The dataset includes five parts: Core data, Ventilation age, C. wuellerstorfi δ¹⁸O, C.suellerstorfi δ¹³C, and Sea water δ¹⁸O. For δ¹⁸O and δ¹³C analysis, 3-5 specimens of the epifaunal benthic foraminifera <i>C. wuellerstorfi</i> were selected from the &gt;150 µm fraction. All results are referenced against the PeeDee belemnite (PDB) and further calibrated using the National Bureau of Standards (NBS) 19. The analytical standard deviation stands at approximately ± 0.07 ‰. For AMS¹⁴C dating, 7–10 mg of well-preserved specimens of the planktic foraminifera <i>N. pachyderma</i> and 3–4 mg of the epifaunal benthic foraminifera <i>C. wuellerstorfi</i> were selected from the &gt;150 μm fraction at core depths of 0–1 and 3–4 cm. The ¹⁴C-ventilation age has been outlined as the conventional ¹⁴C disparity observed between benthic and planktic foraminifera. The bottom seawater δ¹⁸O (δ¹⁸O_sw), expressed in permil relative to Standard Mean Ocean Water (SMOW), was computed from the equilibrium δ¹⁸O of <i>C. wuellerstorfi</i>.
