Indian Summer Monsoon runoff variability, foraminiferal biogeochemical changes, and radiocarbon ages since the Last Glacial Maximum from Site U1446, NW Bay of Bengal

This data file contains 1) radiocarbon ages on planktic foraminiferal shells, 2) planktic foraminiferal (Globigerinoides ruber) δ¹⁸O, δ¹³C, Mg/Ca, Cd/Ca, and U/Ca wrt CCSFD and our age model, 3) inverted SST, SSS, and seawater-δ¹⁸O based on paired Mg/Ca-δ¹⁸O measurements in G. ruber, 4) multispecies individual foraminiferal analyses δ¹⁸O and δ¹³C data for the late Holocene, early Holocene, and Heinrich Stadial 1 timeslices, and 5) relative abundances of Globorotalia species all generated at IODP Site U1446 situated in the Mahanadi Basin, northwest Bay of Bengal. These results have been presented in Thirumalai et al. 2025 (Nature Geoscience)
