Ekati Engineering and Environmental Monitoring Programs
Principal Investigator: Pacholski, Laura J
Licenced Year(s): 2018 2017 2016 2015 2014 2013
Summary: The main objectives of the field work for 2018 will be to determine if the Ekati Diamond Mine is having an effect on the surrounding aquatic environment and air quality, and 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 2.5L Niskin (a cylindrical PVC water sampler). During the week of spring fresh...


De Beers - Gahcho Kué Environmental Monitoring Program
Principal Investigator: Kramers, Patrick
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010
Summary: The objective of the proposed studies is to obtain information on the environment once Project activities commence to determine potential project effects. The proposed studies will include the collection of air quality, geochemistry, hydrology, water and sediment quality, and fish and aquatic resources, dustfall, vegetation and soil information. The studies (further defined below) are designed...


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): 2018 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...


The Arctic Great Rivers Observatory III
Principal Investigator: Holmes, Robert Max
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The Arctic Great Rivers Observatory project studies the six largest rivers in the Arctic: the Mackenzie and Yukon Rivers in North America, and the Ob', Yenisey, Lena, and Kolyma Rivers in Russia. We are interested in how climate change is impacting Arctic rivers. The research team will take measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) and try to det...


Remote sensing of Arctic-Boreal surface water
Principal Investigator: Smith, Laurence C.
Licenced Year(s): 2017
Summary: The goal of this project is to measure variations in water surface elevation, inundation extent, permafrost presence/absence, active layer thickness, soil moisture and related variables for lakes, wetlands and rivers in four primary study areas within the Northwest Territories (NWT). Using ground measurements combined with maps of water surface elevation produced by the Air Surface Water and Ocean...


The effects of wildfire on diverse aquatic ecosystems of the NWT
Principal Investigator: Tank, Suzanne E
Licenced Year(s): 2017 2016
Summary: The objective of this study is to determine the effect of fire on water quality within the southern NWT landscape. The research team will work across the Taiga Plains and Taiga Shield ecoregions. Differences in landscape between these regions will affect the catchment response to fire. The team will also target catchments with variable permafrost extent, and wetland/lake coverage. The research ...


NTPC Bluefish Hydro Repairs
Principal Investigator: Panayi, Damian
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010
Summary: The objective is to describe the aquatic environment in the Yellowknife River between Bluefish Lake and Prosperous Lake as per the Fisheries Authorization and the Water Licence. This may include investigating aquatic vegetation, water quality and quantity, benthic invertebrates, fish and substrate. The results will be used to determine the most suitable means of fish habitat compensation or produc...


Kennady North Diamond Project
Principal Investigator: Panayi, Damian
Licenced Year(s): 2017 2016
Summary: The objective of this research is to document existing environmental conditions surrounding the Kennady North Diamond Project. Hydrology studies include the measurement of selected lake inflow and outflow and stream profile through field surveys, and installation of data loggers to continually monitor lake levels through the open-water season. Hydrology studies will be initiated during the spri...


Biogeochemistry of Lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licenced Year(s): 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: The objective of this research project are to: 1) improve the understanding of microbial carbon-processing in Mackenzie Delta lakes and how it is affected by the changing water levels; and, 2) to decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine nutrient flow to the ocean. This work will help resolve what drives microbial communities in Mackenzi...


A Program to Evaluate Changing Northern Lake Ice Regimes
Principal Investigator: Prowse, Terry D
Licenced Year(s): 2017 2016
Summary: The objective of this research project is to complete on ice snow depth, ice thickness and composition survey along with collection under ice core water quality and biological information. Sample locations from previous years are located using a handheld GPS. On ice snow depth is measured using a tape measure. An ice auger is used to penetrate the ice cover and evaluate if white ice is present...
