Summary:
This licence has been issued for the scientific research application No.5291.
The primary objective of this project is to develop a sophisticated model that can simulate the mobilization, transport, transformations, and export of Terrigenous Dissolved Organic Carbon (tDOC) from the Mackenzie River watershed to the Arctic Ocean. The model will be used to simulate the transfer of tDOC during the ...

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...

201520142013 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...

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...

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. The research team will also examine the fate of this carbon by undertaking incubation expe...

Summary:
The goal of this research project is to measure the concentration and composition of natural dissolved organic carbon in rivers along a latitudinal transect from central Alberta to southern NWT. Data on water quality will be combined with spatial data that describes the drainage basins of the sampled rivers, e.g. ecosystem composition, size, slope, recent fire impact and permafrost conditions.
