De Beers - Gahcho Kué Environmental Monitoring Program
Principal Investigator: Kramers, Patrick
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010
Summary: The objective of the proposed studies is to obtain information on the environment once Project activities commence to determine potential project effects. The proposed studies will include the collection of air quality, geochemistry, hydrology, water and sediment quality, and fish and aquatic resources, dustfall, vegetation and soil information. The studies (further defined below) are designed...


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): 2018 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...


Impacts of forest fire on discontinuous permafrost in the south-western Northwest Territories
Principal Investigator: Lewkowicz, Antoni G
Licenced Year(s): 2018 2017 2016
Summary: The research goal is to look at how permafrost is changing following forest fire over a range of environmental conditions, with the purpose of improving how change is modelled in the future. The fires of 2014 in the southwestern NWT provide an opportunity to examine how discontinuous permafrost responds to disturbances. This work is being carried out in collaboration with an inter-university team ...


Geo-mapping for Energy and Minerals Program: Western Arctic Project - Smoking Hills
Principal Investigator: Smith, Rod
Licenced Year(s): 2018
Summary: This research will provide the geological information needed to correlate Cretaceous (<140 Ma) and younger geology of the Smoking Hills with that on Banks Island and elsewhere in the Canadian High Arctic and Mackenzie-Beaufort region. This will provide a greater understanding of the age and evolution of the offshore Canada Basin (Arctic Ocean). Studies of kimberlite indicator minerals will provide...


Planning and Collection of Data on Boreal Wildfire Effects: Studies of broad-scale 2014 Wildfires in NWT, Canada
Principal Investigator: Bourgeau-Chavez, Laura L
Licenced Year(s): 2018 2017 2016 2015
Summary: The goal of this project is to identify and collect remote sensing and field data to support the science necessary to investigate the impacts and consequences of the 2014-15 wildfires in Northwest Territories, Canada and to better understand the vulnerability of the Carbon-rich boreal peatlands to burning. Field crews will navigate to pre-selected sample locations and collect at each location: ...


The Arctic Great Rivers Observatory III
Principal Investigator: Holmes, Robert Max
Licenced Year(s): 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. We are interested in how climate change is impacting Arctic rivers. The research team will take measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) and try to det...


Inuvik SuperDARN Radar Facility
Principal Investigator: McWilliams, Kathryn
Licenced Year(s): 2018 2017
Summary: Just as high and low pressure systems drive normal weather, high and low voltages drive space weather. The radar network is designed to measure these voltage patterns several hundred kilometers above the ground, and these patterns project out into space along the Earth's magnetic field lines. The radar installation is rather simple, requiring transmitting and receiving electronics in a small bu...


Toward Predicting Future Tundra Carbon Balance
Principal Investigator: Lafleur, Peter M
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2007 2005 2004
Summary: The broad goal of this research is to increase our understanding of tundra carbon balance of terrestrial and aquatic ecosystems and predict into the future the impacts of climate warming on these systems. Since we are interested in all aspects of the tundra carbon balance a variety of methods are employed. These can be broken down into 4 basic categories: 1. Tundra-atmosphere fluxes - the ex...


EarthScope Transportable Array
Principal Investigator: Busby, Robert W
Licenced Year(s): 2018 2017 2016 2015 2014 2013
Summary: This project consists of a large deployment of ground motion sensors (~270 total) throughout Alaska and western Canada; 28 located in Yukon Territory and 5 in the Northwest Territory. Each station senses the ground movement from distant earthquakes and sends data via satellite or radio modem to a central receiving point in San Diego. The purpose of collecting these data is to study deep geologic s...


Mackenzie Mountains Aeromagnetic Survey
Principal Investigator: Kiss, Frank
Licenced Year(s): 2018
Summary: The objective of this airborne survey is to acquire high-resolution aeromagnetic data. This survey will be flown to improve the knowledge of the area. It will support potential future ground-based geological mapping and to provide basic information to support mineral exploration. The survey will consist of approximately 53,000 line km of surveying flown at a line spacing of 800 m (or 2625 feet)...
