DEPTHAW
chercheur principal:
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No.5561. Through ERT and PS methods, the extent and depth will be mapped to the top of ice-bearing permafrost (IBP) offshore of Tuktoyaktuk Island. On land, ERT surveys will also reveal information on permafrost characteristics like ice content, but offshore, tools can only reliably map the thickness of the unfrozen body (tali...


Impacts of permafrost thaw on land cover and downstream water quality
chercheur principal:
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No.5568. The primary objective of this project is to link long-term records of ground temperature and permafrost conditions with changes in landcover and water quality of adjacent ponds and lakes. In other words, how thawing permafrost alters terrestrial and aquatic ecosystem properties. Along the Mackenzie Valley corridor...


Tundra shrub response to climate change-exacerbated disturbances
chercheur principal:
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No.5567. This project has two primary objectives: 1) To investigate the differences in shrub productivity traits between undisturbed and disturbed tundra sites to better understand the impact of shrub expansion and disturbance on ecosystem function. 2) To investigate the impact of shrub productivity trait differences on deco...


Nuna, Work package 5: Social, cultural, and economic impacts of climate change
chercheur principal:
Année(s) de permis: 2024 2023
Résumé: This licence has been issued for the scientific research application No.5341. The expected value of this project is to respond to a community-identified need in the Hamlet of Tuktoyaktuk to better understand the social, cultural, and economic impacts of climate change in the community. Gathering information on community values, priorities and needs is necessary to inform appropriate climate cha...


Mapping for Ground Ice along the ITH
chercheur principal:
Année(s) de permis: 2024 2023 2022
Résumé: This licence has been issued for the scientific research application No.5420. The objectives of this study are to: 1) evaluate the geologic setting including geochemistry, and dating of sediments to establish a regional history of the area; 2) investigate the geologic setting of multiple buried, massive ice bodies; and 3) develop a geologic and hazards map along the Inuvik to Tuktoyaktuk Highwa...


Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT
chercheur principal:
Année(s) de permis: 2023 2022 2021 2020 2019
Résumé: This licence has been issued for the scientific research application No.5419. This project continues the on-going monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT. This phase of the project is largely data collection. Objectives are to provide baseline knowledge of permafrost and terrain conditions (specifically ground temperature and active la...


Potential Impacts of Climate Change on the levels of Poly- and Perfluoroalkyls in Country Foods and Implications for Human Health Risk
chercheur principal:
Année(s) de permis: 2022
Résumé: This licence has been issued for the scientific research application No.5313. The objectives of this study are to estimate potential future Perfluorooctane sulfonate (PFOS) concentrations in marine country foods under two climate change scenarios, and to determine dietary exposure estimates and hazard indices based on potential future concentrations and dietary intake data. The longer-term obje...


Drivers and constraints of ecological change in the western Arctic
chercheur principal:
Année(s) de permis: 2022 2021 2019 2018 2017
Résumé: This licence has been issued for the scientific research application No.5277. The objectives of this research are: 1) Use remote sensing (Landsat, QuickBird, InSAR, Airphotos, UAVs, etc.) to document regional landscape change (tundra fire, infrastructure, saline flooding, slumps, subsidence, vegetation change, lake drainage / expansion, etc.); and 2) Use field sampling and monitoring to determi...


Permafrost and climate change, western Arctic Canada
chercheur principal:
Année(s) de permis: 2022 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Résumé: This licence has been issued for the scientific research application No.5214. The objective is to continue monitoring change in ground temperatures, seasonal thaw depth (active layer), subsidence of the ground, change in vegetation, and thawing of ice wedges. The research team compare these data with the results of computer forecasts of how things may change with climate warming. The team hope ...


The annual scientific Arctic expedition onboard the Canadian research icebreaker CCGS Amundsen
chercheur principal:
Année(s) de permis: 2021
Résumé: This licence has been issued for the scientific research application No.4997. The aim of the research programs supported by the Amundsen in 2021 is to study on a long-term basis how climate induced changes are impacting the marine ecosystem, carbon cycle, contaminant transport, biogeochemical fluxes, and exchange processes across the ocean-sea ice-atmosphere interface in the Canadian Arctic Oce...
