The PAGES CoralHydro2k Seawater δ18O Database Project is a community-led effort to develop a new, machine-readable, and 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 (e.g. from journal supplemental tables) as possible from the global ocean, collate datasets spread across different data repositories, and standardize the metadata. The project began in 2021 in recognition of the value of δ18Osw data to the broad Earth science community and the lack of a comprehensive database of δ18Osw data that is publicly available and actively maintained. 


A Seawater Oxygen Isotope community page is being established at the NSF EarthChem Library ( where δ18Osw data can be submitted, archived, and accessed via a unique digital object identifier (DOI). The database will also be hosted at the NOAA/World Data Service for Paleoclimatology (

Final products

A new, machine-readable, and metadata-rich seawater δ18O database will be publicly available to the Earth science community (expected Fall 2022).
