Just published a paper with collaborators from the Ward lab on the pathways of N2O production by marine AOA! We used dual-isotope labeling to determine the mechanisms involved. Check it out in @PNASNews : pnas.org/doi/10.1073/pnas.22… #N2O #archaea @ICoN8_Princeton

Pathways of N2O production by marine ammonia-oxidizing archaea determined from dual-isotope...

The ocean is a net source of the greenhouse gas and ozone-depleting substance, nitrous oxide (N2O), to the atmosphere. Most of that N2O is produced...
