A Mass-Energy Analysis of Permafrost and Vegetation Change Across a Mackenzie Mountain Treeline Ecotone: 1944 to 2017
Principal Investigator: Kershaw, Geoffrey GL
Licenced Year(s): 2017
Summary: The objectives of this project are to assess changes in ice rich permafrost landforms and plant community composition across a treeline ecotone and relate those larger shifts to specific physically based estimates of energy-mass budget for such features. The distribution of permafrost and vegetation both vary through time and space across the treeline, and while changes in one will affect the othe...


Slave Province Surficial Geology and Permafrost Study
Principal Investigator: Elliott, Barrett R
Licenced Year(s): 2017 2015
Summary: The objectives of the research are to generate new surficial geology maps and surficial geological studies covering approximately 5 50k National Topographic System (NTS) sheets, to install an new permafrost monitoring network at the treeline transition as well as to generate case studies of using small soil samples to detect a buried kimberlite and using passive geophysics equipment (measures eart...


Greenhouse Gas Exchange in the Outer Mackenzie Delta
Principal Investigator: Skeeter, Wesley R
Licenced Year(s): 2017
Summary: The objective of this campaign will be to measure the emission/uptake of methane and carbon dioxide at Fish Island in the outer Mackenzie Delta over a full growing season. This data will be used to determine the carbon balance of the island, and estimate the carbon balance of the land surfaces in the outer Mackenzie Delta. Additionally, the research team will investigate factors influencing the ex...


Sustainable Water Governance and Indigenous Law Project
Principal Investigator: Bakker, Karen
Licenced Year(s): 2017
Summary: The project goal is to enhance effective, equitable Indigenous co-governance of water resources through pursuing five objectives: 1) to critically conceptualize the potential for reciprocal coordination of, and complementarity between, evolving common ("Western") and Indigenous water law and governance frameworks; 2) to develop innovative methods for co-researching Indigenous Water Governance, b...


Erosion of old organic carbon in the Mackenzie River Basin
Principal Investigator: Hilton, Robert G
Licenced Year(s): 2017 2013 2011 2010 2009
Summary: The objective of this research is to better quantify the carbon source, age and fate in one of the largest rivers draining the high latitudes. The research team will sample river sediments and waters to establish temporal variability in OC source and age. The team will target high and falling flow (in June) when most sediment and water are exported. The research team will directly measure velo...


Radar Satellite Observations of Lake Ice Breakup and Freeze-up
Principal Investigator: van der Sanden, Joost J.
Licenced Year(s): 2017 2012 2010 2009
Summary: This project aims to evaluate and develop the utility of Canada’s future RADARSAT Constellation Mission (RCM) (launch 2018) for the monitoring of lake ice breakup and freeze-up. RCM-type radar images will be simulated using data from Canada’s current radar satellite – that is - RADARSAT-2. Validation data in the form of oblique aerial photographs are required to assess the accuracy of the image pr...


Geochemical and isotopic studies of Acasta Gneiss Complex, the oldest terrestrial rock on Earth
Principal Investigator: Lee, Seung-Gu
Licenced Year(s): 2017
Summary: The objective of this project is to collect rock samples from the Acasta Gneiss Complex, the oldest terrestrial rock on Earth, and to find a geochemical proxy which can shed light on the studies of early Earth rare earth element geochemistry and cosmochemistry. The field research will be carried mostly spot to spot based on the published geologic maps of previous researchers. The research team ...


The effects of wildfire on diverse aquatic ecosystems of the NWT
Principal Investigator: Tank, Suzanne E
Licenced Year(s): 2017 2016
Summary: The objective of this study is to determine the effect of fire on water quality within the southern NWT landscape. The research team will work across the Taiga Plains and Taiga Shield ecoregions. Differences in landscape between these regions will affect the catchment response to fire. The team will also target catchments with variable permafrost extent, and wetland/lake coverage. The research ...


A21 De-Fishing Program
Principal Investigator: Wells, David A
Licenced Year(s): 2017
Summary: The purpose of this project is to remove the majority of fish from within the A21 dike and transfer into Lac de Gras to allow for dewatering and construction to occur. The General Fish-out Protocol separates fishing effort into two phases. The Phase 1 fishing effort will begin with short duration gill nets and trap nets to target live release of fish into Lac de Gras. Fish captured will be tran...


Winter Flow Regime and Icing Dynamics of Tundra Streams near the Inuvik to Tuktoyaktuk Highway
Principal Investigator: Ensom, Timothy P
Licenced Year(s): 2017
Summary: The objectives of the project are to: 1) determine the spatial extent, distribution, and timing of winter icing events in streams along the Inuvik to Tuktoyaktuk Highway (ITH) through groundbased and aerial reconnaissance of stream crossings; 2) identify relations between physical watershed characteristics and icing dynamics through field observations and analyses of watercourse and catchment mo...
