要旨

The method to purify air is a basic technique in the measurements of gas exchange in ecosystems. Common several methods of the purification are illustrated and a purification system run in my laboratory is introduced in this presentation.

Understory CO2 and energy fluxes of a black spruce forest Hiroki IKAWA

要旨

I would like to introduce my work in the past few years as a post-doctoral researcher at the International Arctic Research Center, University of Alaska Fairbanks. Understory is one of the least understood components in carbon cycle in the high northern latitude regions. To quantify the understory CO2 and energy fluxes and understand their environmental responses, eddy covariance (EC) measurements were performed above and within the canopy of a black spruce forest in interior Alaska. Gross primary productivity and evapotranspiration measured within the canopy were 80% and 100% of those measured above the canopy in 2011-2013. Because half the plant mass was allocated below the EC system within the canopy, our conservative estimates are that the understory contributed to 60% and nearly 100% of gross primary productivity and evapotranspiration of the ecosystem, respectively.
