Impacts of wildfire on runoff response and downstream water chemistry in a region with rapid permafrost loss
Principal Investigator: Olefeldt, David
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5892. Objective summary: To assess the effect of wildfires on changes in water quality in the Dehcho and South Slave region, which are affected by runoff from peatlands (containing e.g., organics, nutrients, and mercury/methylmercury), which are already experiencing increased permafrost thaw due to climate change. Synop...


The export of terrigenous dissolved organic carbon from boreal terrestrial ecosystems to the Arctic Ocean and its vulnerability to environmental change
Principal Investigator: Fichot, Cedric
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No. 5897. The primary objective of this funded project is to develop a sophisticated model that can simulate the mobilization, transport, transformations, and export of tDOC from the Mackenzie River watershed to the Arctic Ocean. The model will be used to simulate the transfer of tDOC during the past two decades and for plausi...


Impact of wildfire and forest management on permafrost and post-fire regeneration
Principal Investigator: Baltzer, Jennifer L
Licensed Year(s): 2024 2023 2022 2021 2020 2019
Summary: This licence has been issued for the scientific research application No. 5902. This project has two main objectives: 1) To monitor the recovery of NWT forests following wildfire to better understand post-fire changes on forest composition and ground vegetation 2) To develop baseline information about proposed forest management areas to support assessment of harvesting impacts on these areas...


Lakes as sentinels of environmental change in discontinuous permafrost peatlands
Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No. 5774. Understand and predict how lakes in discontinuous permafrost peatlands are changing in response to climate warming and loss of permafrost. Field activities will focus on three regions/objectives: (1) Inferring long-term environmental change in the Five Fish Lakes (Lue Túé Sulái) – We will collect short (~30-50 ...


The frontline of permafrost thaw: a transect of eddy covariance towers across the southern Taiga Plains to better understand changing regional carbon and water budgets
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2024 2023 2022 2021 2019 2018 2018 2017 2016 2015
Summary: This licence has been issued for the scientific research application No. 5890. Through this project my research group will address the following objectives: What is the net effect of permafrost thawing induced biophysical and biogeochemical feedbacks to the climate system? How do these two types of feedback differ between the sporadic and discontinuous permafrost zones? Is the reported decrease...


Scotty Creek 2.0: how interaction between rapidly thawing permafrost and wildfire affect peatland complex trace gas exchanges
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No. 5889. The objective of the research project is to elucidate the change in the atmospheric carbon balance of thawing permafrost regions post-disturbance.The impact of disturbances such as fire, especially in conjunction with permafrost thaw, are still not well understood. By installing a new 15-m eddy covariance tower at Sc...


Interviewing local news reporters
Principal Investigator: Nagel, Tyler
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5632. For the fieldwork proposed by this ethics application, the research question is: "What is the information ecology in Canadian communities served (and not served) by professional journalism?" The immediate goal of the proposed research is to describe, understand, and interpret the information ecosystems in rural areas...


Elections NWT Survey (2024)
Principal Investigator: Goodman, Nicole
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5900. To provide Elections NWT with feedback regarding voter experiences with online voting and how the wildfires may have changed uptake. The survey will be programmed and hosted using the Brock University Qualtrics platform. All persons who voted online will be sent a recruitment email inviting them to take a 5-minute...


Secondary Analysis of the Addiction Recovery Experiences Survey Data
Principal Investigator: Denning, Bryany
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5856. This analysis will seek to provide more detailed insights into recovery supports and services in the Northwest Territories. Through secondary analysis of the data collected during the Addiction Recovery Experiences Survey, we will explore the role of social support in addiction recovery, examine whether there are de...


Geothermal potential of the Southern Mackenzie Region
Principal Investigator: Raymond, Jasmin
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5830. The research project aims to evaluate the geothermal potential in the communities of Hay River, Entreprise, Fort Entreprise and Kakisa in NWT where a geothermal gradient favourable to geothermal resource development is known to exist and can exceed 40°C/km. Giving those diesel dependent communities access to clean en...
