace-Athabasca Delta
(University of Waterloo, 2021-05-19)Potential for downstream delivery of contaminants via Athabasca River floodwaters to lakes of the Peace-Athabasca Delta (PAD), northeastern Alberta (58.6°N, 111.8°W), has raised local to international concern. Prior ... -
Assessing hydrological processes controlling the water balance of lakes in the Peace-Athabasca Delta, Alberta, Canada using water isotope tracers
(University of Waterloo, 2007-05-22)One of the world’s largest freshwater deltas (~4000 km2), the Peace-Athabasca Delta (PAD), is located at the convergence of the Peace and Athabasca rivers and Lake Athabasca in northern Alberta, Canada. Since the early ... -
An Assessment of Hydro-ecological Changes at Two Closed-drainage Basins in the Peace-Athabasca Delta, Alberta, Canada
(University of Waterloo, 2006)Diatom analyses were carried out on sediment cores collected from two low-lying, closed-drainage basins (PAD 9 - 58º46. 46?N, 111º19. 48?W; PAD 12 - 58º57. 29?, 111º19. 74?) in the Peace sector of the Peace-Athabasca ... -
Development and application of paleolimnological analyses to disentangle the roles of natural processes and anthropogenic activities on contaminant deposition and hydrological conditions across a northern delta
(University of Waterloo, 2022-08-29)Freshwater ecosystems across northern Canada provide important habitat for wildlife and have long supported the traditional lifestyles of Indigenous communities. Multiple potential stressors threaten the security of water ... -
Evaluating the Influence of Flooding on Aquatic Food-webs in Basins of the Peace-Athabasca Delta Using Isotopic Tracers
(University of Waterloo, 2010-06-18)Periodic flooding has been widely believed to serve an important role in maintaining water levels and productivity of aquatic basins in floodplain landscapes. Here, I analyze four basins of contrasting flood frequencies ... -
Evaluating the role of local climate change on reduced freshwater availability at the Peace-Athabasca Delta using paleolimnology
(University of Waterloo, 2022-06-02)Abundant small, shallow lakes across northern freshwater landscapes are particularly sensitive to alteration of hydrological processes, which makes them vulnerable to multiple potential stressors. At the Peace-Athabasca ... -
Investigating the role of the Smoky River watershed on past ice-jam flood regimes at the Peace-Athabasca Delta via analysis of oxbow lake sediment cores
(University of Waterloo, 2022-06-06)The Peace-Athabasca Delta (PAD) in northern Alberta has been a focus of concern for decades due to decline in frequency and magnitude of ice-jam floods that sustain ecologically and culturally significant shallow perched ... -
Reconstruction of past variation in lake water balance at upstream Smoky and Wabasca watersheds to improve understanding of causes of lake drying in the Peace-Athabasca Delta
(University of Waterloo, 2023-01-23)Controversy persists regarding causes of recent lake-level drawdown within the internationally recognized Peace-Athabasca Delta (PAD), northern Alberta. Central to this debate are conflicting interpretations of causes of ... -
Use of water isotope tracers to elucidate hydrological conditions of lakes in the Peace-Athabasca Delta over space and time: A foundation for lake ecosystem monitoring
(University of Waterloo, 2022-01-17)Hydrological monitoring in complex, dynamic northern floodplain landscapes is challenging but increasingly important as these ecosystems come under threat from multiple stressors, including climate-driven decline in ...
