Permafrost regions in transition: controls on carbon cycling and greenhouse gas emissions
Principal Investigator: Wookey, Philip A
Licenced Year(s): 2014 2013
Summary: 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...


Quantifying carbon fluxes and budgets of boreal forest-tundra landscapes under the influence of rapidly changing permafrost regimes
Principal Investigator: Sonnentag, Oliver
Licenced Year(s): 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
Licenced Year(s): 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
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001
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...


Canadian Tundra Climate Exchange Project
Principal Investigator: Lafleur, Peter M
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2007 2005 2004
Summary: The purpose of this study is to examine carbon exchange between the arctic tundra and the atmosphere. Specifically, the researchers are interested in variation in carbon exchange in response to environmental factors such as soil moisture and weather (tem...


Studies on the past, present and future ecological impact on Canadian northern boreal forest and arctic ecosystems due to mining activities, shown at the Great Slave Lake area, Northwest Territories, Canada
Principal Investigator: Steinecke, Karin
Licenced Year(s): 1998 1997
Summary: The project will focus on understanding, analyzing and evaluating the reactions of the northern boreal forest ecosystems in the Great Slave Lake region due to man made stress of mining, settlement and connecting activities. The project will try to develop some general conclusions, statements and model systems. The research team (2 persons) will come from Europe to Yellowknife by plane. The base wi...


Organic Carbon Accumulation in discontinuously frozen peatlands
Principal Investigator: Robinson, Stephen
Licenced Year(s): 1996 1995
Summary: Research will be conducted in a peatland complex approximately 12 km west of Fort Simpson (4 km west of the Wrigley Road). The major component of the field work will include the collection of peat cores in both frozen and unfrozen terrain to about 1 m depth. A total of approximately 100 cores will be collected. Core holes will be approximately 15 cm wide, and will be filled to minimize terrain ...
