To what extent will nitrogen limit Canadian boreal forest growth and the terrestrial carbon sink under global change?
chercheur principal: Kou-Giesbrecht, Sian
Année(s) de permis: 2025 2024
Résumé: This licence has been issued for the scientific research application No. 6084. The overarching objective of this research is to understand the extent to which nutrients will limit forest growth and terrestrial carbon sequestration in Canadian boreal forests and to improve how this is represented in climate change models. These climate change models can then be used to understand the impacts of ...


Maintaining permafrost ecosystem data series at Trail Valley Creek
chercheur principal: Boike, Julia
Année(s) de permis: 2025 2024
Résumé: This licence has been issued for the scientific research application No. 6102. The objectives for this expedition are to collect data from the soil moisture and temperature sensors that we installed during the expedition in 2022 and to install additional sensors near the existing ones. Additionally, we plan to maintain and upgrade existing, long-term observations at the Trail Valley Creek site....

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...


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...


The Hidden Image of Thawing Permafrost: Mapping Subsurface Properties and Taliks with Remote Sensing (HIT Permafrost)
chercheur principal: Grünberg, Inge
Année(s) de permis: 2022
Résumé: This licence has been issued for the scientific research application No.5196. The goal for this expedition is to collect ground-truth data for two prior airborne campaigns conducted in 2018 and 2019. The data obtained from radar remote sensing of the area around Trail Valley Creek represent a complex signal from the vegetation, active layer, and permafrost. Based on prior field expeditions, the...


Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT
chercheur principal: Smith, Sharon S
Année(s) de permis: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Résumé: This project continues the on-going monitoring program of permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT. The objectives are: 1) To provide baseline knowledge of permafrost and terrain conditions (specifically ground temperature and permafrost active layer thickness) and improve characterization of terrain sensitivity in the Macken...


Permafrost, river, and groundwater inputs of trace elements and nutrients to the Mackenzie River estuary
chercheur principal: Charette, Matthew
Année(s) de permis: 2016
Résumé: The objectives are to measure a suite of trace elements and isotopes (TEIs) in the active layer and permanently frozen layer of permafrost cores sampled near the Mackenzie River, and to compare these concentrations to those observed in submarine groundwater discharge and Mackenzie River discharge in order to determine whether permafrost-associated TEIs are being transported to the coastal Arctic. ...


Community based permafrost and active layer monitoring program
chercheur principal: Yoshikawa, Kenji KY
Année(s) de permis: 2013
Résumé: Uniform permafrost and ground surface temperature measurements are one of the more important databases for long-term climatic study as well as remote sensing ground truthing data. Consistency in sensor depth, casing and drilling methods helps in comparison of the spatial and temporal distribution of the permafrost and seasonal conditions. The proposed partnership with the schools aids continuous m...


Near-surface ground ice in Mackenzie Delta region
chercheur principal: Kokelj, Steven V
Année(s) de permis: 2004 2003 2002 2001 2000 2000 1999
Résumé: The proposed research will investigate the physical and chemical characteristics of the near-surface ice-rich zone in sediments of the Mackenzie Delta area. The goals of the research are to investigate the relationship between ice-rich permafrost and fo...
