- 1Rare molecules reveal how nitrogen vanishes from ecosystems●How do scientists measure nitrogen disappearing from an ecosystem? A new Science study co-authored by SETI Institute Sen
A new study in Science co-authored by SETI Institute Senior Research Scientist Dale Andersen shows that rare nitrogen molecules containing two heavy isotopes can directly measure biological nitrogen loss in ecosystems. The method lets scientists trace denitrification across lakes, aquifers, and coastal waters, offering a clearer picture of how nitrogen cycles through and leaves natural systems.
