Three-Dimensional multi-methodological Investigation of Retrogressive Thaw Slumps in the Mackenzie Delta region (3DIRTS)
chercheur principal: Kunz, Julius
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No. 5655. This project aims to investigate the three-dimensional subsurface structures in the vicinity of active retrogressive thaw slumps and their relationship to spatio-temporal slump-development. The number and activity of retrogressive thaw slumps have increased during the last decades due to climatic, hydrologic and ther...


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...


Multi-methodological three-dimensional investigation of open- and closed-system Pingos in northwestern Canada (Pingo3D)
chercheur principal: Kneisel, Christof
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No. 5654. This research project aims to investigate the three-dimensional internal structure of pingos in the Mackenzie Delta Region. The focus is on small-scale heterogeneities and a detailed delineation of ice-rich or unfrozen areas within, underneath and in close proximity to different pingos. High-resolution, three-dimensi...


Evaluating earthquake geohazard using the Western Arctic Regional Network of Seismographs (WARNS)
chercheur principal: Schaeffer, Andrew
Année(s) de permis: 2024 2023 2022
Résumé: This licence has been issued for the scientific research application No. 5616. This project aims to better characterize tectonic activity and evolution across the study region through improved monitoring of earthquakes and GPS motions. Using a temporary network of seismometers, the research team will produce an updated catalogue of earthquakes targeting more precise locations, depths, frequency...


Effects of permafrost thaw and vegetation shifts on carbon and mercury cycling
chercheur principal: Wild, Birgit
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No.5564. The main goal of the project is to understand how gradients in tundra vegetation and permafrost thaw affect soil carbon and mercury cycling. This will allow the research team to assess how permafrost thaw and changes in vegetation in a warmer climate could alter future carbon dioxide fluxes and impact mercury cycling ...


Understanding the cumulative impacts of beaver activity on stream health in the Inuvialuit Settlement Region
chercheur principal: Musetta-Lambert, Jordan
Année(s) de permis: 2024 2023
Résumé: This licence has been issued for the scientific research application No. 5641. The broad research question is: How will beaver activity in the tundra impact aquatic ecosystem health? This research project will answer this broad question by addressing the following specific objectives and questions: Generate an understanding of beaver activity impacts on aquatic food webs in tundra streams. Que...


Perma-X Airborne Campaign 2023
chercheur principal: Grosse, Guido
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No. 5656. The objective is to conduct airborne surveys at 3300ft (1000m) altitude to collect high-resolution aerial images and LiDAR elevation data that can be used to describe and quantify rates of permafrost thaw, coastal erosion, thaw slumping, lake change, and vegetation change. Daily survey flights (depending on cloud-fre...

Résumé: This licence has been issued for the scientific research application No. 5635. The objectives are: To establish the patterns of occupancy of beavers along the Inuvik-Tuk highway. To establish the patterns of past occupancy of beavers along the Inuvik-Tuk highway. To coproduce monitoring methods for ongoing beaver monitoring and research with community researchers. To develop methods for ide...


BARIN-beavers and socio-ecological resilience in Inuit Nunangat-community based mapping and Indigenous knowledg research
chercheur principal: Wheeler, Helen
Année(s) de permis: 2024 2023
Résumé: This licence has been issued for the scientific research application No. 5640. Objectives: To address changing beaver population and the impacts on lakes and streams, fish and communities and wellbeing, including: a) research with communities to develop an approach for mapping beaver occupancy using photo, video and drones b) research in to the impacts of beavers on people c) research in...


Landscape Change in the Western Arctic
chercheur principal: Lantz, Trevor C.
Année(s) de permis: 2024 2023
Résumé: This licence has been issued for the scientific research application No. 5594. The main goal is to use remote sensing (Landsat, QuickBird, InSAR, Airphotos, and Remotely Piloted Aerial Systems (RPAS)) to document regional landscape change (tundra fire, infrastructure, saline flooding, slumps, subsidence, vegetation change, lake drainage / expansion, etc.). 2) Use field sampling and monitoring t...
