Benthic foraminiferal porosity, oxygen isotope, and bulk elements data of core TN041-8JPC

This study reconstructs BWO variations during this period from sediment core TN041-8JPC (17°48.76’N, 57°30.34’E, 761 m water depth) in the western Arabian Sea OMZ, utilizing proxies including benthic foraminiferal surface porosity, redox-sensitive trace metal enrichment factors (e.g., UEF), and U/Ba ratios.
