Diavik Aquatics Effects Monitoring Program
Principal Investigator: Wells, David A
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2005 2004 2003 2002 2001
Summary: The objective of this project is to revisit fixed sample stations at near-field, mid-field and far-field sites over the course of the year in an effort to determine any seasonal variation that may exist and confirm impact predictions. The AEMP Version 3.5 will consist of the following components: Traditional Ecological Knowledge, Dust Deposition; Effluent and Water Chemistry; Indicators of Eut...


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...


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...


The influence of forest fires on metal deposition to lakes and peatlands in the North Slave Region, NWT
Principal Investigator: Chetelat, John
Licenced Year(s): 2016
Summary: The research team will use natural environmental archives (lake sediment and peat cores) to characterize the forest fire history in the study region and test the relationship between fire events and metal accumulation over recent centuries. Study sites will be selected along a gradient of recent forest fire activity with some study sites located in areas of the latest burns (2014-15) to examine th...


Holocene Glacier Fluctuations in Nahanni National Park Reserve, Northwest Territories, Canada
Principal Investigator: Menounos, Brian p
Licenced Year(s): 2016
Summary: The objective of the study is to date the formation of terminal moraines fronting Brintnell Glacier, and analyze the glacigenic signature within the sediments of Glacier Lake in order to develop a robust chronology of glacier change on the Brintnell-Bologna Icefield. This decade to century scale chronology will be compared to regional-to-hemispheric climate proxies to evaluate the climate sensitiv...


Hydrological and contaminant studies in the Marian Watershed, NWT, to enhance community-based cumulative effects monitoring
Principal Investigator: Wolfe, Brent BBW
Licenced Year(s): 2016
Summary: While water and sediment quality monitoring in areas of industrial developments is an integral part of water management programs to ensure protection of ecosystems, absence of long-term measurements can make it challenging to define reference conditions effectively. As a contribution to the Marian Watershed Stewardship Program (MWSP), this research uses paleolimnological approaches to establish ba...


Studies of methane release from lakes in the Mackenzie Delta and on Richards Island
Principal Investigator: Orcutt, Beth N
Licenced Year(s): 2016 2015
Summary: The focus of this project is to study methane release from different lakes in the Mackenzie Delta and Richards Island area, with a focus on capturing a full ice in/ice out cycle, to determine how much methane is released from lakes under different conditions and how microorganisms increase or decrease methane release. As part of this project, eight experiments the size of a milk crate were dep...


De Beers - Gahcho Kué 2014 Environmental Monitoring Program
Principal Investigator: Chisholm, Veronica
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010
Summary: The objective of the proposed studies is to continue to describe the existing environment, and obtain information 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 are...


EKATI Engineering and Environmental Monitoring Programs
Principal Investigator: Lee, Claudine
Licenced Year(s): 2016 2015 2014 2013
Summary: The main objectives of the field work for 2016 to 2020 are: 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 2.5L Niskin (a cylindrical PVC water sampler). During the week of ...


Characterization of arsenic species in lake sediments surrounding Giant Mine, NWT.
Principal Investigator: Van Den Berghe, Martin
Licenced Year(s): 2016 2015
Summary: The purpose of this study is to determine whether the arsenic present in regional lake sediments is of natural or anthropogenic origin, and whether these lakes act as a sink (capture) or a source (release) of arsenic in the overlying lake waters. By evaluating the relative stability of arsenic species in these different chemical media, the research team may establish the long term trends of arseni...
