Spatial Variation In Regional CO2 Exchange For The Kuparuk River Basin, Alaska Over The Summer Growing Season
Vourlitis, G. L., Verfaillie, J., Oechel, W. C., Hope, A., Stow, D., Engstrom, R.

The spatial and temporal patterns in CO2 flux for the Kuparuk River Basin, a 9200-km2 watershed located in NE Alaska were estimated using the Regional …

Eddy Covariance Measurements Of CO2 And Energy Fluxes Of An Alaskan Tussock Tundra Ecosystem
Vourlitis, G. L., Oechel, W. C.

Eddy covariance was used to measure the net CO2 exchange and energy balance of a moist-tussock tundra ecosystem at Happy Valley, Alaska (69°08.54′ N, 148°50.47′ W), during the 1994–1995 growing seasons (June–August). The system operated for 75–95% of the time, and energy balance closure was within 5%, indicating …

Characteristics Of Energy And Water Budgets Over Wet Sedge And Tussock Tundra Ecosystems At North Slope In Alaska
Harazono, Y., Yoshimoto, M., Mano, M., Vourlitis, G. L., Oechel, W. C.

Energy budgets were measured at Arctic tundra ecosystems in Alaska, USA. Measurements were carried out over coastal tundra at Prudhoe Bay in 1994, and at wet sedge, moist and dry tussock tundra around Happy Valley in 1995. Sensible heat flux, H, and latent heat flux, lE, were determined by an eddy correlation technique.

Intercomparison Among Chamber, Tower, And Aircraft Net CO2 And Energy Fluxes Measured During The Arctic System Science Land-Atmosphere-Ice Interactions (ARCSS-LAII) Flux Study
Oechel, W. C., Vourlitis, G. L., Brooks, S., Crawford, T. L., Dumas, E.

Measurements of net ecosystem CO2 exchange (NEE) and energy balance were made using chamber-, tower-, and aircraft-based measurement techniques in Alaskan arctic tundra ecosystems during the 1994–1995 …

Cold Season CO2 Emission From Arctic Soils
Oechel, W. C., Vourlitis, G., Hastings, S. J.

Recent evidence indicates that significant amounts of C may be lost as CO2 to the atmosphere from tundra ecosystems during the fall, winter and spring months. Because high latitude ecosystems are …
