PI: Paul R. Moorcroft
Project Title: "Past, present & future of terrestrial CO2 flux in North-Eastern Forests: the role of ecophysiological responses, land-use history & disturbance legacies".
"In order of importance, the three principal causes of interannual variability in carbon uptake during the period were, (i) summer-time precipitation anomalies, (ii) spring-time temperature anomalies, and (iii) fall temperature anomalies".

PI Title: "Long-term response by the carbon budget of a mid-latitude deciduous forest to ecological processes, climate variations, and air pollutants"

PI's: Ruth K. Varner, University of New Hampshire
Patrick M. Crill, Stockholm University
Project Title: "High Frequency Measurements of CO2 Efflux from Forest Soil"
"The differences in soil CO2 efflux between the wetland margin, midslope and upland chambers were most pronounced after day 200 in the late summer/early fall"
"Soil CO2 efflux reached a maximum later in the year than total ecosystem respiration measured at the eddy covariance flux tower".
