Evaporation from Lake Superior: 1. Physical controls and processes

The surface energy balance of Lake Superior was measured using the eddy covariance method at a remote, offshore site at 0.5-h intervals from June 2008 through November 2010. Pronounced seasonal patterns in the surface energy balance were observed, with a five-month delay between maximum summer net radiation and maximum winter latent …

Quick recovery of carbon dioxide exchanges in a burned black spruce forest in interior Alaska
Iwata, H., Ueyama, M., Harazono, Y., Tsuyuzaki, S., Kondo, M., Uchida, M.

Observations of carbon dioxide (CO2) flux with the eddy covariance technique were conducted at a burned boreal forest site five years after a wildfire and at a mature forest site in Interior Alaska to investigate the effects of wildfire on CO2 exchange in a boreal forest. Both gross primary productivity and ecosystem respiration …

Evapotranspiration over Spatially Extensive Plant Communities in the Big Cypress National Preserve, Southern Florida, 2007–2010
W. Barclay Shoemaker

Evapotranspiration (ET) was quantified over plant communities within the Big Cypress National Preserve (BCNP) using the eddy covariance method for a period of 3 years from October 2007 to September 2010. Plant communities selected for study included Pine Upland, Wet Prairie, Marsh, Cypress Swamp, and Dwarf Cypress. These plant communities …

The Influence Of Carbon Exchange Of A Large Lake On Regional Tracer-Transport Inversions: Results From Lake Superior
Vasys, V. N., Desai, A. R., McKinley, G. A., Bennington, V., Michalak, A. M., Andrews, A. E.

Large lakes may constitute a significant component of regional surface–atmosphere fluxes, but few efforts have been made to quantify these fluxes. Tracer-transport inverse models that infer the CO2 flux from the atmospheric concentration typically assume that the influence from large lakes is negligible. CO2

The Relative Controls Of Temperature, Soil Moisture, And Plant Functional Group On Soil CO2 Efflux At Diel, Seasonal, And Annual Scales
Barron-Gafford, G.A., Scott, R.L., Jenerette, G.D., Huxman, T.E.

Soil respiration (Rsoil) is a dominant, but variable, contributor to ecosystem CO2 efflux. Understanding how variations in major environmental drivers, like temperature and …

Seasonal And Interannual Variability In 13c Composition Of Ecosystem Carbon Fluxes In The U.S. Southern Great Plains
Torn, M. S., Biraud, S. C., Still, C. J., Riley, W. J., Berry, J. A.

The δ13C value of terrestrial CO2 fluxes (δbio) provides important information for inverse models of CO2 sources and sinks as well as for studies of vegetation physiology, C3 and C4 vegetation fluxes, and ecosystem carbon residence times. From 2002.2009, we measured atmospheric CO2 concentration and δ13C-CO2 at four heights (2 …

Evaporation From Lake Superior: 2 Spatial distribution and variability
Spence, C., Blanken, P., Hedstrom, N., Fortin, V., Wilson, H.

Evaporation is a critical component of the water balance of each of the Laurentian Great Lakes, and it is expected that because of their shear size, evaporation cannot be spatially or temporally uniform. Despite this, examples of spatially distributed estimates of evaporation in the scientific literature are rare for most of the …

Evidence Of Increased Net Ecosystem Productivity Associated With A Longer Vegetated Season In A Deciduous Forest In South-Central Indiana, Usa
DRAGONI, D., SCHMID, H. P., WAYSON, C. A., POTTER, H., GRIMMOND, C. S., RANDOLPH, J. C.

Observations of net ecosystem exchange (NEE) of carbon and its biophysical drivers have been collected at the AmeriFlux site in the Morgan-Monroe State Forest (MMSF) in Indiana, USA since 1998. Thus, this is one of the few deciduous forest sites in the world, where a decadal analysis on net ecosystem productivity (NEP) trends is …

Seasonal Pattern Of Regional Carbon Balance In The Central Rocky Mountains From Surface And Airborne Measurements
Desai, A.R., Moore, D.J.P., Ahue, W.K.M., Wilkes, P.T.V., De Wekker, S.F.J., Brooks, B.G., Campos, T.L., Stephens, B.B., Monson, R.K., Burns, S.P., Quaife, T., Aulenbach, S.M., Schimel, D.S.

High-elevation forests represent a large fraction of potential carbon uptake in North America, but this uptake is not well constrained by observations. Additionally, forests in the Rocky Mountains have recently been severely damaged by drought, fire, and insect outbreaks, which have been quantified at local scales but not assessed …
