Pine Point Project
Principal Investigator: Drolet, Andree
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4582. These studies are to support upcoming regulatory applications for the Pine Point Project being developed by Pine Point Mining Limited (PPML). The additional baseline studies include but are not limited to surface water quality and quantity, groundwater water quality, aquatic environment monitoring, fish and fish ha...


Taltson Twin Gorges Hydro Generating Facility Aquatic Effects Monitoring Program (AEMP) 2019
Principal Investigator: Miller, Matthew
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4565. The objective of this project is to conduct Aquatic Effects Monitoring. This will include three parts: 1) Riparian Habitat and Fish Usage Assessment. This is a study to monitor the trends and fluctuations of the aquatic environment along the riparian zones within the Taltson River from Nonacho Lake to Twin Gorges ...


Con Mine 2019 Supplemental Benthic Invertebrate Sampling Study
Principal Investigator: Irving, Elaine
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4574. The objective is to sample benthic invertebrates in Jackfish Bay (exposure area) and Kam Bay (reference area), to confirm benthic results from 2018 and determine if treated Con Mine effluent is affecting the benthic community in Jackfish Bay. Benthic invertebrate samples will be collected at five stations in each ...


Fate of heavy metals in lagoon and wetland wastewater treatment systems and quantification of relative impacts to downstream aquatic systems
Principal Investigator: Jamieson, Rob
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4511. The overall objective of this study is improved understanding of heavy metals in Sewage Disposal Facilities (SDFs) and Solid Waste Disposal Facilities (SWDFs) in the NWT. The proposed study aims to answer the following questions: 1) What is the existing treatment capacity of SDFs in NWT for heavy metals? 2) Are SDFs “...


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: This licence has been issued for the scientific research application No.4564. 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; 2) are fires becoming more fre...


Transitioning of permafrost to wetland and implications for biomass gains and losses
Principal Investigator: Chasmer, Laura E
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4527. The objectives are to: 1) Compare the distribution of tree and shrub biomass within accessible areas in the Taiga Shield and Taiga Plains landscapes using lidar remote sensing, and by developing tree and shrub vegetation biomass models from field data; 2) Characterize and compare non fire-disturbed patterns of veget...


ABoVE Permafrost Dynamics Observatory
Principal Investigator: Miller, Charles E
Licensed Year(s): 2019
Summary: The objective of this project is to collect physical and geophysical measurements quantifying permafrost susceptibility to ABoVE's internationally-available dataset. Researchers can access these data to bolster understanding of environmental processes and the ability to remotely-sense these on a regional scale. Airborne remote sensing missions from August 2017, 2018, and August of 2019 by NASA'...


Self-stabilization of thaw slumps
Principal Investigator: Doré, Guy
Licensed Year(s): 2019
Summary: The research team are studying the natural stabilization of thaw slumps in the aim to eventually develop adapted management strategies for infrastructure at risk. The specific objectives are to assess the variations of thaw slump stabilization across landscapes, regions, and climates; and to assess the positive and negative feedback effects controlling the natural stabilization of thaw slumps....


Reconstructing latitudinal terrestrial temperature gradients at the Cretaceous-Paleogene Boundary: testing the 'Equable Earth' hypothesis
Principal Investigator: Jerrett, Rhodri
Licensed Year(s): 2019
Summary: The research team have chosen this site in the Northwest Territories to collect coal samples from, as it contains the Cretaceous-Paleogene sandstone and iridium-anomaly that places the ages of these coals in that period. The team will access pristine coal samples by excavating the weathered rock back by 1 m (using spade and shovel). They will then sample a vertical profile by collecting coal sampl...


Impacts of wildfire and forest management on permafrost conditions and post-fire regeneration
Principal Investigator: Baltzer, Jennifer L
Licensed Year(s): 2019
Summary: The primary objective is to better understand the impact of disturbance on forest regeneration in the NWT. To this end, the team aim to evaluate the direct impacts of both forest harvesting and wildfire on tree regeneration the interaction of these two disturbances with permafrost thaw. The research team will establish new monitoring sites in the proposed Forest Management Areas and adjacent un...
