Lakes as sentinels of environmental change in discontinuous permafrost peatlands
Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No.5468. The goal of this project is to understand and predict how lakes in discontinuous permafrost peatlands are changing in response to climate warming and loss of permafrost. The field activities for 2023 will focus on three regions/objectives: Inferring long-term environmental change in the Five Fish Lakes (Lue Túé ...

Trajectories of landscape change due to thawing permafrost
Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4727. The research team will use lake sediment cores to track the history of shoreline permafrost thaw slump activity over the last several thousand years, and associated lake ecological responses to thaw slumping, in order to provide a long-term context for present-day observations. The team will select three pairs of ...

Climate change impacts on lake ecosystems of the western Canadian Arctic
Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2019
Summary: The objectives of this research is to: 1) determine if thaw slumping results in the loss of a large-bodied zooplankton species (Daphnia) from lakes; and 2) measure polychlorinated biphenyl concentrations in lake sediments near the Distant Early Warning Line site in Tuktoyaktuk, to assess whether legacy contamination is still evident. The research team will be collecting sediment cores from ...

Long-term aquatic ecosystem change at the southern limit of permafrost
Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2019 2018
Summary: The goal is to reconstruct long-term environmental change (hundreds to thousands of years) by examining chemical and biological fossil remains preserved in lake sediment cores, in order to better understand how thawing permafrost impacts lake ecosystems. 1) Water chemistry and plankton survey The research team will collect lake water samples from the study lakes to analyze for water chemistry...

Long-term perspectives on aquatic ecosystem change with thawing permafrost
Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2017
Summary: The research team will re-survey 70 lakes originally sampled in 2005/06, to assess how conditions have changed in the intervening decade as thaw slumping has intensified and the Inuvik-Tuktoyaktuk Highway (ITH) was constructed. The team will assess how lake ecosystems responded to past climatic shifts throughout the post-glacial history of these lakes (10,000 years), and use these records to provi...
