 Zusammenfassung: Permafrost landscapes in northern high latitudes with their massive organic carbon stocks are an important, poorly known, component of the global carbon cycle. However, in light of future Arctic warming, the sustainability of these carbon pools is uncertain. To a large part, this is due to a limited understanding of the carbon cycle processes because of sparse observations in Arctic permafrost ecosystems. Here, we present an eddy covariance dataset covering more than three years of continuous CO2 and CH4 flux observations within a moist tussock tundra ecosystem near Chersky in North-eastern Siberia. Through parallel observations of a disturbed (drained) area and a control area nearby, we aim to evaluate the long-term effects of a persistently lowered water table on the net vertical carbon exchange budgets and the dominating biogeochemical mechanisms. Persistently drier soils trigger systematic shifts in the tundra ecosystem carbon cycle patterns. Both, uptake rates of CO2 and emissions of CH4 decreased. Year-round measurements emphasize the importance of the non-growing season – in particular the “zero-curtain” period in the fall – to the annual budget. Approximately 60% of the CO2 uptake in the growing-season is lost during the cold-seasons, while CH4 emissions during the non-growing season account for 30% of the annual budget. Year-to-year variability in temperature conditions during the late growing season were identified as the primary control of the interannual variability observed in the CO2 and CH4 fluxes.
