Quaternary stratigraphy in the Redstone River area
Principal Investigator: Normandeau, Philippe X.
Licenced Year(s): 2017
Summary: The research team will investigate sections of exposed sediments along the Redstone River banks and some minor tributaries to establish the provenance and composition of these sediments. The team will evaluate the possible presence of ancient preglacial sediments buried beneath glacial sediments. It is also believed that ancient lake sediment may be present outside of the present flood plains of t...


Beaufort Sea Coastal and Nearshore Geoscience Research 2017
Principal Investigator: Whalen, Dustin JR
Licenced Year(s): 2017
Summary: The objective of this project is to provide the means to improve the knowledge of physical conditions in the Arctic coastal zone in order to help government agencies, corporations and local residents understand mitigate and reduce the impacts of climate driven changes. Field surveys will be undertaken in consultation with Hunters and Trappers Committees (HTCs) in order to ensure the timing of ...


Developing New Tools for Assessing Legacy Pollutants and their Ecological Consequences in Lakes Near Northwest Territories Mines
Principal Investigator: Blais, Jules M
Licenced Year(s): 2017 2016 2015
Summary: The research team propose to develop tools to assess risks associated with legacy industrial developments in a northern setting. The team will investigate contaminants from the Giant Mine near Yellowknife Northwest Territories (NT), which operated between 1948 and 2004, producing a legacy of contaminants including arsenic, antimony, hydrocarbons, mercury, and others. This remediation strategy appl...


Terrestrial geoscience studies of earthquake (seismic) hazard in the Mackenzie-Beaufort area
Principal Investigator: Dallimore, Scott R
Licenced Year(s): 2015 2014
Summary: Industry and regulators require information on seismicity and its effect on engineering structures both at a regional and local scale. The primary source of this information is the National Building Code of Canada’s Seismic Hazard Value map. Ongoing work undertaken as part of the 2015 revision of this map suggests that an increased seismic (earthquake) hazard exists in the Mackenzie-Beaufort area....


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...


Impacts of recent climate warming on Canada’s northern aquatic ecosystems
Principal Investigator: Blais, Jules M
Licenced Year(s): 2014
Summary: The objectives of this research project are: 1) to determine the impact of shoreline expansion and forest/peat submergence from thawing permafrost on contaminant and carbon fluxes to lakes in the Yellowknife region; 2) to develop novel approaches to track terrestrial organic matter sources in lakes, in order to assess how climate warming and permafrost thaw are affecting the delivery of terrestr...


An investigation of arsenic speciation and toxicity in Baker Creek sediments from Giant Mine in the Northwest Territories, Canada
Principal Investigator: Nash, Tyler J
Licenced Year(s): 2012
Summary: The objective of this research project is to assess the sediment quality of Baker Creek. This will be achieved by analyzing factors influencing arsenic mobility from sediments to overlying water and assessing the toxicology of the sediments using exposure tests on indicator organisms. Core samples of Baker Creek sediments will be taken by the researchers using aluminum pipes driven into the gro...


2005 Aquatic Efects Monitoring Program
Principal Investigator: Wytrychowski, Scott I
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2005 2004 2003 2002 2001
Summary: The purpose of the 2005 Aquatic Effects Monitoring Program is to initiate a long-term aquatics sampling program in order to produce a data set that will be used in trend analyses to track the overall effects of the project on the aquatic ecosystem of Lac de Gras and to confirm predictions made during the Environmental Assessment. This is achieved by conducting consistent annual sampling at fixed m...


The Use of Sediment Data as an Indicator of Aquatic Ecosystem Health in the Coppermine River Basin, NWT
Principal Investigator: Peramaki, Liisa
Licenced Year(s): 2000
Summary: This study will investigate the quality of aquatic sediment and evaluate its potential as an indicator of ecosystem health in the Coppermine River basin. Sediment cores will be collected by boat or float plane at Lac de Gras and Point Lake. The following field measurements will be recorded: water temperature and pH, and sediment colour, texture and pH. In addition, personal interviews will be c...


The origin of deformed massive ice, Pleistocene Mackenzie Delta, Western Canadian Arctic
Principal Investigator: Murton, Julian B
Licenced Year(s): 1999 1998
Summary: The main objective of the proposed research is to establish the origin of massive bodies of underground ice at two key massive-ice localities in the Mackenzie Delta area: i) Cliff Point, Liverpool Bay and (ii) near Eskimo Lakes. The research will be carried out by an interdisciplinary team of scientists examining the geology, glaciology and chemistry of the ice and adjacent sediments. The research...
