Quantifying carbon fluxes and budgets of boreal forest-tundra landscapes under the influence of rapidly changing permafrost regimes
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2022 2021 2019 2018 2017 2016 2015 2014 2013
Summary: Through this project the principal investigator will address the following objectives: What is the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system? How do these two types of feedback differ between the discontinuous and continuous permafrost zones? Is the reported decrease (increase) in net Carbon Dioxide (CO2)-Methane (CH4) exchange based on...

Geological carbon in the Mackenzie River Basin: Sources and sinks of atmospheric carbon dioxide
Principal Investigator: Hilton, Robert G
Licensed Year(s): 2017 2013 2011 2010 2009
Summary: The objective of this study are to quantify the amount of chemical weathering that takes place in the Mackenzie River Basin, to quantify how much weathering of silicate rocks is done by carbonic acid versus sulfuric acid, and to quantify the chemical weathering of fossil organic carbon. The overall aim is therefore to assess the carbon balance of the whole river basin and to place constraints on ...

Structure and Carbon Dynamics of Boreal Forests in Discontinuous and Continuous Permafrost Zones
Principal Investigator: Osawa, Akira
Licensed Year(s): 2019 2018 2016 2015 2013 2012 2011 2010 2009 2008 2007 2006
Summary: The possibility of climate warming demands detailed analysis of the carbon budget in boreal forest ecosystems as they may be major carbon sinks. The data from previous years suggest that forests may be losing carbon to the atmosphere. Due to large annual variation in carbon accumulation, measurements covering several years are necessary. Soil and air temperature, and soil moisture will be meas...

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 issue of global warming because they are likely to absorb much of the carbon dioxide that is emitted into the air by humans. The amount that these forests absorb, however, is not clear. The main objectives of the 2005 field season are to collect data on the annual growth of fine roots, and to further examine the rate of soil respiration. Both of these...

Canadian Tundra Climate Exchange Project
Principal Investigator: Lafleur, Peter M

Organic Carbon Dynamics and Accumulation in Discontinuously Frozen Peatlands
Principal Investigator: Robinson, Stephen
Licensed Year(s): 1996 1995
Summary: Research will be conducted in a fen-bog complex approximately 5 km west of Fort Simpson. Gas samples will be obtained using portable chambers and later analyzed using gas chromotography. Cores will be collected using a peat corer and a modified ice auger. Peat temperatures, water levels, plant growth rates and water chemistry will also be measured. Geophysical mapping using ground penetrating ...
