Kristen Coleman, a PhD candidate in Professor Jennifer Korosi’s lab and a Weston Family Northern Scientist, studies impacts to lake water quality as a result of permafrost thaw near the southern extent of permafrost in the Northwest Territories (NT), Canada. Here permafrost is sporadic, occurring beneath 10-50% of the landscape. She focuses on the impacts

The mud at the bottom of a lake isn’t just mud, it contains within it clues that, once decoded, tell us how the environment has changed over time. Clues can be anything that sinks to the bottom of the lake and is deposited into the mud. Often, this includes things that were living (and died)

The Canadian landscape has an abundance of lakes under pressure from multiple stressors. Lakes are sentinels of environmental change, as they archive changes occurring both within the lake, and in the surrounding terrestrial ecosystems within its watershed. Paleolimnology, that is, the study of lake sediment cores to reconstruct past climatic and environmental changes, helps us

Principal Investigator: Jennifer Korosi. Funding: NSERC. Term: 2017-2022. The research investigates how lakes are changing in response to thawing permafrost in the Taiga Plains and Mackenzie Delta Uplands regions (Northwest Territories) using lake sediment cores as natural archives of long-term environmental change.
