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...

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. ...

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...

Tundra-Atmosphere Carbon Exchange
chercheur principal: Lafleur, Peter M
Année(s) de permis: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2007 2005 2004
Résumé: The aim of this project is to study how greenhouse gases are exchanged between tundra and atmosphere. This will be related to environmental variables, such as soil and weather, to understand how climate change will impact the land, and in turn how these impacts might influence the climate. Previous measurements indicate that tundras near the Daring Lake Research Station are a net sink for CO2 d...

Fire, carbon budget and climate change
chercheur principal: Wein, Ross
Année(s) de permis: 1993
Résumé: The research team will be examining areas of permafrost south of Inuvik and near Hay River in order to assess the rate of loss of permafrost as a result of the warming in climate over the past twenty years. The loss in permafrost may be speeded up following a local fire. The wetlands that replace these areas of permafrost could lead to a greater production of methane (one of the gases that contr...
