Short summary
We present an open-access compilation of mineralogical and geochemical provenance data for surface sediments across the Arctic Ocean. The Circum-Arctic Sediment PROvenance Database (CASPROD) integrates four provenance proxies, including bulk sediment Sr–Nd isotopes, detrital zircon U–Pb ages, clay mineral assemblages, and detrital mineral compositions, from more than 4000 stations in the Arctic Ocean. All datasets are standardized with consistent metadata and are provided in multiple machine-readable formats.
