Cumulative impacts of metal deposition in the NWT: Using lead isotopes to trace local, regional and long-range sources
Principal Investigator: Chételat, John
Licenced Year(s): 2014 2013
Summary: Yellowknife Bay on Great Slave Lake is a water body of cultural, subsistence and recreational importance for the Yellowknives Dene First Nation (YKDFN) and residents of Yellowknife. The ecosystem health of Yellowknife Bay has been impacted by historical mining releases of metals (particularly arsenic), as well as long-range atmospheric transport of metals such as mercury from far-away human emissi...


Sediment core studies in Great Slave Lake
Principal Investigator: Evans, Marlene S
Licenced Year(s): 2014
Summary: The objectives of this research project are to collect a series of sediment cores in the West Basin of Great Slave Lake to investigate time trends in various chemicals of interest including mercury, mercury isotopes and persistent organic contaminants. In late-March 2014, the research team will collect sediment cores at 3-4 locations on Great Slave Lake (West Basin, offshore Slave River). An 8...


Waste rock studies at a diamond mine site
Principal Investigator: Blowes, David W.
Licenced Year(s): 2014 2013 2012 2011 2010 2009 2008 2005
Summary: This research study is designed to investigate the processes related to water quality and quantity (collected at different scales) draining from country rock stockpiles that are located in areas of continuous permafrost. The quality of water draining from a country rock stockpile is determined by the combined effects of oxygen transport in the air phase, biogeochemical processes that control miner...


Marian Watershed Community-Based Aquatic Effects Monitoring Program
Principal Investigator: Garner, Kerri
Licenced Year(s): 2013
Summary: The Tlicho Lands Moratorium was lifted in June 2013, and development pressure is expected to increase on Tlicho Lands. As Tlicho Lands are in relatively pristine condition, the intent of this study is to begin to collect baseline data at sites prioritized by community members away from specific project footprints in order to analyze the cumulative impacts of development, climate change, and increa...


The prospects for collaborative approaches to transboundary water governance: the Mackenzie River Basin, Canada
Principal Investigator: Morris, Michelle J
Licenced Year(s): 2013
Summary: The primary objective of this research is to determine the extent to which collaboration can contribute to socially and environmentally sustainable transboundary water governance where power asymmetries exist. A secondary objective is to identify strategies and tactics that can be used by less powerful actors to achieve their goals in water management agreements. Data will be collected via sem...


Variability in peat plateau energy balance and water chemistry along a warming gradient
Principal Investigator: English, Michael C
Licenced Year(s): 2013
Summary: This research is physically based on a peat plateau and a peat bog, both close to Yellowknife. There are two primary objectives to this research. The first involves quantifying surface energy balances in areas where degradation of peat is pronounced and where it is not. Suprapermafrost water from the degraded and non-degraded sites will be analyzed for nutrients and dissolved organic carbon (DOC) ...


Phase III ESA & RAP for Stark Lake Exploration Site, NT
Principal Investigator: Barnes, Keith G
Licenced Year(s): 2013
Summary: The objectives of this year’s work program are to: 1. Complete a Phase III Environmental Site Assessment of the site, to further assess and delineate areas of concern on the site to support Remedial Action Plan development; 2. Complete a hazard assessment of the Stark Lake Site to support the development of a health and safety plan, and ensure that the Crown’s due diligence in regards to ...


Great Slave Lake Area Mines: 2013 Sampling Program
Principal Investigator: Wiatzka, Gerd M
Licenced Year(s): 2013 2012 2011 2010
Summary: The objective of the 2013 Great Slave Lake Mines Sampling Program is to assist Aboriginal And Northern Development Canada-Contaminants And Remediation Directorate (AANDC-CARD) with its ongoing work to clean up abandoned mine sites across the Northwest Territories. The program aims to collect additional environmental data which will be used to confirm current site conditions and to assist with fina...


Food Security and Drinking Water Vulnerability Assessment Related to Permafrost Degradation in the Jean Marie River First Nation
Principal Investigator: Ireland, Margaret
Licenced Year(s): 2013
Summary: The main objective of this one year project is to provide the community with a practical tool for assessing Jean Marie River’s (JMR’s) vulnerability to food security in relation to country foods, as well as the vulnerability of sources of country foods and drinkable water used by the community members out on the land, in the context of climate change. This tool will consist of a mapping of permafr...


PWGSC Gordon Lake Environmental Site Assessments
Principal Investigator: Nyman, Jeff
Licenced Year(s): 2013
Summary: The objective of this program is to determine the environmental and physical conditions at nine sites on Gordon Lake. 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 (including vegetation, fish, benthic invertebrates) m...
