a Correlation between dissolved organic carbon (DOC) concentrations and N2O yields. Grey points denote samples affected by reservoirs, and were excluded from the correlation analysis. b Correlation between dissolved oxygen saturation (%O2) and ratios of (nirS + nirK)/nosZ. The red lines represent the fit of a linear regression through the observed data and the vertical dashed line denotes the boundary between super- and sub-saturated dissolved oxygen.
