Glacier mass balance of the Melville South Ice Cap
Principal Investigator: Burgess, David O
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The objectives of this study are to: I) estimate the amount of water equivalent mass the Melville South Ice Cap loses (or gains) on an annual basis, and II) derive a long-term climate record from glacier measurements and weather station data in order to determine trends in climate change for this region of the Northwest Territories. Mass balance is measured at each of the 21 poles across the ic...


Community-based food systems research in Yellowknife, NT
Principal Investigator: Spring, Andrew
Licenced Year(s): 2017 2016
Summary: The objectives of this research is to support the implementation of the Yellowknife Food Charter and related local food activities in Yellowknife. This will be done through: 1) working with and supporting local groups (Ecology North and the Yellowknife Farmers Market) to identify community-based strategies to promote and implement local food production and develop a sustainable food system; 2) s...


Mapping, Language and Stories in Deline
Principal Investigator: Simmons, Deborah L
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010
Summary: As the community makes the transition to self-government, there has been an increased interest in language documentation through stories, song, and concepts of place in order to better understand what Dene government means. Governance thus forms one focal point of this research. The research team are particularly interested in the areas of variation, change and continuity in language, stories, son...


A Longitudinal Approach to Community Vulnerability and Adaptation to Climate Change
Principal Investigator: Pearce, Tristan D
Licenced Year(s): 2017 2016
Summary: The research aims to examine the processes and dynamism of climate change vulnerability in the Arctic through a longitudinal study in Ulukhaktok, NWT using fieldwork data from both 2005 and 2016. Specific objectives of this research are: 1) to document current exposure-sensitivities affecting Inuit subsistence hunting and adaptive strategies employed to manage them; 2) to compare current exposure-...


The effect of permafrost slumping on carbon delivery from land to water
Principal Investigator: Tank, Suzanne E
Licenced Year(s): 2017 2016 2015 2014
Summary: The objective of this study is to understand how permafrost slumping increases the mobilization of organic and inorganic carbon from land to water, and the effects of this movement on stream communities. To do this work, the research team will measure streamwater chemistry upstream and downstream of slump sites. The team will also examine the fate of this carbon by undertaking incubation experimen...


Quantifying permafrost thaw
Principal Investigator: Gruber, Stephan
Licenced Year(s): 2017 2016 2015
Summary: The Objectives of this research are to: 1) understand better how permafrost differs in temperature and chemical/physical characteristics from place to place; 2) understand how these different types of permafrost respond to change (climate/disturbance); and, 3) understand which future changes in permafrost are likely and which are less likely based on computer simulations. The researcher will t...


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
Licenced Year(s): 2017 2016 2015
Summary: Through this project the research team will address the following objectives: 1) determine the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system; 2) determine how these two types of feedback differ between the sporadic and discontinuous permafrost zones; 3) determine if s the reported decrease (increase) in net carbon dioxide (methane) exchange...


Geometries of an Arctic Highway: Transforming the Last Frontier into a Global Resource Frontier
Principal Investigator: Bennett, Mia
Licenced Year(s): 2017 2016
Summary: In light of rapid environmental alterations due to climate change and the Canadian North’s history of boom-and-bust cycles, this research has two objectives. The first is to understand the perspectives of residents in Inuvik and Tuktoyaktuk and government representatives in Yellowknife on the replacement of the seasonal ice road with a permanent all-weather road. The second is to discern who will ...


Examining the impacts of climate and environmental change on aquatic and terrestrial ecosystems of the Mackenzie region, NWT
Principal Investigator: Pisaric, Michael FJ
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: This research will continue the long term objective of documenting and understanding the impacts of recent climate change on northern terrestrial and aquatic ecosystems. The short term objectives of this research are: 1) to investigate the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems; 2) to examine the limnological implications of drained lakes on aquatic...


Using the past to inform the future: A paleoecological perspective of the impacts of drought and fire on lakes, permafrost and forests
Principal Investigator: Pisaric, Michael FJ
Licenced Year(s): 2017 2016
Summary: The objectives of this research are to examine the frequency and severity of past wildfire and drought (drought-like) conditions in the southern Northwest Territories. Specifically, the research team will examine the following questions: 1) how frequent and severe have fires been in the past; 2) are fires becoming more frequent/severe due to the impacts of climate change; 3) what impact does wildf...
