Description:
This study reconstructs the marine nitrogen cycle over 165 million years using isotopic records and Earth system modeling. The authors find remarkable long-term stability despite major climate and tectonic changes, suggesting strong feedbacks between biological productivity and ocean chemistry that maintained nitrogen availability, supporting life through Earth’s dynamic history.
