Toomey, M., Friedl, M. A., Frolking, S., Hufkens, K., Klosterman, S., Sonnentag, O., Baldocchi, D. D., Bernacchi, C. J., Biraud, S. C., Bohrer, G., Brzostek, E., Burns, S.

The proliferation of digital cameras co‐located with eddy covariance instrumentation provides new opportunities to better understand the relationship between canopy phenology and the seasonality of canopy photosynthesis. In this paper we analyze the abilities and limitations of canopy color metrics measured by digital repeat photography …

Does day and night sampling reduce spurious correlation between canopy photosynthesis and ecosystem respiration?
Dennis Baldocchi, Cove Sturtevant

It is necessary to partition eddy covariance measurements of carbon dioxide exchange into its offsetting gross fluxes, canopy photosynthesis, and ecosystem respiration, to understand the biophysical controls on the net fluxes. And independent estimates of canopy photosynthesis (G) and ecosystem respiration (R) are needed to validate …

Old-Growth CO2 Flux Measurements Reveal High Sensitivity To Climate Anomalies Across Seasonal, Annual And Decadal Time Scales
Wharton, S., Falk, M., Bible, K., Schroeder, M., Paw U, K.T.

The traditional hypothesis that old-growth forests are carbon neutral is under debate as recent studies
show evidence of net carbon sequestration. Here, we present a decade (1998–2008) of carbon dioxide,
water and energy fluxes from an old-growth stand in the American Pacific Northwest to identify
ecosystem-level responses to …

Stand-level gas-exchange responses to seasonal drought in very young versus old Douglas-fir forests of the Pacific Northwest
Wharton, S., Schroeder, M., Bible, K., Falk, M., Paw U, K.T.

This study examines how stand age affects ecosystem mass and energy exchange response to seasonal drought in three adjacent Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) forests. The sites include two early seral (ES) stands (0-15 years old) and an old-growth (OG) (~ 450-500 years old) forest in the Wind River Experiment Forest, …

Strong links between teleconnections and ecosystem exchange found at a Pacific Northwest old-growth forest from flux tower and MODIS EVI data
Wharton, S., Chasmer, L., Falk, M., Paw U, K.T.

Variability in three Pacific teleconnection patterns are examined to see if net carbon exchange at a low-elevation, old-growth forest is affected by climatic changes associated with these periodicities. Examined are the Pacific Decadal Oscillation (PDO), Pacific/North American Oscillation (PNA) and El Niño-Southern Oscillation …

Turbulence considerations for comparing ecosystem exchange over old-growth and clear-cut stands for limited fetch and complex canopy flow conditions
Wharton, S., Schroeder, M., Paw U, K.T., Falk, M., Bible, K.

Carbon dioxide, water vapor, and energy fluxes were measured using eddy covariance (EC) methodology over three adjacent evergreen forests in southern Washington State to identify stand-level age-effects on ecosystem exchange. The sites represent Douglas-fir forest ecosystems at two contrasting successional stages: old-growth (OG) …

Flux Partitioning In An Old-Growth Forest: Seasonal And Interannual Dynamics
Falk, M., Wharton, S., Schroeder, M., Ustin, S., U, K. T.

Turbulent fluxes of carbon, water and energy were measured at the Wind River Canopy Crane, Washington, USA from 1999 to 2004 with eddy-covariance instrumentation above (67 m) and below (2.5 m) the forest canopy. Here we present the decomposition of net ecosystem exchange of carbon (NEE) into gross primary …

Is soil respiration a major contributor to the carbon budget within a Pacific Northwest old-growth forest?
Falk, M., Paw U, K.T., Wharton, S., Schroeder, M.

Carbon dioxide (CO2) exchange was measured above the forest floor of a temperate Douglas-fir (Pseudotsuga menziesii (Mirbel)
Franco) and Western Hemlock (Tsuga heterophylla (Raf.) Sarg.) old-growth forest in southern Washington State. Continuous flux
measurements were conducted from July 1998 to December 2003 using the eddy-covariance …

Ecological Setting Of The Wind River Old-Growth Forest
Shaw, D., Franklin, J., Bible, K., Klopatek, J., Freeman, E., Greene, S., Parker, G.

The Wind River old-growth forest, in the southern Cascade Range of Washington State, is a cool (average annual temperature, 8.7°C), moist (average annual precipitation, 2223 mm), 500-year-old Douglas-fir–western hemlock forest of moderate to low productivity at 371-m elevation on a less than 10% slope. There is a seasonal snowpack …

Production, Respiration, And Overall Carbon Balance In An Old-Growth Pseudotsuga-Tsuga Forest Ecosystem
Harmon, M.E., Bible, K., Ryan, M.G., Shaw, D.C., Chen, H., Klopatek, J., Li, X.

Ground-based measurements of stores, growth, mortality, litterfall, respiration, and decomposition were conducted in an old-growth forest at Wind River Experimental Forest, Washington, USA. These measurements were used to estimate gross primary production (GPP) and net primary production (NPP); autotrophic respiration (R_a) …
