Abstract:
Planktonic foraminiferal oxygen isotopes (δ¹⁸O), UK'37 and UK'37-derived SST of sediment core GIK18252-3 from the South China Sea (SCS). Planktonic foraminiferal δ18O values (versus Pee Dee belemnite standard) were determined on 20 - 25 specimens of G. ruber (white) sensu stricto (size fraction 250-400µm) at the Leibniz Laboratory at the University of Kiel. Sample preparation and UK'37 measurements were done at the Leibniz Laboratory at the University of Kiel. UKʹ37 was converted to temperature using the temperature calibration of Pelejero and Grimalt (1997; https://doi.org/10.1016/S0016-7037(97)00280-9). The record covers the past ~15.9 kyr.
