Principal Investigator: Evans, Kevin
Licensed Year(s): 2002
Summary: Research program on the fish, plankton and benthic communities. Potential effects of the drilling program on benthos include effects of chemical contaminants from drilling fluid wastes on the benthic community and hence the food web, and loss/change in b...

Principal Investigator: Lawson, Nick
Licensed Year(s): 2001
Summary: The objectives of the research team are to collect baseline environmental information on the DeBeers Canada Exploration Ltd. project at Kennady Lake, to assist with the current environmental management of the property and prepare for an assessment of the environmental effects of potential future development of the site. Three field visits to Kennady Lake will be completed during the summer of 200...

Principal Investigator: Grabke, Dan
Licensed Year(s): 2000
Summary: In 1999, the Northwest Territories Power Corporation was awarded a 25 year water licence to operate its three hydroelectric plants on the Snare River. Conditions of this water licence included that two studies be done by the Corporation. The first study is an assessment addressing the removal of minimum flow requirements on two of the dams. This study will include a current assessment of fish a...

Principal Investigator: Madsen, Eric
Licensed Year(s): 2001 2000
Summary: This research will monitor and evaluate the potential environmental effects from the construction and operation of a diamond mine. The activities planned for 2000 include: water sampling in Lac de Gras and east island streams and lakes, fish-out study on inland lakes, radio-tagging of lake trout in Lac de Gras, tissue sampling of Slimy Sculpin in Lac de Gras, benthic invertebrate sampling and lake...

Summary: Recently BHP Diamonds Canada has "dewatered" a number of lakes and created a diversion channel to re-route water around two open pit mines. The purpose of this study is to compare the effectiveness of the diversion canal as habitat before and after it is enhanced with fish habitat structures and also in relation to natural streams in the area. In early spring Arctic grayling will be captured in we...

Principal Investigator: Siferd, Tim
Licensed Year(s): 2000 1999
Summary: The objective of this study is to determine population size or growth rate and recruiment levels for clams and other benthic resources in Sachs Harbour, Blue Fox Harbour, and Sea Otter Harbour. Sampling for the project will be conducted from the vessel Tucho Mariner and an additional Coast Guard launch. Equipment/sampling devices for the project include an underwater camera system, QTC view sea...

Principal Investigator: Hebben, Thorsten
Licensed Year(s): 1999
Summary: The objective of this study is to examine the migratory habits of epipelic algae in 10 small, shallow bodies of water in the region of the arctic circle. A 3/4 ton 4x4 pickup truck will be used to travel to each of ten ponds located 6 km north of Inuvik, N.W.T. The ponds will be sampled over a period of 2 days each between July 6 and July 20, 1999, using a technique perfected during the summer o...

Principal Investigator: Reed, Shawna
Licensed 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...

Principal Investigator: Pelletier, Clem
Licensed Year(s): 1994
Summary: In project area streams, fish presence/absence and/or densities will be obtained by electrofishing representative habitat. Benthic invertebrates ans periphyton (stream algae) will be sampled at stream sites to determine seasonal changes in composition, distribution and abundance. Lake fisheries population studies will involve fish trapping. Lake limnology, plankton and benthic invertebrates wil...

Principal Investigator: Couture, Richard
Licensed Year(s): 1994 1994 1993
Summary: Rescan Environmental Services Ltd. will continue their study on the types of fish and other aquatic organisms found in the Thonokeid Lake area. Data on species type as well as their age, abundance and habitat will be collected. In addition, muscle and liver tissue of fish will be collected in order to assess for the presence of heavy metal contaminants. This study will be summarized in an envir...
