Tlicho All-Season Road
Principal Investigator: Walmsley, Caroline
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4587. The objective is to conduct monitor to ensure that the project is overall compliant with the environmental permit and approval conditions and requirements. Water monitoring at water crossing locations will be required for any in-water construction and where there is potential for entrainment of sediments. This inc...


Radar Satellite Observations of Lake Ice Breakup and Freeze-up
Principal Investigator: Drouin, Hugo
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4588. This project aims to evaluate and develop the utility of Canada’s future RADARSAT Constellation Mission (RCM) (launch June 2019) 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 ...


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 ...


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'...


NASA ABoVE Airborne Campaign 2019
Principal Investigator: Miller, Charles E
Licensed Year(s): 2019 2018 2017
Summary: This licence has been issued for the scientific research application No.4499. This airborne field campaign will link studies conducted on the ground with data collected through satellite remote sensing, enabling a deeper understanding of the vulnerability and resilience of these ecosystems, and how people within and beyond this region are responding to change. The ABoVE airborne campaigns can p...


NSERC Canadian Lake Pulse Network: more than 660 Canadian lakes sampled over three summers.
Principal Investigator: Huot, Yannick
Licensed Year(s): 2019
Summary: The objective of this project is to evaluate and compare complex and abundant lake ecosystems. This will be addressed through answering these 4 core questions: 1. Where, by how much and why Canadian lakes have changed during the last centuries? 2. How do taxonomic, molecular and biochemical features of planktonic, benthic and microbial communities change with lake alteration and which ones can...


Lake and River Ice Fieldwork in support of PermASAR data analysis
Principal Investigator: van der Sanden, Josephus J
Licensed Year(s): 2019
Summary: This project aims to undertake fieldwork in the context of the PermASAR winter campaign. The data collected will support the evaluation and development of radar satellite Earth observation (EO) technology for application to the mapping of river and lake ice processes and properties. The research team expect the fieldwork to take place over a period of two to three weeks in the months of Februar...


Quantifying permafrost thaw
Principal Investigator: Gruber, Stephan
Licensed Year(s): 2019 2018 2017 2016 2015
Summary: The objectives of this research are: 1) to understand better how permafrost differs in temperature and chemical/physical characteristics from place to place; 2) to understand how these different types of permafrost respond to change (climate/disturbance); and, 3) to understand which future changes in permafrost are likely and which are less likely based on computer simulations. High-quality mea...
