2017 Tarsuit Caissons Removal Program
Principal Investigator: Clarke, Kim P
Licenced Year(s): 2017
Summary: The objective of this project is to refloat and remove the Tarsuit Caissons from Lease Area 117/D11-3-7. Following their removal, the research team will conduct the following evaluation of the affected site and adjacent area: 1) Side Scan Survey 2) Macro invertebrate Survey A sidescan/multibeam unit (Edgetech 6205, or similar) will be pole mounted on the bathymetry vessel and data will be col...


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...


EKATI Engineering and Environmental Monitoring Programs
Principal Investigator: Lee, Claudine
Licenced Year(s): 2017 2016 2015 2014 2013
Summary: The main objectives of the field work for 2014 to 2018 will be (1) to determine if the Ekati Diamond Mine is having an effect on the surrounding aquatic environment and air quality; and (2) to provide baseline data for areas where mine development may occur in the future. In winter, water samples will be collected under ice using a 5L Niskin (a cylindrical PVC water sampler). During the week o...


Characterization of the reference condition of northern biota and assessment of potential changes due to mining
Principal Investigator: Dube, Monique G
Licenced Year(s): 2006
Summary: The objectives of this research are three-fold: 1) to determine the natural variability of benthic invertebrate and fish communities at sites free of human impact; 2) to determine any changes in these due to mining activity relevant to regional variability; and 3) to establish dose response relationships and critical thresholds for stressors including mine effluent, ammonia, a hydrocarbon indicato...


Persistent organic contaminants in the Great Slave Lake ecosystem.
Principal Investigator: Evans, Marlene S
Licenced Year(s): 1995 1994
Summary: The researchers will collect samples of sediments from the bottom of Great Slave Lake at sites near Fort Resolution and Lutsel K'e. This data will allow a better understanding of how fast sediments are deposited on the lake bottom in various regions. Researchers will also collect invertebrates and fish samples as part of an overall study of contaminants in the lake's ecosystem....
