A multidisciplinary investigation of recovery in Yellowknife area lakes from 50 years of arsenic pollution: What are the factors inhibiting recovery and the biological consequences?
Principal Investigator: Palmer, Mike
Licenced Year(s): 2017
Summary: The overarching objectives of this research are two-fold: 1) to investigate watershed and within-lake abiotic processes affecting the recovery of mine-impacted lakes in the Yellowknife area, including storage and release of arsenic from soils, seasonal dynamics of arsenic export in runoff, and fluxes of arsenic to and from lake sediments; and 2)to investigate the toxicological consequences of ...


Further Examination of the Bio- Magnification of Mercury within Fish Species of the Dehcho and Their Varying Levels Among Lakes
Principal Investigator: Swanson, Heidi
Licenced Year(s): 2017 2016 2016 2015 2014 2013
Summary: The objectives of this research project are: 1) to determine why fish mercury levels vary among lakes in the Dehcho region; 2) to identify best predictors of fish mercury levels; and, 3) to 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 eac...


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...


Gordon Lake Assessment Project
Principal Investigator: Doucet, Michael
Licenced Year(s): 2016 2015
Summary: 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...
