Ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT.
chercheur principal: Kershaw, G. Peter
Année(s) de permis: 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Résumé: The main study objectives are to: 1) determine the status of permafrost landforms in the study area, and 2) determine long-term recovery after abandonment of the CANOL No. 1 project. Access during the summer is via the Yukon along the Canol Road through Macmillan Pass. Beyond the base camp mountain bikes and foot will be the means of transport. Automated microclimate stations powered by solar ene...


Geomorphologic analysis of the Mackenzie Delta, N.W.T. using spatial image processing.
chercheur principal: Boyes, Donald M.
Année(s) de permis: 1995 1994 1990
Résumé: The collection of the field data is required to calibrate satellite image clasifications and interpretations concerning water body measurements, plant community types, and sedimentation patterns. Field measurements will include measuring ground distances and recording plant characteristics. Nothing in the field area will be destroyed or removed....


Grizzly and Black Bear Habitat Use Study and Bear Hazard Assessment of the Rabbitkettle Lake Area of Nahanni National Park Reserve.
chercheur principal: Ashton, Sandra
Année(s) de permis: 1995 1994
Résumé: Data collection for food habits analysis will involve collection and analysis of bear scats and will be supplemented by direct observation of bears in the field. Where feeding or other sign (e.g., mark tree, digging, tracks) site investigations will be carried carried out involving recording inventory, cover value and phenology of all potential bear foods present and taking measurements pertinent...


Investigation of Distribution and Range Boundaries for Some Common Subarctic Inscects Occuring at or Near Treeline
chercheur principal: Royer, Ronald A.
Année(s) de permis: 1995
Résumé: The researcher will investigate range boundaries and species intergrade zones. The researcher will also possibly define ecological limiting factors for selected apecies of common arctic insects, principally in the order of Lepidoptera. This data will fill numerous gaps in understanding of distribution and speciation for the targeted species, the ranges of many of which are assumed but not yet co...


Paleontology & Sedimentology of Late Proterozoic Reefs, Mackenzie Mountains, NWT.
chercheur principal: Narbonne, Guy
Année(s) de permis: 2001 1999 1998 1996 1994 1992 1991 1989 1988
Résumé: Field work will involve detailed measurement & description of stratigraphic sections using a range pole and compass, and mapping and selective sampling of reefs using a geological hammer. Follow-up work at Queen's University will involve analysis of field data and examination of samples using a variety of laboratory techniques. These reefs are an ecological "missing link" between the two major re...


Biogeochemistry of Lakes in the Mackenzie Delta
chercheur principal: Lesack, Lance
Année(s) de permis: 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Résumé: Researchers will evaluate the spatial variability of nutrient chemistry during the snowmelt period within the drainage network of the tundra stream ecosystem. Evaluation of the controls on nutrient chemistry and community metabolism in streams withing the borel forest/tundra ecotone through the measurement of algae and organic matter in the stream. Evaluation of the potential role of Mackenzie De...


Northern River Basins Study Traditional Knowledge Documentation Project
chercheur principal: Bill, Lea
Année(s) de permis: 1994
Résumé: The primary focus of this study will be on the older population (65 years and older). Data on traditional knowledge will be collected by interviews, survey questionnaire, and audio and video taping. Information gathered will be used to document the history of traditional ecological knowledge and to demonstrate the value of traditional ecological knowledge in scientific research and in predictions ...


Inuit ecological knowledge as expressed through place names in the arctic
chercheur principal: Rodin, Rachel
Année(s) de permis: 1994
Résumé: Sites will be selected in the Repulse Bay area whose Inuit place names reflect the biological, physical or cultural/historical significance of the locations. Through visits to these sites and consultation with community members, I will determine the relationship between place names and environmental conditions. Sites will be selected using the Keewatin Nuna-top database of place names....


Environmental study of the aquatic resources of the Thonokeid Lake area
chercheur principal: Couture, Richard
Année(s) de permis: 1994 1994 1993
Résumé: The researchers of Rescan have been contracted by B.H.P. Minerals Canada Ltd. to conduct an assessment of the types of fish and other aquatic organisms that are found in the Thonokeid Lake area. Tissue samples will be collected in order to assess heavy metal contaminants in fish. An environmental report will be submitted to the Territorial Government on the results of this study....
