The objective of this study is to determine the effect of fire on water quality within the southern Northwest Territories landscape. The research team will work across the Taiga Plains and Taiga Shield Ecoregions, because it is believed that differences in landscape between these regions will affect the catchment response to fire. The research team will also target catchments with variable permaf...

The project team intend to study carbon cycling in peatland catchments, in order to determine whether the interactions between wildfire and permafrost thaw causes increased release of greenhouse gases from peatlands and aquatic ecosystems to the atmosphere, and thus cause amplified climate change.
Given the overall objective of the project, the research team intend to address 5 research questi...

Thaw slumps are one of the most dramatic thermokarst features in permafrost regions. The number of thaw slumps on Banks Island has more than tripled in recent decades and it is likely that this change is altering terrestrial and aquatic ecosystems. This multidisciplinary research project investigates the short- (1960s-present day) and long-term (Medieval Warm Period to today) impacts of permafrost...

The objective of this research is to revisit fixed sample stations at near-field, mid-field and far-field sites over the course of the year in an effort to determine any seasonal variation that may exist and confirm impact predictions.
The AEMP Version 3.5 will consist of the following components; Dust Deposition; Effluent and Water Chemistry; Indicators of Eutrophication; Sediment Chemistry; P...

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. Patterned ground marked by ice-wedge polygons is formed by freezing and thawing of the soil, which forms cracks into which ice can spread and cause the soil to uplift. These processes have effects on the hydrology and water chemistry of a...
Principal Investigator:Wilcockson, John B Licenced Year(s):
To collect baseline aquatic data in advance of the development of the Prairie Creek Mine. The study will be part of the Aquatic Effects Monitoring Program (AEMP) and will satisfy the requirements of the federal Environmental Effects Monitoring (EEM).
The description below is a summary of the planned methodology. Most work will be carried out on Prairie Creek; however, sampling will also be con...

The Tlicho Lands Moratorium was lifted in June 2013, and development pressure is expected to increase on Tlicho Lands. As Tlicho Lands are in relatively pristine condition, the intent of this study is to begin to collect baseline data at sites prioritized by community members away from specific project footprints in order to analyze the cumulative impacts of development, climate change, and increa...

Recent increases in fish mercury concentrations in the Mackenzie River basin are an environmental and human health concern. In several cases, new fish consumption advisories have been released by the NWT Health and Social Services for some lakes in the NWT. It remains unclear what processes are driving these trends in metal bioaccumulation. Two dominant hypotheses are: 1) new sources of long-range...
Principal Investigator:Kramer, Tara Licenced Year(s):
The primary objective of this research program is to collect baseline data on:
1) water chemistry, limnologic profiles, sediments, plankton, benthic invertebrates and aquatic habitat; and,
2) fish presence and collection of fish tissue for metal analysis.
The Aquatics field program will be conducted in the spring of 2013. During the field program, the following samples will be coll...

The objective of this study is to describe the terrestrial and aquatic environment in the Yellowknife River between Prosperous Lake and Bluefish Lake as per the Fisheries Authorization and the Water Licence. This may include investigating vegetation, water quality, benthic invertebrate populations, and fish. The results will be used to determine the most suitable means of fish habitat compensation...
