Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2008
Summary: The research will examine streams possibly affected by the proposed Mackenzie Gas Project pipeline, and streams that can serve as future control/reference sites. Measurements of stream nutrients, metals in stream water, water quality (DO, pH, conductivity, etc.), stream characteristics (flow, width, depth, etc.) and aquatic invertebrate abundance/species composition will be completed. Possible t...

Principal Investigator: Essar, Natasha
Licensed Year(s): 2008
Summary: The objective of this study is to determine fish presence, distribution and abundance in water bodies in the Project area. The age/size frequency distribution, wintering habitat and spawning habitat will be examined, and the metal burdens determined, along with fish presence and distribution along road and bridge crossings. The study will use a combination of methods including minnow traps, fyk...

Principal Investigator: Elliott, Milissa A
Licensed Year(s): 2008
Summary: This project seeks to identify and measure specific characteristics of plants to determine the current baseline conditions of the vegetation, collect grass samples to test for different species of fungi and integrate traditional knowledge of environmental systems with current biological sampling. Transects (a long straight line) will be measured out from the edge of a road to about 1 km away fr...

Principal Investigator: Nielsen, Jennifer L.
Licensed Year(s): 2008 2007
Summary: This study aims to: 1) use genetics and otolith (ear bone) microchemistry to determine if differences exist between collections of Arctic cisco (herring) made from tributaries of the Mackenzie River (Canada) and the Colville River (Alaska) and 2) use differences to identify population-of-origin of fish caught in the Colville River subsistence fishery. Approximately 60 Arctic cisco will be colle...

Summary: The objective of this research is to assess variations and processes controlling CO2, CH4 and N2O dynamics along the Mackenzie Valley, to investigate the amount and character of greenhouse gases released, and to understand conditions controlling soil GHG emissions. Soil gas sample tubes will be sampled on a seasonal basis for gas concentration (CH4, N2O, CO2) and isotope ratios. The response of...

Principal Investigator: Hoos, Rick
Licensed Year(s): 2007 2006
Summary: Objectives of the aquatics studies are to determine fish presence/absence, characterize habitat and add to data collected in a similar programme in 2006. The objective of the water-quality sampling is to continue collection of data in streams and tributaries which flow through the project area. Hydrometric monitoring will enhance the flow history of streams down-gradient of the site. The objective...

Principal Investigator: Howland, Kimberly
Licensed Year(s): 2007 2006 2005
Summary: The objectives of this study are to: 1) gather baseline data on size and age structure, fecundity (egg number per female), growth and mortality of Dease, Smith, McVicar, McTavish, Keith arm lake trout. A different arm will be sampled each year over a 5 year time period. 2) To determine if lake trout are genetically distinct between basins. 3) To determine the extent of movements (if any) by lake t...

Principal Investigator: Hoar, Bryanne M
Licensed Year(s): 2009 2008 2007
Summary: The objective of the research is to determine the development and survival of Ostertagia gruehneri in the region of Daring Lake, and their patterns of egg laying in caribou. Faeces infected with O. gruehneri eggs will be plotted weekly. Ambient temperature and relative humidity will be measured hourly at ground level (HOBO data logger). Samples will be removed from the faecal plots biweekly t...

Principal Investigator: Tallman, Ross F
Licensed Year(s): 2006
Summary: This study involves the assessment of valued fishes in lakes along the proposed Mackenzie Pipeline route. There is little information on fish populations in any of the smaller inland lakes of the region. Through community consultation in Fort Good Hope it was determined that Yeltea Lake should be studied. Yeltea Lake is utilized by residents for sustenance (containing lake trout, broad whitefish, ...

Principal Investigator: Seccombe-Hett, Pippa
Licensed Year(s): 2006
Summary: The main activities in this program are: 1) forming a project steering committee involving industry, aboriginal groups and government; 2) identifying plant species suitable for revegetation; 3) developing practices for commercial production; and 4) identifying employment opportunities. Seed collection will be carried out in late August through to mid-September. Sites will be accessed by boat an...
