Ostracod Mg/Ca, Sr/Ca, Al/Ca and Fe/Ca ratios of <i>Sinocytheridea impressa</i> and <i>Neomonoceratina delicata</i>

Mg/Ca, Sr/Ca, Al/Ca and Fe/Ca ratios of marine shells of modern ostracods from Hong Kong and Japan surface sediments. Sediment samples were collected by the Environmental Protection Department (EPD), OCEAN-HK and Dr. Gengo Tanaka. Samples were measured through ICP-MS. The pictures of the ostracods used in this investigation can be found in HKU Data repository (https://doi.org/10.25442/hku.12886835.v1).
