Assessing regulators' information needs to make decisions regarding cumulative effects under the MVRMA
Principal Investigator: Noble, Bram F
Licenced Year(s): 2017 2016
Summary: This project will determine what information regulators require about cumulative effects or conditions in order to make informed decisions regarding development impacts to water quality in the NWT, and whether and how that information is, or can be, provided through NWT Cumulative Impacts Monitoring Program (CIMP) or other agencies responsible for monitoring. The objectives are as follows: 1) T...


Discovery Mine (NWT) Year-10 Long-Term Monitoring Program
Principal Investigator: Montgomery, Shelagh
Licenced Year(s): 2016
Summary: The Discovery Mine long term monitoring (LTM) program has as its primary objective to verify the effectiveness of remedial measures at the site. This will be accomplished via a Geotechnical Monitoring and Visual Inspection; Terrestrial Environment Monitoring; Water Quality Monitoring, and Aquatic (fish) Monitoring. As part of the Phase II LTM for the Discovery Mine site, the program addresses i...


Understanding the potential impact of rare earth elements in aquatic systems in the NWT
Principal Investigator: McGeer, Jim
Licenced Year(s): 2016 2015 2014
Summary: The objectives of this research are to evaluate the relative sensitivity of northern aquatic invertebrates and northern ecosystems in comparison to southern species and environments. The focus of comparisons is in relation to the toxicity of rare earth elements. Approximately 3 to 5 sites will be chosen for detailed samplings and examples could include (Pontoon Lake, Trappers Lake and Tibbitt L...


Assessment of the condition of freshwater streams in the South Nahanni watershed
Principal Investigator: Steedman, Audrey
Licenced Year(s): 2016
Summary: The main objectives of this research project are to determine if macroinvertebrate community structure and composition is changing over time in freshwater streams in the South Nahanni watershed; and, to determine whether mining activities degrade the health of streams in the South Nahanni Watershed and define zones of degradation due to mining activities. These test sites are downstream of mines. ...


Examination of distribution and density of juvenile Dolly Varden char in Fish Creek (Rat River)
Principal Investigator: Maier, Kris
Licenced Year(s): 2016 2015 2014
Summary: The research teram seek to build on the 2014 & 2015 success in monitoring habitats and using electrofishing to assess juvenile Dolly Varden occupancy. Specific objectives include: 1) continue implementing a community-based monitoring program to monitor essential habitats; 2) further delineate the spatial distribution of juvenile char in the Fish Creek watershed; and, 3) finalize the occupancy mode...


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...
