Short summary
The study examined dynamics of DOC export from a permafrost peatland catchment located in northeastern China. The findings indicated that the DOC export is a transport-limited process and the DOC load was significant for the net carbon balance in the studied catchment. The flowpath shift process is key to observed DOC concentration, resources and chemical characteristics in discharge. Permafrost degradation would likely elevate the proportion of microbe-originated DOC in baseflow.
