Principal Investigator:McGeer, Jim Licenced Year(s):
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...
Principal Investigator:Steedman, Audrey Licenced Year(s):
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.

The research team seek to build on the 2014 success in monitoring habitats and using electrofishing to assess juvenile Dolly Varden occupancy. Specific objectives include: 1) to continue implementing a community-based monitoring program to monitor essential habitats; 2) to further delineate the spatial distribution of juvenile char in the Fish Creek watershed; and, 3) to establish a length at age ...

The objective of this program is to determine the environmental and physical conditions at nine sites on Gordon Lake and potentially six Gordon Lake south sites. This will include the identification and quantification of environmental impacts in soil, sediment, surface water and groundwater, and the identification of any hazardous or non-hazardous materials. In addition, samples of biota (includin...

The objectives of this research project are to: 1) determine why fish mercury levels vary among lakes in the Deh Cho region; 2) identify best predictors of fish mercury levels; and, 3) determine which fish have the lowest levels of mercury and highest levels of micro-nutrients and fatty acids.
The methods for this project include two parts, first is the collection of food web data from each lak...

To determine how spring and summer temperatures affect the abundance of the amphipod Gammarus lacustris throughout the summer. Over the 2 years of the experiment, the research team plans to use amphipods from 4 different sources over several latitudes (Montana-USA, St. Denis-SK, Yellowknife-NT, Inuvik, NT). Using this variety of geographic sources will allow us to assess if different populations...

This licence is issued for the scientific research application #861.
This study is designed to examine streams possibly affected by the proposed Mackenzie Gas Project pipeline and streams that can serve as future control/reference sites. The researcher will measure the following: nutrients and metals in stream water, stream water quality (DO, pH, conductivity, etc.), and aquatic invertebrate ab...

This licence is issued for the scientific research application # 835.
This research will examine lakes possibly affected by the proposed Mackenzie Gas Project pipeline, and lakes that can serve as future control/reference sites. Measurements of nutrients and metals in lake water and sediments, lake water quality (DO, pH, conductivity, etc.), and benthic invertebrate and plankton abundance/spec...
Principal Investigator:Schryer, Richard Licenced Year(s):
Under the new Metal Mining Effluent Regulations (Fisheries Act), an Environmental Effects Monitoring (EEM) program is required to determine the effects of mine effluent on fish and fish habitat. As part of the study, water quality and aquatic organism he...
