Using digital camera and Landsat imagery with eddy covariance data to model gross primary production in restored wetlands
Knox, Sara Helen Dronova, Iryna Sturtevant, Cove Oikawa, Patricia Y. Matthes, Jaclyn Hatala Verfaillie, Joseph Baldocchi, Dennis

Wetlands have the ability to accumulate large amounts of carbon (C), and therefore wetland restoration has been proposed as a means of sequestering atmospheric carbon dioxide (CO2) to help mitigate climate change. There is a growing interest in using the C services of wetlands to help reduce habitat loss and finance restoration projects. …

The 2013 Flex—Us Airborne Campaign At The Parker Tract Loblolly Pine Plantation In North Carolina, Usa
Middleton, E., Rascher, U., Corp, L., Huemmrich, K., Cook, B., Noormets, A., Schickling, A., Pinto, F., Alonso, L., Damm, A., Guanter, L., Colombo, R., Campbell, P., Landis, D., Zhang, Q., Rossini, M., Schuettemeyer, D., Bianchi, R.

The first European Space Agency (ESA) and NASA collaboration in an airborne campaign to support ESA’s FLuorescence EXplorer (FLEX) mission was conducted in North Carolina, USA during September-October 2013 (FLEX-US 2013) at the Parker Tract Loblolly Pine (LP) Plantation (Plymouth, NC, USA). This campaign combined two unique airborne …

Association With Pedogenic Iron And Aluminum: Effects On Soil Organic Carbon Storage And Stability In Four Temperate Forest Soils
Porras, R. C., Hicks Pries, C. E., McFarlane, K. J., Hanson, P. J., Torn, M. S.

Soil organic carbon (SOC) can be stabilized via association with iron (Fe) and aluminum (Al) minerals. Fe and Al can be strong predictors of SOC storage and turnover in soils with relatively high extractable metals content and moderately acidic to circumneutral pH. Here we test whether pedogenic Fe and Al influence SOC content and …

Annual greenhouse gas budget for a bog ecosystem undergoing restoration by rewetting
Lee, S.-C., Christen, A., Black, T.A., Johnson, M.S., Jassal, R.S., Ketler, R., Nesic, Z., Merkens, M.

Many peatlands have been drained and harvested for peat mining, agriculture, and other purposes, which has turned them from carbon (C) sinks into C emitters. Rewetting of disturbed peatlands facilitates their ecological recovery and may help them revert to carbon dioxide (CO2) sinks. However, rewetting may also cause substantial …

Direct And Indirect Climate Change Effects On Carbon Dioxide Fluxes In A Thawing Boreal Forest-Wetland Landscape
Helbig, M., Chasmer, L. E., Desai, A. R., Kljun, N., Quinton, W. L., Sonnentag, O.

In the sporadic permafrost zone of northwestern Canada, boreal forest carbon dioxide (CO2 ) fluxes will be altered directly by climate change through changing meteorological forcing and indirectly through changes in landscape functioning associated with thaw-induced collapse-scar bog (‘wetland’) expansion. However, their combined …

Revisiting the partitioning of net ecosystem exchange of CO2 into photosynthesis and respiration with simultaneous flux measurements of 13CO2 and CO2, soil respiration and a biophysical model, CANVEG.
Oikawa, P. Y., C. Sturtevant, S. H. Knox, J. Verfaillie, Y. W. Huang, and D. D. Baldocchi.

The partitioning of net ecosystem exchange of CO(NEE) into photosynthesis and respiration can be challenging and is often associated with assumptions that yield unknown amounts of uncertainty, thereby hindering model development. This occurs because we are inferring two pieces of information from one equation and measurement, …

Evaluation Of Density Corrections To Methane Fluxes Measured By Open-Path Eddy Covariance Over Contrasting Landscapes
Chamberlain, S. D., Verfaillie, J., Eichelmann, E., Hemes, K. S., Baldocchi, D. D.

Corrections accounting for air density fluctuations due to heat and water vapour fluxes must be applied to the measurement of eddy-covariance fluxes when using open-path sensors. Experimental tests and ecosystem observations have demonstrated the important role density corrections play in accurately quantifying carbon dioxide ( CO …

Inter-Annual Variability Of Net And Gross Ecosystem Carbon Fluxes: A Review
Baldocchi, D., Chu, H., Reichstein, M.

As the lifetime of regional flux networks approach twenty years, there is a growing number of papers that have published long term records (5 years or more) of net carbon fluxes between ecosystems and the atmosphere. Unanswered questions from this body of work are: 1) how variable are carbon fluxes on a year to year basis?; 2) what …

Delta-Flux: An Eddy Covariance Network for a Climate-Smart Lower Mississippi Basin
Benjamin R. K. Runkle, James R. Rigbyb, Michele L. Rebac, Saseendran S. Anapallid, Joydeep Bhattacharjeee, Ken W. Kraussf, Lu Liangg, Martin A. Locke, Kimberly A. Novick, Ruixiu Suid, Kosana Suvočareva and Paul M. White

Networks of remotely monitored research sites are increasingly the tool used to study regional agricultural impacts on carbon and water fluxes. However, key national networks such as the National Ecological Observatory Network and AmeriFlux lack contributions from the Lower Mississippi River Basin (LMRB), a highly productive agricultural …
