Short summary
This study presents a global database of nitrogen isotope data from ancient ocean sediments, covering Earth's history from the present back to billions of years ago. The database includes over 70 000 nitrogen isotope records from 417 studies, along with essential geological context and related chemical data. This database will help reveal the mechanisms behind critical events like mass extinctions and major ocean changes, enhancing our understanding of Earth's long-term environmental processes.
