Impacts of climate change on wildfire risk in boreal forests in the Northwest Territories
Principal Investigator: Asselin, Hugo
Licensed Year(s): 2019 2018
Summary: The three main objectives of this research are: 1) to reconstruct the multi-century history of wildfire and vegetation in the Northwest Territories by analyzing charcoal contained in lake sediments; 2) to establish the links between recent fire activity and climatic data by studying tree growth rings (annual resolution); and, 3) to combine this scientific knowledge to indigenous knowledge obtained...


Permafrost in the western Arctic
Principal Investigator: Kokelj, Steve V
Licensed Year(s): 2019 2018 2017 2016
Summary: The primary objectives of this research are: 1) to develop and test new methods of monitoring permafrost landscape change; 2) to investigate the impacts of natural and human disturbance on permafrost terrain and the ground temperature conditions in natural environments and in communities; and 3) assess the physical and chemical characteristics of permafrost. To achieve the objectives the resear...


North Slave Permafrost Study: Characterizing and Predicting Discontinuous Permafrost for Climate Change Adaptation
Principal Investigator: Wolfe, Stephen A
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010
Summary: This activity describes and predicts the occurrence of discontinuous permafrost in the northern Great Slave Lake region to assist in planning, development and maintenance of community and industry infrastructure. Changes in climate are affecting permafrost distribution, temperatures and geotechnical conditions. Different landscapes across the region are exhibiting varying responses to warming. Thi...


Vegetation Productivity on the Bathurst Caribou Range
Principal Investigator: Danby, Ryan K
Licensed Year(s): 2019 2018
Summary: The two main objectives are: to map changes in vegetation productivity on an annual basis across the Bathurst caribou herd’s range using satellite imagery obtained from NASA’s MODIS sensor (available since 2000) and analyze these data to identify where the most significant changes have occurred; and to collect and analyze data on the growth, establishment, and mortality of shrubs and trees over th...


Impact of climate change on catchment biogeochemistry in plains and shield regions
Principal Investigator: Olefeldt, David
Licensed Year(s): 2019 2018
Summary: The objective of this research is to identify impacts of climate change and permafrost thaw on pond methane emissions, and on water chemistry in streams that drain peatland-rich catchments. Impacts on methane emissions will be assessed. Specific objectives are : 1) to characterize the trends and variability in magnitude of methane emission from ponds along climate gradients within both the Tai...


BEARWATCH: Monitoring Impacts of Arctic Climate Change using Polar Bears, Genomics and Traditional Ecological Knowledge.
Principal Investigator: Lougheed, Stephen C.
Licensed Year(s): 2019 2018
Summary: This research will integrate and map polar bear knowledge systems and translate findings into a community-based monitoring protocol that will track polar bear population responses to environmental change. Research questions include: i1) Are polar bear science data, existing Traditional Ecological Knowledge (TEK), and historical records from the fur trade, explorer’s personal accounts and governmen...


How will fish communities in Gwich’in and Inuvialuit lakes respond to climate change?
Principal Investigator: Gray, Derek K
Licensed Year(s): 2019 2018 2017
Summary: The purpose of this project is to obtain baseline data for fish communities in Gwich’in Settlement Area (GSA) and Inuvialuit Settlement Region (ISR) lakes and use these data to predict future changes in fish communities caused by climate change. Specific objectives are: 1) to develop a baseline data set for fish populations, fish habitat, water quality, and water temperature for small and m...


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...


The Arctic Great Rivers Observatory III
Principal Investigator: Holmes, Robert Max
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The Arctic Great Rivers Observatory project studies the six largest rivers in the Arctic: the Mackenzie and Yukon Rivers in North America, and the Ob', Yenisey, Lena, and Kolyma Rivers in Russia. The research team are interested in how climate change is impacting Arctic rivers. The team make measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) and try to de...


The frontline of permafrost thaw: a transect of eddy covariance towers across the southern Taiga Plains to better understand changing regional carbon and water budgets
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2019 2018 2018 2017 2016 2015
Summary: Through this project the following objectives will be addressed: What is the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system? How do these two types of feedback differ between the sporadic and discontinuous permafrost zones? Is the reported decrease (increase) in net carbon dioxide (methane) exchange based on plot- (<1m2) and ecosystem-scale...
