Sediments for the δ18O of planktic and benthic foraminifera analysis from core LV76-21 were sampled from 1 cm-thick slices with step of 2–5 cm along the core length. Foraminifera shells were picked from the sediment fractions of 150-250 µm in the samples where they were available. The δ18O of planktic and benthic foraminifera were measured at Tongji University (China) and at the Far Eastern Geological Institute (Russia). Isotope measurements from Tongji University were provided using a Finnigan‐MAT 252 mass spectrometer. The results were validated against a Chinese national carbonate standard (GBW04405) and NBS‐19. The standard deviation is 0.07‰ for δ18O. The isotope measurements from the Far Eastern Geological Institute were analyzed using a Finnigan-MAT 253 mass spectrometer with modification of Velivetskaya et al. (2009) without preliminary roasting. The standard deviation for the δ18O values is ± 0.05‰. All the values are reported on the Pee Dee Belemnite (PDB) scale. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.954778"!
