Co2 Exchange And Evapotranspiration Across Dryland Ecosystems Of Southwestern North America
Biederman, J. A., Scott, R. L., Bell, T. W., Bowling, D. R., Dore, S., Garatuza-Payan, J., Kolb, T. E., Krishnan, P., Krofcheck, D. J., Litvak, M. E., Maurer, G. E., Meyers, T. P., Oechel, W. C., Papuga, S. A., Ponce-Campos, G. E., Rodriguez, J. C., Smith, W. K., Vargas, R., Watts, C. J., Yepez, E. A., Goulden, M. L.

Global-scale studies suggest that dryland ecosystems dominate an increasing trend in the magnitude and interannual variability of the land CO2 sink. However, such analyses are poorly constrained by measured CO2 exchange in drylands. Here we address this observation gap with eddy covariance data from 25 sites in the water-limited …

Arctic Regional Methane Fluxes By Ecotope As Derived Using Eddy Covariance From A Low-Flying Aircraft
Sayres, D. S., Dobosy, R., Healy, C., Dumas, E., Kochendorfer, J., Munster, J., Wilkerson, J., Baker, B., Anderson, J. G.

The Arctic terrestrial and sub-sea permafrost region contains approximately 30 % of the global carbon stock, and therefore understanding Arctic methane emissions and how they might change with a changing climate is important for quantifying the global methane budget and understanding its growth in the atmosphere. Here we present …

Trapped Greenhouse Gases In The Permafrost Active Layer: Preliminary Results For Methane Peaks In Vertical Profiles Of Frozen Alaskan Soil Cores
Byun, E., Yang, J., Kim, Y., Ahn, J.

Copyright © 2016 John Wiley & Sons, Ltd.Degradation of organic carbon stored in permafrost may represent an additional source of atmospheric greenhouse gases (GHGs) in a warming climate. However, there is no clear understanding of how seasonal freeze–thaw affects gas permeability and emission of methane in permafrost soils, …

Closing The Scale Gap Between Land Surface Parameterizations And Gcms With A New Scheme, Sib3-Bins
Baker, I. T., Sellers, P. J., Denning, A. S., Medina, I., Kraus, P., Haynes, K. D., Biraud, S. C.

The interaction of land with the atmosphere is sensitive to soil moisture (W). Evapotranspiration (ET) reacts to soil moisture in a nonlinear way, f(W), as soils dry from saturation to wilt point. This nonlinear behavior and the fact that soil moisture varies on scales as small as 1–10 m in nature, while numerical general circulation …

Determining Total Emissions And Environmental Drivers Of Methane Flux In A Lake Erie Estuarine Marsh
Rey-Sanchez, A., Morin, T., Stefanik, K., Wrighton, K., Bohrer, G.

Estuarine freshwater marshes can act as an important ecosystem for carbon storage and flux because of its strategic position in a watershed. We monitored CH4and CO2 fluxes in Old Woman Creek, an estuarine wetland of Lake Erie, Ohio. The eddy covariance (EC) technique was used to measure fluxes of CH4 and CO2 continuously during the …

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 …
