Globigerinoides ruber oxygen isotope data for the northern Bay of Bengal core MD12-3412

Globigerinoides ruber oxygen isotope data for the northern Bay of Bengal core MD12-3412. For all G. ruber analyses from core MD12-3412, 15 tests of G. ruber (sensu stricto) were picked from the 250-315 μm size fraction. New and published isotopic analyses on G. ruber tests were conducted at the LSCE laboratory using an ISOPRIME mass spectrometer. Samples were calibrated to PDB values with a laboratory standard referenced to NBS19. The internal reproducibility, estimated from replicate analyses of the standard, was ±0.06 ‰ for δ18O (1σ).
Data between 0-1346 cm corrected depth was originally published in Fauquembergue et al., 2019 (https://doi.org/10.1016/j.margeo.2019.105965) and the remaining data are published in Srivastava et al., 2025 (under review).
