THAWPOND-NWT – Remote sensing analysis of vegetation and thaw pond colour dynamics in the continuous permafrost zone: from local to regional (Northwest Territories, Arctic Canada)
chercheur principal: Vieira, Gonçalo
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No. 5639. The goal of this research project is to better understand the characteristics of various different lakes, how their characteristics vary, as well as their potential relation to permafrost thaw events in the recent or distant past. The frequency of occurrence across space and time as well as the variability of: 1) opt...


The Great Bear Lake ice thickness and water quality observations under current and future climates (2022-2025)
chercheur principal: Kheyrollah Pour, Homa
Année(s) de permis: 2024 2023 2022
Résumé: This licence has been issued for the scientific research application No. 5677. This project aims to reconstruct trends in ice phenology using remotely-sensed and ground-based observations and collective memories of land-based and in-lake changes by communities living along the shoreline of Great Bear Lake (GBL) to characterize the interannual variability of ice formation in the lake and determi...


Rapid Creek Formation
chercheur principal: Gadd, Michael
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No.5577. The objective of this project is to better understand the physical, chemical, and biological controls of the Rapid Creek Formation by collecting and analyzing samples (through fieldwork) and developing a new sequence stratigraphic framework for the purpose of uncovering its potential and enabling the identification of...


Inuvik to Tuktoyaktuk Highway Metal Chemistry
chercheur principal: Gammon, Paul R
Année(s) de permis: 2023 2022 2021
Résumé: This licence has been issued for the scientific research application No.5551. The overall objective of the research is to eventually determine the environmental chemistry of the elevated metal concentrations, which will in turn determine the environmental risk that these measured concentrations pose (i.e. will answer, at least in part, the questions: do these sites require remediation, and in w...


Monitoring the impacts of permafrost thaw on water resources at Scotty Creek, NWT
chercheur principal: Quinton, William L.
Année(s) de permis: 2024 2023
Résumé: This licence has been issued for the scientific research application No.5521. The long-term objective of this research programme is to improve the understanding, parameterisation and prediction of water flow and storage processes in peatland-dominated, thawing, discontinuous permafrost. Over the next 5 years, significant progress toward this long term objective will be made through the follo...


Hydrology of High Latitude Watersheds
chercheur principal: Marsh, Philip
Année(s) de permis: 2023 2022 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Résumé: This licence has been issued for the scientific research application No.5496. The objectives of this project are: 1) to develop improved understanding of, and ability to predict, snowcover formation and melt, as well as stream discharge in northern regions; 2) consider the integrated effect of climate on vegetation, snow, permafrost, streamflow, and lakes; and 4) develop improved predictive mod...


Aquifer Mapping of the Hay River and Kakisa/Cameron Hills Transboundary Region in Alberta & Northwest Territories
chercheur principal: Palombi, Dan
Année(s) de permis: 2024 2023
Résumé: This licence has been issued for the scientific research application No.5382. There is limited knowledge of groundwater resources in the Alberta-Northwest Territories transboundary basins. Hydrogeological information to delineate transboundary groundwater is scarce and aquifers in this area have not been fully defined and mapped. The primary and long-term goal of the research project is to cont...
