Today I presented my last findings on Nitrous Oxide ( #N2O) production by #Photochemodenitrification off the coast of West Greenland and in the Eastern Tropical South Pacific ( #ETSP) ocean

More cool results on this new process are coming soon!

Oxygen Isotope Fractionation of O2 Consumption through Abiotic Photochemical Singlet Oxygen Formation Pathways Oxygen isotope ratios of O2 are important tracers for assessing biological activity in biogeochemical processes in aquatic environments. In fact, changes in the 18O/16O and 17O/16O ratios of O2 have b...

Check out our new paper (in cooperation with @eawag.bsky.social and @unibas.ch) in @pubs.acs.org Environmental Au that highlights the importance of #photochemical #oxygen #consumption for assessing biological activity in sunlit surface waters.

Some bacteria and archaea make nitrous oxide during ammonia oxidation to nitrite in well-oxygenated waters, whereas denitrifying bacteria produce it during reduction of nitrate in oxygen-poor waters. None of these, however, could fully explain the observed increase. ‘It was just this weird conundrum that in many cases the mechanism that was being used to explain most of these emissions didn’t seem to be there,’ says Jennifer Glass at the Georgia Institute of Technology in Atlanta, US.

Scott Wankel of Woods Hole Oceanographic Institute in Massachusetts believes that the ‘exciting’ findings could solve a key mystery: ‘For a long time we’ve known that whatever nitrous oxide was getting out into the atmosphere was made in the upper [ocean] layer, and we thought that was nitrification by ammonia-oxidising bacteria and archaea – but they don’t like light,’ he says. ‘Here all you need is for the upper metre of seawater to have some organic matter in it, and the nitrous oxide will be quickly released to the atmosphere … it really could be driving the entire bus of the oceanic flux of nitrous oxide to the atmosphere, or at least a very large part of it.’

I am truly amazed by the reception our discovery has received in the scientific community 🥰🥰🥰
