To what extent will nitrogen limit Canadian boreal forest growth and the terrestrial carbon sink under global change?
chercheur principal:
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:
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....

The Hidden Image of Thawing Permafrost: Mapping Subsurface Properties and Taliks with Remote Sensing (HIT Permafrost)
chercheur principal:
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...


2005 Terrestrial Studies in the Gwich’in Settlement Area
chercheur principal:
Année(s) de permis: 2005 2004 2003 2002
Résumé: The 2005 terrestrial studies include vegetation mapping, rare plant surveys, rare plant mitigation planning, timber cruising, and landform, soil and permafrost investigations. All of the studies will be conducted by three- or four-person crews supported by helicopter. A local assistant will be included as part of each terrestrial survey team to assist in observing and recording data taken at surve...
