Carbon and trace metal transfers in the Mackenzie Delta region
chercheur principal: Hilton, Robert G
Année(s) de permis: 2024 2023
Résumé: This licence has been issued for the scientific research application No. 5924. The ultimate aim of this research is to transform understanding of how greenhouse gas emissions from rivers will impact the future trajectory of atmospheric CO2 and CH4 concentrations. Two key research objectives have been identified to address major research gaps in this carbon flux: Objective 1: Conduct river-bo...


Effects of snowpack temporal and physical properties affect wintertime carbon fluxes in Arctic landscapes
chercheur principal: Rutter, Nick
Année(s) de permis: 2024
Résumé: This licence has been issued for the scientific research application No. 5822. The objectives of this project are: (1) To develop, deploy, and refine low-cost sensors to measure green house gas (GHG) concentrations. (2) To identify GHG concentration patterns within snowpacks at a landscape scale (1 to 10 square km). (3) To optimise winter carbon cycling in climate models, and scale up simula...


Studies of greenhouse gas release and associated environmental processes with thawing permafrost in the Inuvialuit Settlement Region
chercheur principal: Morse, Peter D
Année(s) de permis: 2024
Résumé: This licence has been issued for the scientific research application No. 5797. The goals of this multi-year-long project are to assess greenhouse gas (methane and carbon dioxide) release from warming permafrost and tundra lakes in the ISR and to study associated carbon dynamics and microbiological processes, including the release of mercury to the environment. The first year of field activit...


Arctic Expedition
chercheur principal: Cherrak, Marion
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No. 5623. This project will be supervised by UNIGE, Geneva University and conducted onboard by Noémie Planat, a PhD student at McGill University. This study will continuously monitor environmental data (greenhouse gasses (carbon dioxide and methane) and standard oceanographic parameters in surface water/water column, and the p...


Electric Vehicle and Smart Heating Opportunities in Yukon and NWT
chercheur principal: Collier, Joe
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No.5529. The objective is to identify these technical obstacles within specific neighborhoods that anticipate high rates of EV and smart heating unit adoption. We will model these neighborhoods in high detail and present our stakeholders with a suite of possible solutions to any encountered challenges. The Yukon portion of ...


Studies of greenhouse gas release and environmental processes associated with thawing permafrost in the Inuvialuit Settlement Region
chercheur principal: Morse, Peter D
Année(s) de permis: 2023 2022 2021
Résumé: This licence has been issued for the scientific research application No.5500. The goals of this multi-year-long project are to assess greenhouse gas (methane and carbon dioxide) release from warming permafrost and tundra lakes in the Inuvialuit Settlement Region (ISR) and to study associated carbon dynamics and microbiological processes, including the release of mercury to the environment. ...


Quantifying carbon fluxes and budgets of boreal forest-tundra landscapes under the influence of rapidly changing permafrost regimes
chercheur principal: Sonnentag, Oliver
Année(s) de permis: 2022 2021 2019 2018 2017 2016 2015 2014 2013
Résumé: This licence has been issued for the scientific research application No.5220. The project of the present application is the continuation of year-round eddy covariance measurements of carbon, water and energy fluxes at Trail Valley Creek and Havikpak Creek, established in 2013. The key methodology is tower-mounted micrometeorological measurements around the eddy covariance technique using an ...


Permafrost thaw slumps, sediment dynamics and ecosystem health of upland tundra lakes within the western Canadian Arctic
chercheur principal: Droppo, Ian
Année(s) de permis: 2020
Résumé: This licence has been issued for the scientific research application No.4759. The overall objective of this research is to assess the permafrost thaw slump erosion and transport of its sediment by rainfall/runoff to depositional zones within Arctic tundra lakes. To achieve this, we will link a rainfall simulator with an annular flume (to simulate lake currents) located in the Hydro-ecology Moni...


Permafrost carbon fluxes
chercheur principal: Pumpanen, Jukka S
Année(s) de permis: 2019
Résumé: The field work in Trail Valley Creek and Inuvik aims to study: 1) how catchment characteristics, such as vegetation and soil properties, control the amount and quality of aquatic dissolved organic matter (DOM) and its microbial degradability, and 2) how these factors further regulate greenhouse gas fluxes (carbon dioxide CO2, methane CH4, nitrous oxide N2O) from Arctic lakes. At the Dempster hi...


Greenhouse Gas Exchange in the Outer Mackenzie Delta
chercheur principal: Skeeter, Wesley R
Année(s) de permis: 2017
Résumé: The objective of this campaign will be to measure the emission/uptake of methane and carbon dioxide at Fish Island in the outer Mackenzie Delta over a full growing season. This data will be used to determine the carbon balance of the island, and estimate the carbon balance of the land surfaces in the outer Mackenzie Delta. Additionally, the research team will investigate factors influencing the ex...
