Five-years eddy-covariance measurements of CO2 fluxes in an Atlantic blanket bog in South-Western Ireland

摘要

In this paper we report the first estimates of five years CO2 flux measurements using an eddy covariance system in a pristine Atlantic blanket bog in Glencar,Co.Kerry,Ireland,between the 1~(st) October 2002 and the 30~(th) September 2007.Blanket bogs are peatlands that occur in maritime regions where precipitation is much greater than evapotranspiration.We found that the bog ecosystem was a CO2 sink for five months in each year.The annual CO2 flux had an average sink magnitude of 52 g C-CO2 m~(-2).The CO2 fluxes measured in the Glencar peatland are similar to those found in a boreal raised bog in southern Canada and in a fen in Southern Finland.
