Examining the impacts of climate and environmental change on aquatic and terrestrial ecosystems of the Mackenzie region, NWT
chercheur principal:
Année(s) de permis: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Résumé: This research will continue the long term objective of documenting and understanding the impacts of recent climate change on northern terrestrial and aquatic ecosystems. The short term objectives of my research for 2018 are: 1) to investigate the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems; 2) to examine the limnological implications of drained lakes on ...

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:
Année(s) de permis: 2011 2010 2009 2008 2007
Résumé: The objectives of this research project are to: 1. map and assess changes in the distribution and composition of forest and peatland ecosystems due to climate changes; 2. estimate carbon storage (and variation) in boreal to arctic ecoregions of the Mackenzie valley; and 3. assess interannual and seasonal variations and key processes controlling carbon dioxide (CO2) and methane (CH4) dynamics. ...

Environmental change in the 20th century, Mackenzie Delta region, Northwest Territories
chercheur principal:
Année(s) de permis: 2008 2007 2006 2005
Résumé: The impact of climate change on forest ecosystems in the Mackenzie Delta is being studied using dendrochronology. Earlier studies indicate a negative relationship between tree growth and summer temperatures. Summer temperatures may be exceeding the physiological threshold of northern trees or perhaps the trees are drought stressed. Manual and automatic dendrometers will be used to measure tree gro...

Active Layer Monitoring Network in the Mackenzie Valley
chercheur principal:
Année(s) de permis: 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Résumé: The active layer, overlying the permafrost layer, is the surface earth material that thaws and re-freezes each year. Active layer thickness and character can influence hunting, fishing, forestry, gardening, transportation and construction. Changes in the active layer can contribute to landslides which may damage structures, hamper transportation, affect water quality, and influence surface and sub...

Sustainability of Arctic Communities
chercheur principal:
Année(s) de permis: 1999
Résumé: Part A: "Possible Futures Model". Researchers have constructed models which project how force of change will affect communities in the future, based on local knowledge and research findings of previous studies. In 1998-99, the "Possible Futures Model" will be presented to people of Fort McPherson and Aklavik. The model allows users to consider the effects of changes that may occur in the next 40 ...
