Continuation of the Gordon Lake Assessment Project
Principal Investigator: Doucet, Michael
Licenced Year(s): 2016 2015
Summary: The primary objective of this research program is to determine the environmental and physical conditions of nine sites in the Gordon Lake region. This research will include the identification and quantification of environmental impacts in soil, sediment, surface water and groundwater. Samples of biota (e.g. Hyalella) may be collected at certain sites during the field program. The potential for...


Permafrost Thaw and Implications for the Cycling of Radionuclides in the Canadian North
Principal Investigator: Bond, Matthew J
Licenced Year(s): 2016
Summary: The objective of this research is to determine whether permafrost thaw in the Canadian north is resulting in the release of historic radionuclides to surface waters. The results of this study will be incorporated into a larger model of radionuclide fate and transport in the Canadian north. Field work will involve sampling surface water (triplicate 500 mL samples), groundwater seepage (triplicat...


Integrated Regional Impact Study of the Coastal Western Canadian Arctic
Principal Investigator: Levesque, Keith R
Licenced Year(s): 2016
Summary: The central aim of the ArcticNet marine-based research program is to study on a long-term basis how climate induced changes are impacting the marine ecosystem, contaminant transport, biogeochemical fluxes, and exchange processes across the ocean-sea ice-atmosphere interface in the Canadian Arctic Ocean. The knowledge generated from this multi- year program is integrated into regional impact studie...


Tundra Mine Remediation Risk Assessment
Principal Investigator: Corrin, Natasha
Licenced Year(s): 2016
Summary: The overall objective of the Tundra Mine risk assessment is to facilitate project closure by determining if there are any residual risks to human health or ecological receptors, including aquatic life, associated with the proposed tailings remediation. If any risks remain, the goal is to provide recommendations for risk management. In support of the risk assessment, and in order to collect baselin...


The influence of forest fires on metal deposition to lakes and peatlands in the North Slave Region, NWT
Principal Investigator: Chetelat, John
Licenced Year(s): 2016
Summary: The research team will use natural environmental archives (lake sediment and peat cores) to characterize the forest fire history in the study region and test the relationship between fire events and metal accumulation over recent centuries. Study sites will be selected along a gradient of recent forest fire activity with some study sites located in areas of the latest burns (2014-15) to examine th...


Thetis Bay Bathymetric Survey and Benthic Sampling
Principal Investigator: Wolf, Calvin
Licenced Year(s): 2016
Summary: The objective of this project is to document the physical condition of the seabed lease following the removal of the Tarsiut Caissons. The project also includes sampling benthic populations in the disturbed and undisturbed areas of the lease. This information can be used as a benchmark for possible future study of the effects of natural processes in restoring the footprint of the caissons. A bathy...


Water Ecosystem Monitoring using Earth Observations
Principal Investigator: Chamberland, Joseph
Licenced Year(s): 2016 2015
Summary: The research project Water Ecosystems Monitoring using Earth Observation aims to define an Earth Observation (EO) driven monitoring program to provide information towards monitoring environmental indicators of northern ecosystem health. Once the project is done information on water indicators including water temperature, suspended sediment concentrations, water levels, and ice quality and will be ...


The effects of fire on diverse aquatic ecosystems of the NWT
Principal Investigator: Tank, Suzanne E
Licenced Year(s): 2016
Summary: 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...


Hydrological and contaminant studies in the Marian Watershed, NWT, to enhance community-based cumulative effects monitoring
Principal Investigator: Wolfe, Brent BBW
Licenced Year(s): 2016
Summary: While water and sediment quality monitoring in areas of industrial developments is an integral part of water management programs to ensure protection of ecosystems, absence of long-term measurements can make it challenging to define reference conditions effectively. As a contribution to the Marian Watershed Stewardship Program (MWSP), this research uses paleolimnological approaches to establish ba...


The ecology and paleoecology of benthic macroinvertebrates in the Mackenzie Delta region
Principal Investigator: Quinlan, Roberto
Licenced Year(s): 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...
