Fig. 3: Global distribution of N2O flux (kg N-N2O ha−1 yr−1) in the ocean.
From: Global mapping of flux and microbial sources for oceanic N2O

The global oceanic N2O flux is 2.9 Tg N2O-N/yr, which was calculated by AOA-produced N2O flux and its proportion to total amount in each grid (N2OAOA/fAOA). Source data are provided as a Source Data file.
