Aerosol Properties At A Midlatitude Northern Hemisphere Continental Site
Koloutsou-Vakakis, S., Carrico, C. M., Kus, P., Rood, M. J., Li, Z., Shrestha, R., Ogren, J. A., Chow, J. C., Watson, J. G.

Measurements of chemical, physical, and optical properties of ambient aerosol particles were obtained at Bondville, Illinois. This research was completed to increase the spatial and temporal resolution of measured aerosol. Results from measurements describe (1) the physical and chemical characteristics of the aerosol and (2) the …

Photosynthesis And Light-Use Efficiency By Plants In A Canadian Boreal Forest Ecosystem
Whitehead, D., Gower, S. T.
Measurements of the photosynthetic response to midsummer irradiance were made for 11 species representing the dominant trees, understory shrubs, herbaceous plants and moss species in an old black spruce (Picea mariana (Mill.) B.S.P.) boreal forest ecosystem. Maximum rates of photosynthesis per unit …

The Seasonal Water And Energy Exchange Above And Within A Boreal Aspen Forest
Blanken, P., Black, T., Neumann, H., den Hartog, G., Yang, P., Nesic, Z., Lee, X.

The seasonal water and energy exchange of a boreal aspen forest underlain by a hazelnut understory is described. Measurements of above-aspen latent and sensible heat, short-wave and net radiation, and photosynthetically active radiation are compared to those measured above the hazelnut understory. Understory radiation measurements …

Response Of Stomatal Conductance To Drought In Ponderosa Pine: Implications For Carbon And Ozone Uptake
Panek, J. A., Goldstein, A. H.
To gain insight into the limitations imposed by a typical Mediterranean-climate summer drought on the uptake of carbon and ozone in the ponderosa pine (Pinus ponderosa Dougl. ex Laws.) ecosystem, we compared diurnal trends in leaf physiology of young trees in a watered and a control plot …

Use Of A Simulation Model And Ecosystem Flux Data To Examine Carbon-Water Interactions In Ponderosa Pine
Williams, M., Law, B. E., Anthoni, P. M., Unsworth, M. H.
Drought stress plays an important role in determining both the structure and function of forest ecosystems, because of the close association between the carbon (C) and hydrological cycles. We used a detailed model of the soil–plant–atmosphere continuum to investigate the links between carbon uptake and …

Factors Controlling Long- And Short-Term Sequestration Of Atmospheric CO2 In A Mid-Latitude Forest
Barford, C. C., Wofsy, S. C., Goulden, M. L., Munger, J. W., Pyle, E. H., Urbanski, S. P., Hutyra, L., Saleska, S. R., Fitzjarrald, D., Moore, K.

Net uptake of carbon dioxide (CO2) measured by eddy covariance in a 60- to 80-year-old forest averaged 2.0 ± 0.4 megagrams of carbon per hectare per year during 1993 to 2000, with interannual variations exceeding 50%. Biometry indicated storage of 1.6 ± 0.4 megagrams of carbon per hectare per year over 8 years, 60% in …

Groundwater Flow Patterns In A Large Peatland
Fraser, C., Roulet, N., Lafleur, M.

Groundwater flow patterns and geochemistry were studied in the Mer Bleue bog, near Ottawa, Ontario, Canada. Groundwater flow patterns alternated between recharge, i.e. head gradients producing flow from the surface of the peatland to the deeper peat, and discharge, i.e. head gradients indicating flow from the deeper peat …
