Holocene sea-surface temperature, stratification and oxygenation datasets from core SK240/496 in the northeastern Arabian Sea

This data file contains proxy records and derived datasets generated for Saravanan et al. (2026), including the following: 1) Globigerinoides ruber δ¹⁸O, Mg/Ca-derived SST, and calculated seawater δ18O from core SK240/496; 2) individual foraminiferal δ18O data for G. ruber and Trilobatus sacculifer; 3) regional Arabian Sea SST stack and PC1 scores based on proxy records and LGMR reanalysis data; 4) mixed-layer species percentages; and 5) Arabian Sea mean z-scores of dysoxic species.
