Public Attitudes and Awareness of Climate Change in the NWT
chercheur principal: Little, Lois M.
Année(s) de permis: 2001
Résumé: The project is being conducted by Lutra Associates Ltd. for the Arctic Energy Alliance. To provide a proper context for taking action on greenhouse gas emissions, the AEA wishes to ascertain information on the knowledge and attitudes amount youth in grades 5-12 about global warming and climate change. The Arctic Energy Alliance's survey of youth is designed to answer questions on climate change is...

Emission of Biogenic Volatile Organic Compounds from Western-Canadian Tundra During the Autumn Freeze-up Period.
chercheur principal: Huffman, Bill
Année(s) de permis: 2000
Résumé: It is proposed that about 12 air samples would be collected into 6 liter stainless steel canisters using a small (<10kg) battery powered air sampler. Additionally, a 0.5 cubic meter open-bottom PVC chamber would be placed on the tundra for a period of 4-6 hours. Air would be sampled from the chamber periodically to establish biogenic emmission rates of n-butanol and other volatile organic compo...

Pealand-Permafrost Mapping and Environmental Implications.
chercheur principal: Kettles, Inez
Année(s) de permis: 1994
Résumé: The researcher will map the configuration of peat deposits and permafrost within them using geophysical surveys (ground penetrating radar and EM-31). This will involve setting out a traverse line on foot using measuring tape and flagging tape, taking measurements along the traverse line with hand-held equipment and measuring the depth of peat using a probe. The researcher will drive or fly out ...

Fire, carbon budget and climate change
chercheur principal: Wein, Ross
Année(s) de permis: 1993
Résumé: The research team will be examining areas of permafrost south of Inuvik and near Hay River in order to assess the rate of loss of permafrost as a result of the warming in climate over the past twenty years. The loss in permafrost may be speeded up following a local fire. The wetlands that replace these areas of permafrost could lead to a greater production of methane (one of the gases that contr...
