| Outline of Final Research Achievements |
High latitude region including the Arctic has largest reservoir of soil organic carbon (SOC) in the Earth. Since the high latitude region would be significantly influenced with environmental change under global warming, fragile of soil carbon reservoir should be investigated. Thus we investigated here the carbon source of soil respiration to evaluate fragile characteristics of the SOC using natural level radiocarbon as a novel sensor of fragile soil organic matter under future global warming. Here Arctic soil were collected in a successional glacier foreland in Ny-Alesund, Svarvard islands, Norway. Microbial phospholipids fatty acids (PLFAs) were extracted from soils for compound-specific radiocarbon analysis. in the geological time scale. We discussed their results in the light of soil carbon dynamics under climate instability in the Arctic region.
