definition: The effects of disturbance and climate on carbon storage and the exchanges of CO2, water vapor and energy exchange of evergreen coniferous forests in the Pacific Northwest: integration of eddy flux, plant and soil measurements at a cluster of supersites NACP Project Profile http://www.nacarbon.org/cgi-nacp/web/investigations/inv_pgp.pl?pgid=284 The goal is to continue investigating the effects of disturbance and interannual variation in climate on processes controlling carbon storage and the exchanges of energy, CO2, and water vapor in semi-arid and mesic coniferous forests at AmeriFlux sites in Oregon: the Metolius mature and young ponderosa pine sites (MP, YP), and the Marys River mature Douglas-fir site (MF). This is a cluster of supersites with measurements of ecosystem processes, eddy covariance, advection, and footprint modeling. Our objectives are to combine tower and ground-based observations at the semi-arid Metolius MP and YP to investigate effects of disturbance and interannual variation in climate on C storage and CO2 and water vapor exchange (disturbance gradient), and at the MF site for comparisons of response of mature semi-arid and mesic coniferous forests to seasonal and interannual variation in climate (climate gradient).
