Ocean warming and coastal eutrophication could intensify nitrous oxide emissions by bloom-forming green macroalgae.
Nitrous oxide (N₂O) is a potent and ozone-depleting greenhouse gas, for which the contribution of marine macroalgae to coastal N₂O dynamics remains poorly understood. Here, we investigated N₂O emissions from incubations with the bloom-forming green macroalga Ulva lactuca under simulated warming and eutrophication scena...
