Permafrost regions in transition: controls on carbon cycling and greenhouse gas emissions
chercheur principal: Wookey, Philip A
Année(s) de permis: 2014 2013
Résumé: This research aims to understand what factors affect 1) the amount of carbon stored in tundra soils, and 2) the conversion of this soil carbon into greenhouse gases (carbon dioxide and methane). In particular, the research team wants to understand how hydrology (which is the distribution and movement of water in soils and streams) might affect the carbon cycle under future global warming. This inc...


Arctic Analogues of Utopia and western Elysium Planitia, Mars
chercheur principal: Soare, Richard J
Année(s) de permis: 2009 2007 2006 2005 2004
Résumé: This project’s objective is to take multiple, small .25kg samples of the active layer of permafrost in areas where patterned ground and thermokarst are present. The data gained will help the researchers in their efforts to understand possible cold climate processes in the northern hemisphere of Mars. The researchers intend to visit areas in the vicinity of Inuvik and Tuktoyaktuk where polygonal...


2003 Terrestrial Studies in the Gwich'in Settlement Area
chercheur principal: Povey, Andrew
Année(s) de permis: 2005 2004 2003 2002
Résumé: These terrestrial studies will include vegetation and soils investigations. The primary goals are to classify vegetation, landforms, soils and permafrost in the project area, to identify locations of rare plants and uncommon plant communities in the pro...


Near-surface ground ice in Mackenzie Delta region
chercheur principal: Kokelj, Steven V
Année(s) de permis: 2004 2003 2002 2001 2000 2000 1999
Résumé: The proposed research will investigate the physical and chemical characteristics of the near-surface ice-rich zone in sediments of the Mackenzie Delta area. The goals of the research are to investigate the relationship between ice-rich permafrost and fo...


Active Layer Monitoring Network in the Mackenzie Valley
chercheur principal: Nixon, Mark
Année(s) de permis: 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Résumé: This season, a party of two will survey tubes between Tsiigehtchic and the coast during March and April and from Fort Simpson to the Arctic Coast in July and August. Staff of the Inuvik Research Centre may take late season measurements north and south of Inuvik as part of a cooperative program. Travel will be by road, small boat on the river and helicopter from Inuvik. Access to the sites is alw...


Investigation of ground ice development in sediments of the Mackenzie Delta area
chercheur principal: Burn, Chris R
Année(s) de permis: 1997 1996 1995 1994 1993 1992 1991
Résumé: The researcher will continue to collect samples of ground ice and measure temperatures in lakes and ponds. This information is used to help understand how the ground heaves as it freezes in winter, and to determine the extent of soil settlement during thaw in summer. The information about lakes is used to help understand the relations between water depths and temperatures beneath the lake....


International Cryosol Tour
chercheur principal: Tarnocai, C.
Année(s) de permis: 1991
Résumé: This tour and the associated meetings will focus on the genesis, classification and management of permafrost soils (Cryosols) and the possible effect of climate change on these soils....
