Giant Mine Phase 4 Environmental Effects Monitoring
Principal Investigator: Harris, Katherine M.
Licenced Year(s): 2012 2010
Summary: The objective of this study is to examine the health of two small-bodied fish species (Slimy Sculpin and Ninespine Stickleback) exposed to treated effluent from Giant Mine. Data collected during this study will be assessed to determine if there are treated effluent related effects. The study will be conducted within the exposure areas (Baker Creek and Yellowknife Bay) and the reference areas (Yell...


Aquatic Environmental Effects Monitoring - Flat River at Cantung Mine
Principal Investigator: Hoos, Rick
Licenced Year(s): 2012 2009 2002
Summary: The objectives of this research are: (1) to determine length, weight, and general condition of 100 fish and tissue analysis of not more than 10 fish (Slimy Sculpin- Cottus cognatus) per site at five site locations in the Flat River: two locations upstream of the CanTung mine site, one adjacent to the mine site and at two locations downstream of the mine site; and, (2) to determine sediment and w...


Biophysical Baseline Studies in Support of the Izok Project
Principal Investigator: Trusler, Scott
Licenced Year(s): 2012 2008
Summary: The objectives of the research studies are the following: refine understanding of baseline conditions; provide input to design mitigation; evaluate potential changes in the environment in relation to the Izok Project; and contribute to the ongoing data collection of the Arctic environment. The Minerals and Metals Group (MMG) Canada team of environmental consultants will collect and review exist...


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...


Con Mine Environmental Effects Monitoring (EEM) Cycle 2
Principal Investigator: Machtans, Hilary
Licenced Year(s): 2015 2012 2009 2007
Summary: The main objective of the present study is to characterize site conditions to fulfill specific requirements of federal regulations. These studies will include fish, fish habitat, benthic macroinvertebrates, sediment and water quality sampling. Study areas will include locations both exposed and unexposed to mine effluent. The purpose of these surveys is to characterize environmental conditions ...


Shell Canada Limited Summer 2006 Historic Well Site Investigations
Principal Investigator: Warren, Randall
Licenced Year(s): 2006
Summary: The purpose of the proposed study is to examine twenty-two historic well sites within the Inuvialuit Settlement Region, eight of which are located within the Kendall Island Bird Sanctuary. Investigations on six of the twenty-two sites will comprise geophysical surveys, and collection of benthic invertebrates, soil sediment, surface water samples, soil invertebrates and arthropods and plant tissue....


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...


Sediment Transport Processes In A Sub-Arctic Stream
Principal Investigator: Rempel, Laura L
Licenced Year(s): 2006 2005
Summary: This project will characterize sediment transport processes, including bed scour and fine sediment deposition, in a sub-arctic stream intersected by the proposed Mackenzie Gas Pipeline. The study will meet five objectives: to characterize bed sediment texture; determine bed and suspended sediment transport rates during spring flooding; measure depth of bed scour during spring flooding; measure ne...


2005 Summer and Fall Aquatic Studies in the Inuvialuit Settlement Region
Principal Investigator: Povey, Andrew
Licenced Year(s): 2005 2004 2003 2002
Summary: From 2001 to 2004, aquatics studies were done in the Niglintgak, Taglu and Parsons Lake lease areas and along the proposed gathering pipeline. In addition, aquatic studies at proposed infrastructure sites and borrow pits were initiated in 2004. The 2005 studies are a continuation of the work done in previous years. The work will include additional investigations into fish and fish habitat, hydrolo...


2005 Summer and Fall Aquatic Surveys in the Gwich’in Settlement Area
Principal Investigator: Povey, Andrew
Licenced Year(s): 2005 2004 2003 2002
Summary: As part of the Mackenzie Valley Gas Project, baseline aquatic studies in the Gwich’in Settlement Area (GSA) will continue in 2005. The work will include additional investigations into fish, hydrology and water quality in rivers and lakes previously visited, as well as summer and fall aquatics studies of waterbodies near the infrastructure sites, access roads, and borrow pits. All of the aquati...
