Moss and peat as monitors of contemporary and past rates of atmospheric dust deposition in the Athabasca Bituminous Sands Region
DownloadSpring 2017
Research Problem Since the introduction of open pit mining of the Athabasca Bituminous Sands (ABS) in 1967, this industry has generated considerable quantities of mineral dust that when released is injected into the atmosphere and settles in the surrounding environment. Despite this, a full...

Natural and anthropogenic inputs of arsenic and selenium to the environment in the Athabasca Bituminous Sands Region
DownloadSpring 2019
Industrial development of the Athabasca Bituminous Sands (ABS) in northern Alberta, Canada, has raised concerns that emissions of arsenic and selenium to the surrounding landscape and waterbodies have been increasing over time. To test this hypothesis, a comprehensive study of arsenic and...

Variations in Size and Optical Properties of Dissolved Organic Matter During Mixing at Large River Confluences: Implications for Source Discrimination in the Boreal Zone
DownloadSpring 2021
The functionality of dissolved organic matter (DOM) in natural waters depends on its size and composition. Identifying the sources and associated properties of DOM is vital to understand its effects on downstream ecosystems. River mixing has great potential to alter DOM quality, but its role in...
