Age Effects On The Water-Use Efficiency And Water-Use Dynamics Of Temperate Pine Plantation Forests
Skubel, R., Arain, M. A., Peichl, M., Brodeur, J. J., Khomik, M., Thorne, R., Trant, J., Kula, M.

This study analyzed age-related water use dynamics across three temperate conifer forest plantations (aged 11-, 39-, and 74-years old, as of 2013, henceforth referred to as TP02, TP74, and TP39, where the last two digits represent the year of planting) in southern Ontario, Canada from 2008 to 2013. Eddy covariance-measured mean evapotranspiration …

Growing season eddy covariance measurements of carbonyl sulfide and CO2 fluxes: COS and CO2 relationships in Southern Great Plains winter wheat
Billesbach,D.P., Berry,J.A., Seibt,U., Maseyk,K., Torn,M.S., Fischer,M.L., Abu-Naserg,M., Campbell,J.E.

To test the capabilities of newly available instrumentation and to explore the dynamics of carbonyl sulfide(COS) as a proxy for the measurement of canopy-scale gross primary production (GPP), we conducted an experiment to measure the simultaneous net transfer of COS and CO2 between the atmosphere and a growing wheat canopy, senesced …

Measuring Fluxes of Trace Gases and Energy between Ecosystems and the Atmosphere—the State and Future of the Eddy Covariance Method
Baldocchi, D.

The application of the eddy covariance flux method to measure fluxes of trace gas and energy between ecosystems and the atmosphere has exploded over the past 25 years. This opinion paper provides a perspective on the contributions and future opportunities of the eddy covariance method. First, the paper discusses the pros and cons …

Agricultural peatland restoration: effects of land-use change on greenhouse gas (CO2 and CH4) fluxes in the Sacramento-San Joaquin Delta
Knox, S. H.,, Sturtevant, C., Matthes, J.H., Koteen, L., Verfaillie,J., Baldocchi. D.

Agricultural drainage of organic soils has resulted in vast soil subsidence and contributed to increased atmospheric carbon dioxide (CO2) concentrations. The Sacramento-San Joaquin Delta in California was drained over a century ago for agriculture and human settlement and has since experienced subsidence rates that are among the …

An improved approach for remotely sensing water stress impacts on forest C uptake
Sims, D.A., Brzostek, E.R., Dragoni, D., Rahman, A.F., Phillips, R.P.

Given that forests represent the primary terrestrial sink for atmospheric CO2, projections of future carbon (C) storage hinge on forest responses to climate variation. Models of gross primary production (GPP) responses to water stress are commonly based on remotely sensed changes in canopy ‘greenness’ (e.g., normalized difference …

Species-specific transpiration responses to intermediate disturbance in a northern hardwood forest
Matheny, A.M. Bohrer, G. Vogel, C.S. Morin, T.H. He, L. Frasson, R.P.dM. Mirfenderesgi, G. Schäfer, K.V.R. Gough, C.M. Ivanov, V.Y. Curtis, P.S.

Intermediate disturbances shape forest structure and composition, which may in turn alter carbon, nitrogen, and water cycling. We used a large-scale experiment in a forest in northern lower Michigan where we prescribed an intermediate disturbance by stem girdling all canopy-dominant early successional trees to simulate an accelerated …

Environmental drivers of methane fluxes from an urban temperate wetland park
Morin, T.H. Bohrer, G. Frasson, R.P.dM. Naor-Azrieli, L. Mesi, S. Stefanik, K.C. Schäfer, K.V.R.

Methane (CH4) emissions were measured at the Wilma H. Schiermeier Olentangy River Wetland Research Park (ORWRP) over three summers and two winters using an eddy covariance system. We used an empirical model to determine the main environmental drivers of methane emissions. Methane emissions covary strongly with water vapor fluxes, …

The seasonal and diurnal dynamics of methane flux at a created urban wetland
Morin, T.H. Bohrer, G. Naor-Azrieli, L. Mesi, S. Kenny, W.T. Mitsch, W.J. Schäfer, K.V.R.

Wetlands provide important ecosystem services and store carbon dioxide but are also an important global source of methane – a potent greenhouse gas. In order to understand the dynamics of methane emissions from a temperate reconstructed wetland, methane fluxes were measured continuously over 2 years using the eddy covariance method …
