Controls on carbon and nutrient cycling in arctic tundra
chercheur principal: Grogan, Paul
Année(s) de permis: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008
Résumé: The goal of this research over the next five years is to substantially advance the understanding of how Canadian arctic tundra ecosystems function, and therefore how they are likely to be affected by perturbations such as climate change, resource development and extraction, and atmospheric pollution. Specifically, the research team will focus on the impacts on vegetation due to warmer summer tempe...

Soil Carbon in the Mackenzie Delta Region
chercheur principal: Phillips, Marcus R
Année(s) de permis: 2015 2014 2013
Résumé: The goal of this research is to understand how landscape processes influence the quantity and quality of soil carbon in the Mackenzie Delta Region. Particular attention will be paid to the depth distribution of soil carbon and how it is affected by differences in vegetation and soil forming processes. Key environmental differences that will be examined include forest vs. tundra and delta vs. uplan...

Canadian Tundra Carbon Exchange Project
chercheur principal: Lafleur, Peter M
Année(s) de permis: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2007 2005 2004
Résumé: The research being carried out at Daring Lake, NWT involves researchers being on-site for extended periods of time, monitoring automatic instruments and making manual measurements. Carbon dioxide exchange measurements made at the ecosystem level will be done with equipment installed on a small tower and located a few meters over the tundra surface. The tower equipment will also measure various met...

Environmental Soil Chemistry at Abandoned Drilling Mud-Sumps in the Kendall Island Bird Sanctuary, Mackenzie Delta Region
chercheur principal: Biggar, Kevin
Année(s) de permis: 2006 2005
Résumé: Since the 1970s, the oil and gas industry has drilled at least nineteen exploratory wells in the Kendall Island Bird Sanctuary. Observations at associated drilling mud-sumps have been made; however, there remains a paucity of field data describing site conditions. It is also appreciated that construction of the proposed Mackenzie Valley pipeline will stimulate the development of Niglintgak and Tag...
