Biogeochemical impacts of glacial meltwaters across a High Arctic watershed (Lake Hazen, Nunavut, Canada)
DownloadFall 2018
Climate change across northern latitudes is fundamentally altering the hydrological cycle there, resulting in increased glacial melt, permafrost thaw and precipitation. Whereas enhanced glacial melt has potentially important implications for water quality and productivity in downstream freshwater...

Evaluating the Biogeochemical and Geotechnical Behavior of Oil Sands Tailings in Pit Lakes and Mitigating Pit Lake Turbidity with Biofilms
DownloadFall 2023
Permanent storage and reclamation of oil sands mine waste (fluid fine tailings, FFT) in pit lakes has been proposed by industry. Pit lakes are considered best practice in terms of geotechnical stability, however, there are numerous challenges and knowledge gaps surrounding this proposed oil sands...

Fluvial inorganic carbon cycling across divergently evolving permafrost landscapes (Yukon and Northwest Territories, Canada)
DownloadFall 2019
Across the circumpolar north, rapid warming and intensifying hydrologic cycles are accelerating permafrost thaw and strengthening land-freshwater linkages. Among the most significant implications of this change is the mobilization of large amounts of previously sequestered organic and inorganic...

Fall 2018
Ice masses in the Antarctic, Greenland, and Canadian Arctic cover approximately 10% of the Earth’s surface, contain approximately 70% of the Earth’s freshwater, and are the top contributors to eustatic sea level rise. In recent years, these polar glacier systems have experienced significant...

Stream Carbon Flux in the Northern Pacific Coastal Temperate Rainforest: Seasonal DOC Transport and CO₂ and CH₄ Emissions
DownloadSpring 2020
Streams in British Columbia's humid, organic-rich Pacific Coastal Temperate Rainforest (PCTR) deliver globally significant yields of soil-derived dissolved organic carbon (DOC) to the ocean, which can affect ocean acidification, provide energy to coastal food webs, and off-gas to the atmosphere...

Unseen and Unknown: Microbial Community Diversity in a Rapidly Changing High Arctic Watershed on Northern Ellesmere Island, Canada
DownloadFall 2018
Arctic watersheds are currently undergoing great alterations due to human induced climate change. Current models predict increases in High Arctic temperatures and precipitation of up to 8.3°C and 40%, respectively, by 2100, which will have profound impacts on the arctic hydrological cycle,...

Fall 2024
Forests generally provide the highest-quality water among all land cover types, but they are highly susceptible to disturbances like wildfire. Climate change is driving a trend toward hotter, drier conditions that have been intensifying fire regimes worldwide. The Pacific Coastal Temperate...
