Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT
Principal Investigator: Smith, Sharon S
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Summary: This project continues the on-going monitoring program of permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT. The objectives are: 1) To provide baseline knowledge of permafrost and terrain conditions (specifically ground temperature and permafrost active layer thickness) and improve characterization of terrain sensitivity in the Macken...


Holocene Glacier Fluctuations in Nahanni National Park Reserve, Northwest Territories, Canada
Principal Investigator: Menounos, Brian p
Licenced Year(s): 2017 2016
Summary: The objective of the study is to date the formation of terminal moraines fronting Brintnell Glacier, and analyze the glacigenic signature within the sediments of Glacier Lake in order to develop a robust chronology of glacier change on the Brintnell-Bologna Icefield. This decade to century scale chronology will be compared to regional-to-hemispheric climate proxies to evaluate the climate sensitiv...


Influence of changing active-layer thickness on permafrost peatland trace gas exchanges and carbon balance
Principal Investigator: Sonnentag, Oliver
Licenced Year(s): 2017 2016 2015 2014 2013
Summary: The project of the present application is the continuation of year-round eddy covariance measurements of carbon, water and energy fluxes at Scotty Creek, established in 2013 as part of licence #15816. The key methodology is tower-mounted micrometeorological measurements around the eddy covariance technique using an open-path infra-red gas analyzer and a sonic anemometer. These measurements are ...


The Arctic Great Rivers Observatory III
Principal Investigator: Holmes, Robert Max
Licenced Year(s): 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 will take measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) and try ...


Drivers and consequences of shrub distribution on the tundra landscape
Principal Investigator: Baltzer, Jennifer L
Licenced Year(s): 2017 2016
Summary: The objective is to determine the growth and recruitment responses of trees and shrubs to changing climate conditions near tree line and improve the understanding of the drivers of shrub patch expansion on the tundra. Ten shrub patches were selected for measurement and paired permanent monitoring plots were established at each patch; one plot was centred on the patch of interest, the other on t...


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...
