Clay and detrital minerals, Sr-Nd isotopes, and zircon U-Pb ages in Arctic Ocean surface sediments – Circum-Arctic Sediment PROvenance Database (CASPROD): A database of mineralogy and geochemistry for the Circum-Arctic surface sediments

Sr-Nd isotopes, clay mineral assemblages, detrital mineral compositions, and detrital zircon U-Pb ages provide complementary constraints on sediment provenance in the Arctic Ocean. This dataset integrates multi-proxy records from a broad spatial network, comprising 4309 stations, including bulk sediment Sr-Nd isotopes (n=175 stations), detrital zircon U-Pb ages (n=4671 grains from 21 key stations), clay mineral assemblages (n=1647 stations), and detrital mineral proportions (n=2465 stations). The spatial distribution map and plots of these data are presented in Yao et al. (2026), where a comprehensive interpretation is also provided.
