Characterization of permafrost cores from the Inuvik-Tuktoyaktuk Corridor, NWT, Canada
Principal Investigator: Alvarez, Alejandro
Licensed Year(s): 2020
Summary: This licence has been issued for the scientific research application No.4610. The objectives of this study are to: 1) evaluate the geologic setting including geochemistry, and radiocarbon ages to establish a regional history of the area; 2) investigate the geologic setting of multiple buried ice bodies; and 3) develop a geologic map along the southern Inuvik-Tuktoyaktuk Highway (ITH) highlighti...


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 ...


Wetland status, change, and seasonal inundation dynamics for assessing the vulnerability of waterfowl habitat within the ABoVE study domain
Principal Investigator: French, Nancy H
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4543. The overarching project goal is to characterize changes in waterfowl habitat using remote sensing approaches. The first objective is to create wetland type and surface inundation products (maps) for the Arctic-Boreal Vulnerability Experiment (ABoVE) boreal region. The second objective is to assess the efficacy of remo...


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'...


Whati Permafrost Vulnerability Mapping
Principal Investigator: Bonnaventure , Philip P.
Licensed Year(s): 2019
Summary: The goal of this project is to create a permafrost hazard/vulnerability map of the community of Whati, NT. In addition to the general map, ideal location(s) for future graveyard and residential development will be identified. The three main deliverables outlined in conversations with representatives from Whati are: suitable location(s) for future graveyard development, suitable locations(s) f...


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....
