Implications of climate change and permafrost thaw on carbon dynamics and biodiversity in the lower MRB watersheds
Principal Investigator: Reid, Thomas
Licensed Year(s): 2024
Summary: 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...


Carbon sequestration in boreal forests during regeneration process after forest fire disturbances.
Principal Investigator: Matsuura, Yojiro
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5340. Main objective of the project is to re-start and maintain study sites after two growing season without any census and sample collections. The research team will also establish additional study sites for regeneration process and soil condition monitoring (detection of permafrost table depth). The team will try again to...


Biogeochemistry of Lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No.5320. The objectives of this project are to improve the understanding of methane cycling in Mackenzie Delta lakes and how it is affected by the changing water levels and to decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine carbon and nutrient flow to the ocean. Improve un...


Quantifying carbon fluxes and budgets of boreal forest-tundra landscapes under the influence of rapidly changing permafrost regimes
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2022 2021 2019 2018 2017 2016 2015 2014 2013
Summary: 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 ...


The annual scientific Arctic expedition onboard the Canadian research icebreaker CCGS Amundsen
Principal Investigator: Merzouk, Anissa
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4997. The aim of the research programs supported by the Amundsen in 2021 is to study on a long-term basis how climate induced changes are impacting the marine ecosystem, carbon cycle, contaminant transport, biogeochemical fluxes, and exchange processes across the ocean-sea ice-atmosphere interface in the Canadian Arctic Oce...


Carbon in permafrost soils
Principal Investigator: Murton, Julian B
Licensed Year(s): 2019
Summary: The objective of the fieldwork is to collect soil samples from the active layer and near-surface permafrost. Twelve samples will be collected from coastal bluffs at Crumbling Point, and six samples from river banks beside East Channel. Soil profiles 1-2 m deep and naturally exposed by coastal, lake or river erosion will be cleared of slumped soil by spade, and described and recorded. At each si...


Large wood transport in the Mackenzie River Basin
Principal Investigator: Sendrowski, Alicia
Licensed Year(s): 2019
Summary: 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...


Permafrost carbon fluxes
Principal Investigator: Pumpanen, Jukka S
Licensed Year(s): 2019
Summary: 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...


Nunataryuk WP4: Satellite tracking of the organic matter in the Mackenzie Delta, impact of climate change on permafrost thaw
Principal Investigator: Babin, Marcel
Licensed Year(s): 2019
Summary: The specific objectives of this project are: 1) to document trends in export of coastal, riverine and subterranean dissolved and particulate organic matter and carbon into the Arctic Ocean; 2) to determine their fate and related processes (origin and age, transport, physical, chemical, and biological transformation) in coastal waters and estuarine sediment; and 3) to assess the impacts of thes...


Structure, Carbon Dynamics, and Silvichronology of Boreal Forests
Principal Investigator: Osawa, Akira
Licensed Year(s): 2019 2018 2016 2015 2013 2012 2011 2010 2009 2008 2007 2006
Summary: Objectives of the research are two-fold. First is to estimate structure, growth, and production of forest stands in northwestern Canada by applying a stand reconstruction and 3D ground-based laser techniques as well as stand measurement, aboveground litter collection, and find root sampling. Second is to examine the relationship between climate change in the high latitudinal regions and the patter...
