Carbon dynamics in chronosequence of boreal forest ecosystems: a production ecological approach
Principal Investigator: Osawa, Akira
Licensed Year(s): 2017 2005 2004 2003 2002 2001
Summary: Northern forests are closely connected to the problem of global warming because they are likely to absorb much of the carbon dioxide that is dumped into the air by humans. The amount that these forests are absorbing, however, is not clear. The research w...

Physical properties of dead and downed round-wood in the boreal forests of Western Canada
Principal Investigator: Wein, Ross
Licensed Year(s): 2002
Summary: Accurate estimates of the bulk density or specific gravity, tilt angle and average diameter of various size classes must be established. This study focuses on collection and validation of these estimates, recognizing that they may indeed change, dependin...

Permafrost investigations in western Arctic Canada
Principal Investigator: Burn, Chris R
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Summary: The researcher will measure changes in ground temperatures by data loggers and on ground temperature cables that were installed several years ago. The researcher will measure both uplift of the ground by surveying, and sideways movement of the ground due to growth of ice wedges. The researcher will also measure air, ground, and lake water temperatures and ice thickness, to find out how these a...

Post-fire decomposition of woody material and post-fire habitat structures in the western Canadian boreal forest.
Principal Investigator: Sander, Barbara
Licensed Year(s): 1997
Summary: Burned areas of different ages have been identified from fire-history maps and data bases provided by the Forest Management Division of the NWT in Fort Smith. Chosen fires are located along the Highways 1, 2 and 5. Access and transportation will therefore be by car/truck. The exact location of the sites will be documented by using GPS-equipment. A total of three sites (Jack Pine, Black Spruce ...
