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 ...


Implications of climate change and permafrost thaw on carbon dynamics and biodiversity in the lower MRB watersheds
chercheur principal:
Année(s) de permis: 2024
Résumé: This licence has been issued for the scientific research application No. 5507. The objectives of this research are to: 1) Assess the spatial and temporal distribution of particulate and dissolved nutrients/carbon along a large- and small-scale latitudinal gradients in the MRB (I.e. Slave River, Great Slave Lake, Mackenzie River, Laird River, Peel River, smaller headwater streams); Correlate...


Quantifying carbon fluxes and budgets of boreal forest-tundra landscapes under the influence of rapidly changing permafrost regimes
chercheur principal:
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 ...


Large wood transport in the Mackenzie River Basin
chercheur principal:
Année(s) de permis: 2019
Résumé: The objectives of this project are to understand the dynamics of large wood transport in the Mackenzie River and Delta by identifying the locations of wood sources and deposition, and quantifying the amount of wood that reaches the delta and the processes affecting wood transport. Using this knowledge, the research team can make estimates of carbon transport to the Arctic and improve global models...


Recent changes in carbon source-sink relationships and greenhouse gas emissions in forest and peatland ecosystems along the Mackenzie Valley region of Canada
chercheur principal:
Année(s) de permis: 2011 2010 2009 2008 2007
Résumé: The objectives of this research project are to: 1. map and assess changes in the distribution and composition of forest and peatland ecosystems due to climate changes; 2. estimate carbon storage (and variation) in boreal to arctic ecoregions of the Mackenzie valley; and 3. assess interannual and seasonal variations and key processes controlling carbon dioxide (CO2) and methane (CH4) dynamics. ...


Climate Geochemistry
chercheur principal:
Année(s) de permis: 2005 2004
Résumé: The purpose of this study is to collect river waters to determine the concentrations of dissolved organic carbon, particulate organic carbon, and nutrients, including nitrate, phosphate and silicate, and to examine their temporary variations related to c...
