Short summary
The origin of stream dissolved organic matter (DOM) in a lowland headwater catchment was investigated using high-frequency sampling combined with chemical biomarker analysis. Inter-storm stream DOM corresponds to the flushing of soil DOM reservoirs, while storm stream DOM would also result from three additional mechanisms: biofilm destabilization, surface and sub-surface erosion.
