Licensed Year(s): 2025 2024
Summary: 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 ...

Principal Investigator: Boike, Julia
Licensed Year(s): 2025 2024
Summary: 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....

Principal Investigator: Grünberg, Inge
Licensed Year(s): 2022
Summary: 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...

Summary: The active layer is the earth overlying permafrost that thaws from the surface and re-freezes each year, and it responds to climate change. Active layer thickness influences vegetation and soil conditions, potentially influencing hunting, forestry, etc. and it’s, thickness, texture and moisture content affects foundations. Changes in the active layer and thaw depth can contribute to slope instabil...

Principal Investigator: Biggar, Kevin
Licensed Year(s): 2006 2005
Summary: Since the 1970s, the oil and gas industry has drilled at least nineteen exploratory wells in the Kendall Island Bird Sanctuary. Observations at associated drilling mud-sumps have been made; however, there remains a paucity of field data describing site conditions. It is also appreciated that construction of the proposed Mackenzie Valley pipeline will stimulate the development of Niglintgak and Tag...

Principal Investigator: Nguyen, Thai-Nguyen
Licensed Year(s): 2006 2005
Summary: The objective of this research is to determine the spatial correlation between surface properties and active-layer thickness. Six sites have been established across the treeline, between Inuvik and Swimming Point. At each site, shallow temperature cables are installed in the active-layer and near-surface permafrost and air temperatures are monitored by data logger. During this project, the res...

Principal Investigator: Povey, Andrew
Licensed Year(s): 2005 2004 2003 2002
Summary: The 2005 terrestrial studies in the Inuvialuit Settlement Region (ISR) will include vegetation classification, rare plant surveys, and landform, soil and permafrost investigations. The studies will be conducted by three- or four-person crews supported by helicopter and based in Inuvik. A local assistant will be hired as part of each survey team. Air calls from a helicopter will be used to map ...

Principal Investigator: Kokelj, Steven V
Licensed Year(s): 2006 2005
Summary: Since the 1970's, the oil and gas industry has drilled at least 19 exploratory wells in the Kendall Island Bird Sanctuary (KIBS), but there is a shortage of field data describing environmental conditions at the well-sites and drilling-mud sumps. In Marc...

Summary: The primary objective of this project is to develop improved understanding of the fluxes of water and energy in northern regions, and to develop improved computer models of these processes. The Trail Valley Creek site will be accessed by helicopter and s...

Licensed Year(s): 1980
Summary: To conduct a low level (2000 ft. above groud level) a high level (30,000 ft. A.G.L.) aerial surveys of the reindeer rangeland. Ground truthing will also take place along with collection of plants, soil and water made to complete the study....
