Impact of ENSO on Nitrous Oxide Emissions in the Eastern Tropical Pacific
Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.Abstract Nitrous oxide (N2O ${\mathrm{N}}_{2}\mathrm{O}$) is a powerful greenhouse gas, with the ocean contributing ∼4.2 Tg N y−1 to global N2O ${\mathrm{N}}_{2}\mathrm{O}$ emissions. The Eastern Tropical Pacific (ETP) is a hotspot of N2O ${\mathrm{N}}_{2}\mathrm{O}$ emissions due to high N2O ${\mathrm{N}}_{2}\mathrm{O}$ production under low‐oxygen ...
