Geosciences Column: Don’t blame bacteria – nitrous oxide production in the ocean

In this month’s Geosciences Column, Celso Gomes highlights a recent result published in EGU’s Biogeosciences on the role of a particular single-celled microorganism in the production of nitrous oxide in the ocean. About 30% of atmospheric nitrous oxide (N2O), a greenhouse gas, is a product of the ocean. Therefore, by studying the mechanisms behind the oceanic production of this gas, sc ...[Read More]
