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: This licence has been issued for the scientific research application No.5220. The project of the present application is the continuation of year-round eddy covariance measurements of carbon, water and energy fluxes at Trail Valley Creek and Havikpak Creek, established in 2013. The key methodology is tower-mounted micrometeorological measurements around the eddy covariance technique using an ...


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...


O-buoy measurements of ozone, carbon dioxide and bromine oxide over frozen surface of Hudson Bay and Arctic Ocean
Principal Investigator: Bottenheim, Jan W
Licensed Year(s): 2012 2011 2010
Summary: The goal of this project is to take part in establishment of a long-term observation network to measure concentrations of two important greenhouse gases (ozone and carbon dioxide) as well as bromine oxide. Bromine oxide is a key chemical reagent determining the presence of ozone accompanied with full set of meteorological data and detailed geographic information across the Arctic Ocean and Hudson ...


Recent changes in carbon source-sink relationships and greenhouse gas emissions in forest and peatland ecosystems along the Mackenzie Valley region of Canada
Principal Investigator: Bhatti, Jagtar
Licensed Year(s): 2011 2010 2009 2008 2007
Summary: The objectives of this research project are to: 1. map and assess changes in the distribution and composition of forest and peatland ecosystems due to climate changes; 2. estimate carbon storage (and variation) in boreal to arctic ecoregions of the Mackenzie valley; and 3. assess interannual and seasonal variations and key processes controlling carbon dioxide (CO2) and methane (CH4) dynamics. ...


Emission of Biogenic Volatile Organic Compounds from Western-Canadian Tundra During the Autumn Freeze-up Period.
Principal Investigator: Huffman, Bill
Licensed Year(s): 2000
Summary: It is proposed that about 12 air samples would be collected into 6 liter stainless steel canisters using a small (<10kg) battery powered air sampler. Additionally, a 0.5 cubic meter open-bottom PVC chamber would be placed on the tundra for a period of 4-6 hours. Air would be sampled from the chamber periodically to establish biogenic emmission rates of n-butanol and other volatile organic compo...


Pealand-Permafrost Mapping and Environmental Implications.
Principal Investigator: Kettles, Inez
Licensed Year(s): 1994
Summary: The researcher will map the configuration of peat deposits and permafrost within them using geophysical surveys (ground penetrating radar and EM-31). This will involve setting out a traverse line on foot using measuring tape and flagging tape, taking measurements along the traverse line with hand-held equipment and measuring the depth of peat using a probe. The researcher will drive or fly out ...
