To what extent will nitrogen limit Canadian boreal forest growth and the terrestrial carbon sink under global change?
Principal Investigator: Kou-Giesbrecht, Sian
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5951. The overarching objective of this research is to understand the extent to which nutrients will limit forest growth and terrestrial carbon sequestration in Canadian boreal forests and to improve how this is represented in climate change models. These climate change models can then be used to understand the impacts of ...

Erosion of old organic carbon in the Mackenzie River Basin
Principal Investigator: Hilton, Robert G
Licensed Year(s): 2020 2019
Summary: This licence has been issued for the scientific research application No.4678. The research team will collect a new sample set to better quantify the carbon source, age and fate in one of the largest rivers draining the high latitudes. Based on previous work, the team have identified three priority objectives for sample collection in the Mackenzie River: 1) Collect river depth profile sediment ...

Understanding the Interactions between Wildfire Disturbance, Landscape Hydrology and Post-Fire Recovery in Boreal-Taiga Ecosystems
Principal Investigator: Bourgeau-Chavez, Laura L.
Licensed Year(s): 2019
Summary: The overall goal of the research is to improve understanding of the controls and impacts of a changing climate on the vulnerability and resiliency of boreal-taiga ecosystems to wildfire. This is being addressed through field sampling and process-based ecological and hydrological modeling of the 2014-2016 wildfires of southern NWT. To conduct the proposed research, the research team will addres...

Permafrost regions in transition: controls on carbon cycling and greenhouse gas emissions
Principal Investigator: Wookey, Philip A
Licensed 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
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...
