To what extent will nitrogen limit Canadian boreal forest growth and the terrestrial carbon sink under global change?
Principal Investigator: Kou-Giesbrecht, Sian
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 ...


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...


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...


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...


Short and long term effects of forest fires on the stability of carbon pools in the arctic permafrost and subarctic forests (ARCTICFIRE)
Principal Investigator: Koster, Kajar
Licensed Year(s): 2018 2015
Summary: The aim of this project is to study the short term and long term effects of different fire intensities on the decomposition of soil organic matter (SOM) in northern boreal forests under changing fire regimes. The objectives are to: 1) explore the short and long term effects of forest fires with different intensity on above- and belowground biomasses; 2) explore changes in albedo, snow depths an...


Arctic Peatland Carbon and Holocene Warm Climates
Principal Investigator: Beilman, David W
Licensed Year(s): 2013
Summary: The research team seek to understand carbon dynamics during warm climate intervals in the Arctic: the Holocene Thermal Maximum (HTM) the warmest pre-industrial interval ranging in timing from 10 ka (thousands of years before present) with maximum seasonality to 6 ka with reduced seasonality, and the Medieval Climate Anomaly (MCA) at ~1 ka with similar seasonality as today. By studying peat cores f...
