In the paper by Maavara et al. (2019), N2O emissions previously reported in the literature and synthesized in Table 1 were incorrectly reproduced. This includes estuarine N2O emissions from Law et al. (1992), Bange et al. (1996) and De Wilde and De Bie (2000)(also incorrectly reported in the review by Murray et al., 2015). The correct version is shown below.

Table 1. Literature survey of all published global estimates for N2O emissions for rivers, reservoirs and estuaries. The table provides the source of the N loads used for the calculations, its value (and under which form, i.e. Total N—TN, Total Dissolved N—TDN, or Dissolved Inorganic N—DIN), the N2O emission factor, the global N2O emissions and an estimate of the corresponding emission rate per surface area. The latter are calculated using published estimates of the surface areas of rivers (Downing et al., 2012), reservoirs (Lehner et al., 2011) and estuaries (Dürr et al., 2011)

  • a Based on four studies with 0.3% and 3% (N2O:N2) for DIN load of <10 and >10 kg N ha−1 year−1, respectively.
  • b Based on six studies made in Europe and North America.
  • c IPCC default EF5-r (0.25%) was used for low case and 2.5% was assumed as the high case based on Seitzinger and Kroeze (1998).
  • d Based on observations conducted for 72 headwater streams in North America with 0.25% observed for denitrification and 0.5% assumed for nitrification.
  • e Based on meta-analysis of global data with 169 observations covering a wide range of rivers.
  • f Based on mean flux density from 58 measurements, multiplied by reservoir surface area (GRanD, Lehner et al., 2011).
  • g IPCC default EF5-r (0.25%) was used for low case and 2.5% was assumed as the high case based on Seitzinger and Kroeze (1998).
  • h Based on mean flux density from 56 measurements, multiplied by estuarine and tidal surface areas (average of Dürr et al., 2011; Woodwell et al., 1973).

Subsequently, the range of cited literature values of global estuarine N2O emissions on page 484 was incorrect.
