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 71 000 nitrogen isotope records from 424 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.

Short summary
The Deep-Time Marine Sedimentary Element Database (DM-SED) expands upon the Sedimentary Geochemistry and Paleoenvironments Project (SGP) database, totalling 63 627 entries and covering major and trace elements and some stable isotopes in ancient marine sediments. This database is not only a significant reference for reconstructing Earth's system evolution but is also a valuable resource for studying palaeo-environments, palaeo-climates, and geochemical cycles.

Short summary
Building on the foundation of Palynodata, the Global Acritarch Database (GAD) added 29 new fields, 4531 new entries, 2 238 366 new metadata points, and 415 new references, resulting in a database comprising 115 860 entries, 43 fields, 3 050 852 metadata points, and 7791 references. GAD represents records from 1146 different sampling sites spanning geological history from the Precambrian to the Phanerozoic, and the fossil records include 1456 genera and 9865 species (excluding sp.).
