Summary

Northern high latitudes contain large amounts of soil organic carbon (SOC), of which Alaskan terrestrial ecosystems account for a substantial proportion. In this study, the SOC accumulation in Alaskan terrestrial ecosystems over the last 15 000 years was simulated using a process-based biogeochemistry model for both peatland and non-peatland ecosystems. Comparable with the previous estimates of 25-70 PgC in peatland and 13-22 Pg C in non-peatland soils within 1m depth in Alaska using peat-core data, our model estimated a total SOC of 36-63 Pg C at present, including 27-48 PgC in peatland soils and 9-15 Pg C in non-peatland soils. Current vegetation stored 2.5-3.7 Pg C in Alaska, with 0.3-0.6 PgC in peatlands and 2.2-3.1 Pg C in non-peatlands. [...]
