Objectif(s): To continue the year-round eddy covariance measurements of carbon, water and energy fluxes at Scotty Creek.

Description du projet: The project of the present application is the continuation of year-round eddy covariance measurements of carbon, water and energy fluxes at Scotty 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 and transfer to northern Aboriginal communities. 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). The fieldwork for this study will be conducted from June 1, 2018 to November 30, 2018.
