Objective(s): To continue year-round eddy covariance measurements of carbon, water and energy fluxes at Trail Valley Creek and Havikpak Creek, established in 2013.

Project Description: 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 open-path infra-red gas analyzer and a sonic anemometer. These measurements are supported by measurements of net radiation, photosynthetically active radiation, soil moisture and temperature, snow depth, air temperature and relative humidity, etc. to aid in the post-processing and interpretation of the eddy covariance measurements. The project is in an excellent position to make use of a well-established network of different avenues regarding knowledge transfer to northern Aboriginal communities. Special emphasis needs to be put on the Wildfrid Laurier University (WLU)-Government of the Northwest Territories (GNWT)-Partnership Agreement and its dedicated Community Liaison. Through this link numerous outlets have been used in the past to communicate research results obtained by Dr. Oliver Sonnentag and his research team to individuals and communities in the NWT: Tusaayaksat Magazine (spring 2016), ClimateWire (2/23/2016), Scientific American (11/19/2015), TVA Nouvelles (11/18/2014), Moose FM (10/23/2014), Deh Cho Drum (9/4/2014), Inuvik Drum (7/31/2014), Deh Cho Drum (9/5/2013). In August 2021, Trail Valley Creek was visited by an ICI Radio Canada production team to interview group members for a documentary on climate change impacts in northwestern Canada. The fieldwork for this study will be conducted from June 1, 2022 to September 15, 2022
