The export of terrigenous dissolved organic carbon from boreal terrestrial ecosystems to the Arctic Ocean and its vulnerability to environmental change
Principal Investigator: Fichot, Cedric
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No. 5897. The primary objective of this funded project is to develop a sophisticated model that can simulate the mobilization, transport, transformations, and export of tDOC from the Mackenzie River watershed to the Arctic Ocean. The model will be used to simulate the transfer of tDOC during the past two decades and for plausi...

Organic carbon cycle in the Mackenzie delta lakes
Principal Investigator: Lattaud, Julie
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5187. The project will study the dynamics of deltaic lake ecosystems over the past century through the application of recently developed molecular (lipid biomarker) and isotopic (radiocarbon and stable isotopes) proxies to lake sedimentary records. This will unravel the impact of old carbon input into aquatic ecosystems. Ra...

Where on Earth is fire-derived carbon stored?
Principal Investigator: Abiven, Samuel
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4956. The objective of this project are to measure the age and stock of organic carbon derived from wildfires (fire-derived carbon) in the Mackenzie River region and examine long- and short-term processes controlling the size and distribution of fire-derived carbon stocks in soils. The research team will measure fire-der...

Erosion of old organic carbon in the Mackenzie River Basin
Principal Investigator: Hilton, Robert G
Licensed Year(s): 2020 2019
Summary: This licence has been issued for the scientific research application No.4678. The research team will collect a new sample set to better quantify the carbon source, age and fate in one of the largest rivers draining the high latitudes. Based on previous work, the team have identified three priority objectives for sample collection in the Mackenzie River: 1) Collect river depth profile sediment ...

Erosion of old organic carbon in the Mackenzie River Basin
Principal Investigator: Hilton, Robert G
Licensed Year(s): 2017 2013 2011 2010 2009
Summary: The objective of this research is to better quantify the carbon source, age and fate in one of the largest rivers draining the high latitudes. The research team will sample river sediments and waters to establish temporal variability in OC source and age. The team will target high and falling flow (in June) when most sediment and water are exported. The research team will directly measure velo...

The ecology and paleoecology of benthic macroinvertebrates in the Mackenzie Delta region
Principal Investigator: Quinlan, Roberto
Licensed Year(s): 2017 2016 2015 2014 2013
Summary: This study will examine the effects of permafrost and flooding on the ecological structure and carbon exchange of contrasting lakes in the Mackenzie River Delta. Permafrost thaw in lake catchments may cause increased transport of organic carbon and dissolved nutrients to lakes with effects on the hydrology and water chemistry of lake environments. Patterned ground marked by ice-wedge polygons is f...

DOC in surface waters in the NWT; implications of a changing climate
Principal Investigator: English, Michael C
Licensed Year(s): 2015
Summary: This research focusses upon dissolved organic carbon (DOC) quantity and quality from a suite of hydrological environments underlain by discontinuous permafrost. The research looks to better understand how water quality will be influenced by a warming climate, with specific attention to DOC, by analysing historical water quality data (30 years) from three local rivers (Yellowknife, Cameron, and Mar...

Principal Investigator: Tank, Suzanne E
Licensed Year(s): 2019 2018 2017 2016 2015 2014
Summary: The objective of this study is to understand how permafrost slumping increases the mobilization of organic carbon from land to water, and the effects of this movement on stream communities. The research team will measure the concentration of stream-water organic carbon upstream and downstream of slump sites.
