The effect of permafrost slumping on carbon delivery from land to water
Principal Investigator: Tank, Suzanne E
Licenced Year(s): 2017 2016 2015 2014
Summary: The objective of this study is to understand how permafrost slumping increases the mobilization of organic and inorganic carbon from land to water, and the effects of this movement on stream communities. To do this work, the research team will measure streamwater chemistry upstream and downstream of slump sites. The team will also examine the fate of this carbon by undertaking incubation experimen...

Using the past to inform the future: A paleoecological perspective of the impacts of drought and fire on lakes, permafrost and forests
Principal Investigator: Pisaric, Michael FJ
Licenced Year(s): 2017 2016
Summary: The objectives of this research are to examine the frequency and severity of past wildfire and drought (drought-like) conditions in the southern Northwest Territories. Specifically, the research team will examine the following questions: 1) how frequent and severe have fires been in the past; 2) are fires becoming more frequent/severe due to the impacts of climate change; 3) what impact does wildf...

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): 2017 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...
