The PAGES CoralHydro2k Seawater δ18O Database Project is a community-led effort to develop a new metadata-rich database for seawater oxygen isotope data consistent with Findability, Accessibility, Interoperability, and Reusability (FAIR) standards for digital assets. Our aim is to recover as many “hidden” seawater oxygen isotope datasets as possible from the global ocean, combine them with data in public databases and data repositories, and standardize the metadata. The project began in 2021 in recognition of the broad value of δ18Osw data in the Earth Sciences and the need for an updated database of δ18Osw data.  


We have established a Seawater Oxygen Isotope community page at the NSF EarthChem Library ( where δ18Osw data can be submitted, archived, and publicly accessed, and researchers can receive a unique digital object identifier (DOI) for their datasets. 

Final products

The new, machine-readable, and metadata-rich seawater δ18O database will be publicly available to the Earth science community (expected Aug 2023). The final database will also be hosted at the NOAA/World Data Service for Paleoclimatology (
