Fluvial Carbon Export From A Lowland Amazonian Rainforest In Relation To Atmospheric Fluxes
Vihermaa, L. E., Waldron, S., Domingues, T., Grace, J., Cosio, E. G., Limonchi, F., Hopkinson, C., da Rocha, H. R., Gloor, E.

We constructed a whole carbon budget for a catchment in the Western Amazon Basin, combining drainage water analyses with eddy covariance (EC) measured terrestrial CO2 fluxes. As fluvial C export can represent permanent C export it must be included in assessments of whole site C balance, but it is rarely done. The footprint area of …

Slow ecosystem responses conditionally regulate annual carbon balance over 15 years in Californian oak-grass savanna
Ma, S, Baldocchi, D.D., Wolf, S., Verfaillie, J.

Many ecophysiological and biogeochemical processes respond rapidly to changes in biotic and abiotic conditions, while ecosystem-level responses develop much more slowly (e.g., over months, seasons, years, or decades). To better understand the role of the slow responses in regulating interannual variability in NEE, we partitioned …

Closing The Water Balance With Cosmic-Ray Soil Moisture Measurements And Assessing Their Relation To Evapotranspiration In Two Semiarid Watersheds
Schreiner-McGraw, A. P., Vivoni, E. R., Mascaro, G., Franz, T. E.

Soil moisture dynamics reflect the complex interactions of meteorological conditions with soil, vegetation and terrain properties. In this study, intermediate-scale soil moisture estimates from the cosmic-ray neutron sensing (CRNS) method are evaluated for two semiarid ecosystems in the southwestern United States: a mesquite savanna …

Comparison Of Net Ecosystem Carbon Exchange Estimation In A Mixed Temperate Forest Using Field Eddy Covariance And Modis Data

The contribution of an overlooked transport process to a wetland’s methane emissions.
Poindexter, C. M., D. D. Baldocchi, J. H. Matthes, S. H. Knox, and E. A. Variano.

Wetland methane transport processes affect what portion of methane produced in wetlands reaches the atmosphere. We model what has been perceived to be the least important of these transport processes: hydrodynamic transport of methane through wetland surface water and show that its contribution to total methane emissions from a temperate …

How Many Measurements Are Needed To Estimate Accurate Daily And Annual Soil Respiration Fluxes? Analysis Using Data From A Temperate Rainforest
Perez-Quezada, J. F., Brito, C. E., Cabezas, J., Galleguillos, M., Fuentes, J. P., Bown, H. E., Franck, N.

Making accurate estimations of daily and annual Rs fluxes is key for understanding the carbon cycle process and projecting effects of climate change. In this study we used high-frequency sampling (24 measurements per day) of Rs in a temperate rainforest during 1 year, with the objective of answering the questions of when and how …

Earlier Snowmelt Reduces Atmospheric Carbon Uptake In Midlatitude Subalpine Forests
Winchell, T. S., Barnard, D. M., Monson, R. K., Burns, S. P., Molotch, N. P.

Previous work demonstrates conflicting evidence regarding the influence of snowmelt timing on forest net ecosystem exchange (NEE). Based on 15 years of eddy covariance measurements in Colorado, years with earlier snowmelt exhibited less net carbon uptake during the snow ablation period, which is a period of high potential for productivity. …

CALIBRATION OF SOIL WATER CONTENT MEASUREMENTS OBSERVED WITH CAPACITANCE PROBES
Curto, L., Covi M., Gassmann, M.I.

Soil moisture or soil water content is an important variable for Meteorology,
Agronomy, Hydrology and Soil Science. In Argentina, measurements of soil
moisture are both spatially and temporally sparsely distributed. There are different
methodologies of measuring soil moisture content like the gravimetric, neutron and
dielectric …
