Long-term changes in climate and fire activity in the Mackenzie Delta region
chercheur principal: Porter, Trevor
Année(s) de permis: 2023 2022
Résumé: This licence has been issued for the scientific research application No.5487. During the 2022 field season, the main objectives are to collect tree-ring and wedge-ice samples that will be studied to better understand changes in climate over the last 11,700 years and to identify lake sites that will be suitable for lake-sediment coring in the early spring field season. This fieldwork will focus ...


Mapping, monitoring and modelling permafrost change in the NWT
chercheur principal: Kokelj, Steve V
Année(s) de permis: 2024 2023 2022 2021
Résumé: This licence has been issued for the scientific research application No.5473. The primary objectives of this research are: 1) to develop and test new methods of characterizing permafrost and monitoring permafrost landscape change with a focus on the Beaufort Delta, central Mackenzie Valley and North Slave regions; 2) mapping sensitive permafrost terrain across NWT by integrating expert assessme...


Instrumentation and thermal monitoring of the Gunghi Creek Arch Bridge Replacement
chercheur principal: Beddoe, Ryley
Année(s) de permis: 2024 2023 2022
Résumé: This licence has been issued for the scientific research application No.5466. The objectives of this research are to: 1) monitor the thermal regime of the embankment, arch, piles and road subgrade post the construction of the arch replacement; 2) use measured ground temperatures to calibrate numerical models for understanding and predicting bridge, road and embankment stability; 3) analyze mult...


Invertebrate paleoecology of the Mackenzie River uplands region
chercheur principal: Medeiros, Andrew
Année(s) de permis: 2023 2022
Résumé: This licence has been issued for the scientific research application No.5455. To examine the effects of flooding and permafrost changes on the ecological function and structure of differing lakes in the Mackenzie River uplands region. The research team will drive to sites along the Inuvik-Tuktoyaktuk Highway to collect 1 litre water samples from a small boat. The research team will be using...


Measuring and simulating permafrost thaw
chercheur principal: Gruber, Stephan
Année(s) de permis: 2023 2022 2021
Résumé: This licence has been issued for the scientific research application No.5425. The objectives of this project are to understand: 1) how permafrost differs in temperature and chemical/physical characteristics from place to place; 2) how these different types of permafrost react to change (climate/disturbance); and, 3) which future changes in permafrost are likely and which are less likely based o...


Watershed-scale geomorphic response to climate change in the Aklavik Range, NWT
chercheur principal: Strauss, Justin Vincent
Année(s) de permis: 2024 2023 2022
Résumé: This licence has been issued for the scientific research application No.5411. or this latest phase of research, the research team propose to integrate field observations, geochemical techniques, and historical remote sensing analysis to quantify the rates and processes by which sediment is generated from bedrock and transported downslope via hillslope and river processes under a changing climat...


Quantification of carbon fluxes and ecosystem characteristics in permafrost regions with a special focus on the impact of degradation processes
chercheur principal: Goeckede, Mathias
Année(s) de permis: 2022
Résumé: This licence has been issued for the scientific research application No.5279. As part of the European Research Council (ERC)-synergy project Q-Arctic, the research team plan to investigate biogeochemical and biogeophysical processes along transects following landscape gradients. Such gradients include natural variability within heterogeneous permafrost landscapes (e.g. a transect from dry uploa...


CoMet 2.0 Arctic
chercheur principal: Fix, Andreas
Année(s) de permis: 2022
Résumé: This licence has been issued for the scientific research application No.5211. This project will use aircraft-based instruments using both remote-sensing and in-situ-techniques to carry out measurements of methane and carbon trace gases and tracers related to their emissions. The results will help to better understand the global methane and carbon cycle. This mission makes use of the German r...


Development of a Biological Monitoring Program to Detect Change in Stream Health Along the Dempster–Inuvik–Tuktoyaktuk-Corridor
chercheur principal: Musetta-Lambert, Jordan
Année(s) de permis: 2022 2021 2020 2019
Résumé: This licence has been issued for the scientific research application No.5323. The purpose of this project is to establish a stream biomonitoring program along the Dempster–Inuvik–Tuktoyaktuk-Corridor to understand the current environmental conditions associated with past and newly developed road infrastructure. The research team will establish a stream biomonitoring program for the Inuvik to Tu...


Measuring surface displacement using winter SAR
chercheur principal: Rabus, Bernhard
Année(s) de permis: 2023 2022
Résumé: This licence has been issued for the scientific research application No.5270. The objective of this research is to determine the accuracy of existing physical models of the InSAR (Interferometric Synthetic Aperture Radar) dry snow signal; and, if the snow signature can be removed to enable accurate measurement of heave from winter refreezing in the active layer. There are currently three res...
