Sea-surface temperature records based on planktic foraminiferal Mg/Ca (red) and alkenones in the central Okinawa Trough: Core A7 (Sun et al. 2005) and Core DGKS9604 (Yu et al. 2009); and the northern Okinawa Trough: Core KY07-04 PC01 (Kubota et al. 2010, 2015b) and Core MD98-2195 (Ijiri et al. 2005) as well as residual δ18O as a salinity proxy in Core KY07-04 PC01(Kubota et al. 2010, 2015a, b). SST and residual δ18O at Core KY07-04 PC01 and the errors (± 1σ) were derived by Paleo-Seawater Uncertainty Solver (PSU Solver) (Thirumalai et al. 2016) with the methodology of Kubota et al. (2019). Downcore profiles of relative abundances (%) of warm diatom indicators and Thalassionema variety index in Core KY07-04 PC01 were also shown. Gray hatches indicate MWP-A and YD periods. Horizontal broken lines denote pronounced decreases in warm diatom indicators during Holocene
