Understanding of distribution and sources of polybrominated diphenyl ethers in the north and east of Great Slave Lake and coastal regions
Principal Investigator: Chen, Bing
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No. 5820. The proposed project will evaluate the temporal and spatial distribution of Polybrominated Diphenyl Ethers (PBDE) in the water and sediment of Great Slave Lake and surrounding communities, landfills, drinking water, and industries to identify the source of PBDEs. The concentration and distribution of PBDEs will b...


Sources and fate of microplastics in Great Slave Lake
Principal Investigator: Bourdages, Madelaine
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5004. The first objective of this project is to quantify microplastic concentration and composition in water, sediment, zooplankton, and air around Great Slave Lake. The second objective of this project is to examine if microplastic concentrations are greater near communities than the open water of Great Slave Lake. The thi...


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...


SAMMS: Sub-Arctic Metal Mobility Study
Principal Investigator: Wolfe, Brent BBW
Licensed Year(s): 2019 2018
Summary: The seven-year objective of Sub-Arctic Meteal Mobility Study (SAMMS) is to identify, quantify, and predict mobility of natural-source and legacy mine-source metals in soil, wetlands, and lake sediments that extend from former, present, and planned mine sites currently and as climate change alters the quantity and quality of dissolved organic matter produced and exported in subarctic NWT watersheds...


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
Licensed Year(s): 2019 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...


Long term and current variability in sources and sinks of carbon and nitrogen in terrestrial and aquatic ecosystems underlain by discontinuous and continuous permafrost
Principal Investigator: English, Michael C
Licensed Year(s): 2014
Summary: The objectives of this research project are: 1. to extract sediment cores from three different regions of the Northwest Territories namely: the low arctic tundra (continuous permafrost-Daring Lake), Taiga Shield northern boreal (widespread discontinuous permafrost-Wekweeti), and Taiga Shield boreal (sporadic discontinuous permafrost-Baker Creek Watershed) which provide the research team with a re...


Landscape scale flooding in the Great Slave Lake Plain
Principal Investigator: Armstrong, Terry
Licensed Year(s): 2014 2013 2012 2011 2010
Summary: The objectives of this project are to draw together multiple sources of information so that the research team may (1) examine change in lake area in this ecoregion, (2) assess amount of meadow habitat lost to rising water levels in core bison range, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and int...


Ecological Conditions in the Proposed Discharge Route of the Colomac Mine, NT
Principal Investigator: McGurk, Michael
Licensed Year(s): 2005 2004
Summary: The researchers will measure water quality, aquatic ecology and the status of fish populations in ponds and lakes along the proposed discharge route of mine water from the Colomac Mine (North Pond, L-Shaped Lake, Paddle Lake, Lake 315, and Lower Lake) and compare those data with data collected from reference lakes (Steeves Lake, Baton Lake, and Spanner Lake). Work will include taking three samples...


Taltson Hydro Project; Expansion Baseline Studies and Water Effects Monitoring Program
Principal Investigator: Uren, Shane
Licensed Year(s): 2004
Summary: The Expansion Project proposes to supply power to the Snap Lake, Gahcho Kue, Diavik and EKATI mine sites by expanding the existing infrastructure at the facilities on the Taltson River at Twin Gorges and at Nonacho Lake. Studies characterizing baseline e...


Massive Ice Study in Granular Deposits
Principal Investigator: Pollard, Wayne H
Licensed Year(s): 2006 2005 2004 2003
Summary: This study is an investigation of massive ice in granular deposits in the Mackenzie Delta area and northeastern North Slave region. In March, the team will travel by truck on existing winter roads or by helicopter from Inuvik to sites in the Mackenzie De...
