Landscape-Scale Variability In Soil Organic Carbon Storage In The Central Canadian Arctic
Campeau, A. B., Lafleur, P. M., Humphreys, E. R.

Campeau, A. B., Lafleur, P. M. and Humphreys, E. R. 2014. Landscape-scale variability in soil organic carbon storage in the central Canadian Arctic. Can. J. Soil Sci. 94: 477–488. Arctic soils constitute a vast, but poorly quantified, pool of soil organic carbon (SOC). The uncertainty associated with pan-Arctic SOC …

Does Earlier Snowmelt Lead To Greater CO2 Sequestration In Two Low Arctic Tundra Ecosystems?
Humphreys, E. R., Lafleur, P. M.

Some studies have reported that spring warming and earlier snowmelt leads to increased CO2sequestration in Arctic terrestrial ecosystems. We measured tundra-atmosphere CO2 exchange via eddy covariance at two low Arctic sites (mixed upland tundra and sedge fen) in central Canada over multiple snow-free periods …

Spring Warming And Carbon Dioxide Exchange Over Low Arctic Tundra In Central Canada
Lafleur, P.M., Humphreys, E.R.

Tundra-atmosphere exchanges of carbon dioxide (CO2) and water vapour were measured near Daring Lake, Northwest Territories in the Canadian Low Arctic for 3 years, 2004–2006. The measurement period spanned late-winter until the end of the growing period. Mean temperatures during the measurement period varied from about …
