Outline of Final Research Achievements

This study aims to clarify the emission and efflux processes of soil carbon in the High Arctic and to predict changes in the processes in a wide-scale by using an ecosystem carbon cycle model and remote sensing techniques. The area of major vegetation types in the study area (Brogger Peninsula, Svalbard) was quantified by analyzing a satellite image. Field studies were conducted mainly in peatlands for which data of carbon cycle were scarce. Apparent rates of C accumulation in a peatland, estimated based on the 14C age and amount of peat in the active layer, were calculated to be 9.0-19.2 gC m-2 yr-1. The measurements of CO2 fluxes and model analyses revealed that the peatland was an active place of carbon sequestration. The analysis of DOC in the stream water showed that a significant proportion of the fixed C was lost from the peatland. Based on these results, we evaluated the whole carbon dynamics in the study area and constructed a prediction model.
