Development and application of monitoring tools to quantify the effects of mining on the health of rivers in the South Nahanni Watershed (NWT)
Principal Investigator: Scrimgeour, Garry J
Licensed Year(s): 2009 2008 2007
Summary: The objectives of this research are two-fold: 1) Identify an ecological indicator that can monitor changes in loadings of metals in the South Nahanni Watershed. This work is scheduled for completion in 2007-2008. 2) Establish a monitoring program that can quantify the cumulative effects of mining activities on the health of streams in the South Nahanni Watershed. This work is scheduled for compl...


Close Encounters: Continued Investigations into 19th-20th Century Copper Inuit and European Intersocietal Interaction
Principal Investigator: Johnson, Donald S.
Licensed Year(s): 2007 2006 2005 2004 2003
Summary: Project a: essentially fifth year of research (sixth-year if associated work in 2000 is counted), and seeks to continue heretofore successful investigations into the nature, substance and long-term effects of contact between Copper Inuit and Europeans/Eurocanadians in the 19th and 20th centuries utilizing sociocultural, archaeological, and economic methodologies, b. Project seeks to initiate a col...


Biological studies of waters along the proposed Mackenzie Gas Pipeline route - Gwich'in Settlement Region
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2009 2008 2007 2006
Summary: While data collected during the Environmental Impact Assessment studies (carried out in conjunction with the proposed construction and operation of the Mackenzie Gas Pipeline) are relatively comprehensive in describing the major physical-chemical features of the aquatic environment, they are lacking in the descriptions of the biological features of these environments, and as a consequence, their s...


Biological studies of waters along the proposed Mackenzie Gas Pipeline route - Inuvialuit Settlement Region
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2009 2008 2007 2006
Summary: This study is designed to fill gaps in Environment Canada’s understanding of the aquatic environment potentially impacted by various aspects of the Mackenzie Gas Project (MGP). Potential stressors including: increased erosion, nutrient releases from sewage discharges, other chemical releases, water withdrawals, impacts of barge traffic, increased atmospheric emissions, etc. The focus will be on th...


Aquatic Studies in support of the Discovery Mine Remediation Work
Principal Investigator: Ford, Bruce S
Licensed Year(s): 2005
Summary: This study involves fish sampling to determine relative abundance and levels of mercury and other metals in fish tissue in Giauque Lake, Thistlethwaite Lake and Control Lake A, as well as benthic invertebrate sampling and water quality sampling in the three lakes to complement the fish sampling. 3 sites in Giauque, 3 in Thistlethwaite and one in Control Lake A will be recorded. Captured fish will ...


Aquatic Studies along the Mackenzie River and its Tributaries
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2005
Summary: This study is designed to investigate various measures of small fish health at a number of locations along the Mackenzie River. The researchers want to find out if small fish health is different near oil seepages and the islands at Norman Wells than in other parts of the river. Also, the researchers will investigate fish and benthic invertebrate abundance and species composition at selected strea...


Ecological Conditions in the Proposed Discharge Route of the Colomac Mine, NT
Principal Investigator: McGurk, Michael
Licensed Year(s): 2005 2004
Summary: The researchers will measure water quality, aquatic ecology and the status of fish populations in ponds and lakes along the proposed discharge route of mine water from the Colomac Mine (North Pond, L-Shaped Lake, Paddle Lake, Lake 315, and Lower Lake) and compare those data with data collected from reference lakes (Steeves Lake, Baton Lake, and Spanner Lake). Work will include taking three samples...


Effects of climate change on coastal geomorphology and benthic biotic communities, southwestern Banks Island
Principal Investigator: Edinger, Evan N
Licensed Year(s): 2005
Summary: Climate change is affecting coastlines and coastal communities across Arctic Canada. Communities in the Western Arctic, including Sachs Harbour, have described a variety of effects, including warmer temperatures, reduced sea ice thickness, longer duration of open water in summer, increased wave activity, and new or early arrivals of migratory animals. These effects can have a variety of impacts ...


Environmental Surveys for the Fortune Minerals NICO Project
Principal Investigator: Goad, Robin E
Licensed Year(s): 2017 2016 2014 2013 2012 2011 2010 2009 2008 2006 2005 2004 2003
Summary: Fortune Minerals is considering an expanded exploration program on the NICO property, which will include building an all-weather access road. This program will require environmental baseline surveys to augment existing information on species and habitat...


2004 Baseline Aquatic and Fisheries Survey of Fox Pit Area
Principal Investigator: Granchinho, Sophia
Licensed Year(s): 2004
Summary: BHP Billiton has retained Rescan Environmental Services Ltd. to conduct a baseline aquatic and fisheries survey of lakes near the Fox Pit in the Koala Watershed on the EKATI claim block. The Fox Pit is the newest pit being constructed at EKATI. The wast...
