Uncertainties in, and interpretation of, carbon flux estimates using the eddy covariance technique

Creator:: Loescher, H. W., Law, B. E., Mahrt, Larry, Hollinger, D. Y., Campbell, J., and Wofsy, S. C.
Abstract:: Whole ecosystem carbon dioxide (CO₂) exchange estimated with the eddy covariance (EC) technique has been central to studies on the responses of terrestrial ecosystems to disturbance and intra‐annual and interannual variations in climate, but challenges exist in understanding and reducing the uncertainty in estimates of net ecosystem exchange (NEE) of...

Size-dependent aerosol deposition velocities during BEARPEX'07

Creator:: Vong, R. J., Vong, I. J., Vickers, D., and Covert, D. S.
Abstract:: Aerosol concentrations and 3-D winds were measured from 9 to 25 September 2007, above a pine forest in California. The measurements were combined using the eddy covariance (EC) technique to determine aerosol eddy fluxes as a function of particle diameter within the accumulation mode size range (0.25 μm≤D[subscript]p≤1 μm here)....

Simulation of Water and Energy Fluxes in an Old-Growth Seasonal Temperate Rain Forest Using the Simultaneous Heat and Water (SHAW) Model

Creator:: Link, Timothy E., Flerchinger, Gerald N., Unsworth, Mike, and Marks, Danny
Abstract:: In the Pacific Northwest (PNW), concern about the impacts of climate and land cover change on water resources and flood-generating processes emphasizes the need for a mechanistic understanding of the interactions between forest canopies and hydrologic processes. Detailed measurements during the 1999 and 2000 hydrologic years were used to modify...

Inter-laboratory Validation of Bioaccessibility Testing for Metals

Creator:: Henderson, Rayetta G., Verougstraete, Violaine, Anderson, Kim, Arbildua, José J., Brock, Thomas O., Brouwers, Tony, Cappellini, Danielle, Delbeke, Katrien, Herting, Gunilla, Hixon, Greg, Odnevall Wallinder, Inger, Rodriguez, Patricio H., Van Assche, Frank, Wilrich, Peter, and Oller, Adriana R.
Abstract:: Bioelution assays are fast, simple alternatives to in vivo testing. In this study, the intra- and inter-laboratory variability in bioaccessibility data generated by bioelution tests were evaluated in synthetic fluids relevant to oral, inhalation, and dermal exposure. Using one defined protocol, five laboratories measured metal release from cobalt oxide, cobalt...

Comparing streambed light availability and canopy cover in streams with old-growth versus early-mature riparian forests in western Oregon

Creator:: Warren, Dana R., Keeton, William S., Bechtold, Heather A., and Rosi-Marshall, Emma J.
Abstract:: Light availability strongly influences stream primary production, water temperatures and resource availability at the base of stream food webs. In headwater streams, light is regulated primarily by the riparian forest, but few studies have evaluated the influence of riparian forest stand age and associated structural differences on light availability. In...

Analysis of the genome of leporid herpesvirus 4

Creator:: Babra, Bobby, Watson, Gregory, Xu, Wayne, Jeffrey, Brendan, Xu, Jia-Rong, Rockey, Dan, Rohrmann, George, and Jin, Ling
Abstract:: The genome of a herpesvirus highly pathogenic to rabbits, leporid herpesvirus 4 (LHV-4), was analyzed using high-throughput DNA sequencing technology and primer walking. The assembled DNA sequences were further verified by restriction endonuclease digestion and Southern blot analyses. The total length of the LHV-4 genome was determined to be about...

Leg 202 summary

Creator:: Mix, Alan C., Tiedemann, R., and Blum, P.
Abstract:: More than 7 km of long and relatively continuous sediment sequences from 11 sites in the southeast and equatorial Pacific were recovered during Leg 202 for the study of the Earth’s climate and biogeochemical systems on scales that range from tectonic (millions of years) to orbital (tens to hundreds of...

Development of a “smart” tracer for the assessment of microbiological activity and sediment-water interaction in natural waters: The resazurin-resorufin system

Creator:: Haggerty, Roy, Argerich, Alba, and Marti, Eugenia
Abstract:: A “smart” tracer is a tracer that provides, directly or through measurement of its concentration or in combination with another compound, at least one “bit” more of information about the environment through which it travels than a conservative tracer. In this study we propose and present the chemical compound resazurin...

Combined Effects of Wind-Driven Upwelling and Internal Tide on the Continental Shelf

Creator:: Kurapov, A. L., Allen, J. S., and Egbert, G. D.
Abstract:: Internal tides on the continental shelf can be intermittent as a result of changing hydrographic conditions associated with wind-driven upwelling. In turn, the internal tide can affect transports associated with upwelling. To study these processes, simulations in an idealized, alongshore uniform setup are performed utilizing the hydrostatic Regional Ocean Modeling...

Seasonal hydrology explains interannual and seasonal variation in carbon and water exchange in a semiarid mature ponderosa pine forest in central Oregon

Creator:: Thomas, Christoph, Law, Beverly E., Irvine, James, Martin, Jonathan, Pettijohn, J. Cory, and Davis, Kent J.
Abstract:: We analyzed 7 years (2002–2008) of micrometeorological and concurrent biological observations of carbon and water fluxes at a mature ponderosa pine forest in central Oregon in a semiarid climate. We sought to evaluate the extent that gross primary productivity, net ecosystem exchange, ecosystem respiration, net primary productivity, net ecosystem productivity,...
