Year Of Methane At The AmeriFlux 2019 Annual Meeting ...

Finally, the Powell activity is pursuing synthesis work spread across two workshops, the second of which will be held in February 2020. The activity is already generating exciting results, including the characterization of seasonal hysteresis in methane temperature dependencies and identifying the direction and timescale of methane driver ...

We all know the importance of soil as a CO2 source to the atmosphere, even in high latitude/altitude ecosystems with persistent snow cover. Before the days of automated soil respiration chambers and accessible eddy covariance technology, CO2 fluxes through porous media were estimated using vertical CO2 concentration profiles coupled with assumption that …

Environmental And Biological Controls On Water And Energy ...

Authors: Bracho, R.; Powell, T. L.; Dore, S.; Li, J.; Hinkle, C. R.; Drake, B. G. Scrub oak and pine flatwoods are two contrasting ecosystems common to the humid subtropical climate of Florida. Scrub oak forests are short in stature (<2 m) and occur on well-drained sandy soils, and pine flatwoods are much taller and occur in areas with poorly ...

Environmental Controls Over Net Ecosystem Carbon Exchange ...

Biological and physical controls regulating variation of seasonal and interannual ecosystem carbon exchange in a scrub oak ecosystem in central Florida were determined by measuring net ecosystem exchange of CO 2 (NEE) between the atmosphere and vegetation using the eddy covariance technique continuously for 6 years (April 2000–March 2006). Total net ecosystem …

Eddy covariance was used to measure energy fluxes from July 2000 – June 2002 above the tree canopy and above the understory in a mature, naturally regenerated slash pine (Pinus elliottii Engelm. var. elliottii) – longleaf pine (Pinus palustris Mill.) flatwoods forest.Understory latent energy (λE) and sensible heat (H) fluxes accounted for 45% and 55% of whole-ecosystem …
