Geochronologic date including bulk sediments thorium isotopes and authigenic beryllium isotopes data for a pelagic sediment core from northwestern Pacific Ocean are presented in this dataset. Moreover, Nd isotopic compositions of the authigenic Fe–Mn oxyhydroxide fractions extracted from pelagic sediments, together with the redox-sensitive metal proxies (e. g., Mn/Al and Mn/Ti ratios) and grain sizes of bulk sediments fron this sediment core are also included in this dataset.
