Recent changes in carbon source-sink relationships and greenhouse gas emissions in forest and peatland ecosystems along the Mackenzie Valley region of Canada
chercheur principal: Bhatti, Jagtar
Année(s) de permis: 2011 2010 2009 2008 2007
Résumé: 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...

Tammerlane Baseline Studies
chercheur principal: Hoos, Rick
Année(s) de permis: 2006
Résumé: The objective is to obtain sufficient baseline data to develop a lead and zinc mine adjacent to the old Pine Point property. The owl survey to identify species presence and breeding territories in the vicinity of the study area will include an evening broadcast-call program that will commence 0.5 hours after sundown to 0.5 hours before sunrise in April and May. This owl survey will target the Bor...

Post-fire forest regeneration in the Western Canadian continental boreal forest: measurement and landscape modeling
chercheur principal: Gal, Ruth A.C.
Année(s) de permis: 2005
Résumé: The objective of this study is to develop a landscape model capable of predicting regeneration after fire in the Northern Boreal Forest. Data has been collected in the past from Porter Lake (near Lutsel K'e), Big Fish Lake, Alberta, and Wood Buffalo National Park, between Pine Lake and Peace Point. Data has also been collected from the International Crown Fire Modeling Experiment near Fort Pro...

New ischnacanthid acanthodians from the Lower Devonian of the Mackenzie Mountains, NT, Canada
chercheur principal: Hermus, Chelsea
Année(s) de permis: 2002
Résumé: The main objective of the project is to collect fossils of two specific groups of early fishes (acanthodians and heterostracans) to supplement specimens already collected for research projects at the University of Alberta. The field party plans to journe...

Collection of Silurian fishes and trilobites and articulated remains of Devonian chondrichthyans and other fishes from the Mackenzie Mountains, N.W.T.
chercheur principal: Wilson, Mark V.H.
Année(s) de permis: 2013 1998 1996 1990
Résumé: The objectives of the research are 1) to collect remains of Silurian and Devonian fishes, and 2) to collect remains of Silurian trilobites. Activities are limited to travel, residence at camp locations and collection of fossils. Helicopters will be used to access camp sites. We plan to land at Avalanche Lake on July 15, spending 6 days collecting fossils at Avalanche Lake, followed by one day of t...

Implications of climatic change on water-based recreational activities in Nahanni and Jasper National Parks
chercheur principal: Staple, Tamara
Année(s) de permis: 1993
Résumé: The research in Nahanni National Park includes the setting up of programs to monitor water depth and vegetational changes along the river. Changes in water depth influence the ability of navigating the river, especially in areas of rapids, and has implications on the level of expertise required by visitors travelling the river. Monitoring vegetation along the river will provide information about...

Paleobiology of Reef Faunas in Middle-Upper Devonian Strata in the Hay River Area
chercheur principal: Johnston, Paul A.
Année(s) de permis: 1992
Résumé: The researcher and his team will look for fossils of reef animals. Notes will be taken on the growth positions of the reef animals, and about 400 kg of fossils will be collected by hand or with hammers and chisels from various localities. The fossils will be brought back to the Royal Tyrrell Museum and used to make molds. Casts from these molds will be used to make an exhibit showing a three-di...

Digital Database of Vegetation Types of the Mackenzie Valley Development Corridor
chercheur principal: Squires Taylor, Cindy
Année(s) de permis: 1992 1991
Résumé: The Researcher will conduct a survey, approximately 30 km on either side of the Mackenzie River using satellite imagery. A classification will be undertaken of the area from the Mackenzie Delta to the Fort Simpson area, with wider zones along the east side to include proposed pipeline routes. The information can be plotted as colour maps to show the location of trap lines, forest fires or wildlife...
