The effect of permafrost slumping on carbon delivery from land to water
Principal Investigator: Tank, Suzanne E
Licenced Year(s): 2016 2015 2014
Summary: The objective of this study is to understand how permafrost slumping increases the mobilization of organic and inorganic carbon from land to water, and the effects of this movement on stream communities. To do this work, the research team will measure streamwater chemistry upstream and downstream of slump sites. The team will also examine the fate of this carbon by undertaking incubation experimen...


The Continuation of a Community-led Fish Monitoring Study in Déline, NT 2012
Principal Investigator: Macdonald, Colin R
Licenced Year(s): 2012 2010 2009
Summary: To determine the levels of potential chemicals of concern in three major fish species through the analysis of muscle and liver samples for mercury, radionuclides and a number of elements. Fish of three species (lake trout, lake whitefish and lake herring) will be collected in the Keith Arm of Great Bear Lake near the community of Deline. Approximately 15 trout and 10 whitefish and 10 herring wi...


Dezé Energy Corporation Ltd. Taltson Expansion Project
Principal Investigator: Azzolini, Louie
Licenced Year(s): 2009 2008
Summary: This licence is being issued for the scientific research application No. 1124. This is a three part study with separate objectives for each. The objectives are as follows: 1) The Fish Study: Evaluate the impacts associated with four locations requiring in-stream works; quantify and qualify fish habitat values at each of the four locations; identify potential locations to improve existing fish...


Acoustic and Biological Test Study for the WesternGeco 2D Mackenzie River and Delta Seismic Programs
Principal Investigator: Rosindell, Keith
Licenced Year(s): 2002
Summary: A test program has been designed in response to National Energy Board, Department of Fisheries and Oceans, and Resources, Wildlife and Economic Development requests to collect information on seismic airgun acoustics within the Mackenzie River and on asso...


Gahcho Kue (Kennady Lake) Baseline Environmental Studies - Fisheries Program 2001
Principal Investigator: Couture, Richard
Licenced Year(s): 2007 2004 2001 2000
Summary: If future feasibility studies determine that a mine should be developed for access to the diamondiferous kimberlite underlying Gahcho KuÚ, the lake will be dyked and partially drained as has been the case at other diamond properties in the NWT. As such, the Fisheries Act requires compensation for lost fish productivity and lost habitat. To determine the amount of compensation DeBeers Canada...


Phase 2 Environmental Baseline Program: Aber/Kennecot Southwest Diavik Property, Lac de Gras, NWT
Principal Investigator: Bryant, Wayne
Licenced Year(s): 1996 1995
Summary: The researchers will be involved in a mult-disciplined, integrated and focused series of investigation regarding water quality, hydrology and climatology, fisheries, aquatic, wildlife, vegetation, soils and terrain, and heritage resources. Taken with complementary socio-economic, traditional knowledge and environmental management investigations, this data will be used to prepare an environmental ...


Enviornmental assessment/monitoring studies of the aquatic resources in the Lac De Gras area.
Principal Investigator: Reed, Shawna
Licenced Year(s): 1995
Summary: The researchers will be utilizing the following techniques for assessing aquatic biota and fish habitat utilization: gillnetting (various sizes and meshes), trapnetting (mark-recapture program), minnow-trapping and electroshocking (backpack model). A select number of fish will also be retained for aging (using otoliths), tissue metals concentration and diet analysis....


Environmental Studies of the Aquatic Resources of Spyder Lake.
Principal Investigator: Reed, Shawna
Licenced Year(s): 1994
Summary: The researcher will determine fish presence/absence and/or densities (number of fish per unit stream length) by electrofishing representative habitat (eg. pool, riffle, run) and the setting of baited minnow traps. When these two methods are not practical (eg. depth too great or flow too fast), gillnets and/or beach seines will be used. Fish caught will be identified, measured, weighed, sexed and t...


Ecology and population genetics of freshwater invertebrates of the Arctic.
Principal Investigator: Boileau, Marc G.
Licenced Year(s): 1988 1987 1986
Summary: To investigate the ecology and population genetics of crustacean zooplankton; to study the genetic diversity of the major species of copepods and their dispersal since deglaciation; to clarify the taxonomy and improve distribution records....


Suphur bacteria and chemical analysis of two meromictic lakes
Principal Investigator: Dickman, Mike
Licenced Year(s): 1988
Summary: To investigate photosynthetic sulphur bacteria present in two meromictic lakes; to determine chemical and biological characteristics of two meromictic lakes (water does not turn over and bottom layer is without oxygen)...
