Introduction The auxiliary material contains a text and and 9 figures. 1. 2010gl014202-txts01.pdf Text for Core material, foraminifer isotopes, and age controls; Mg/Ca SST determination; change of wind, ocean circulation and SST after the reduction or shutdown of THC in a coupled model; the simulated Kuroshio in the present coupled climate models. Figure S1: A map showing the location and regional topography of core MD012404 in the Okinawa Trough. The topography shows that the coring site is located in a small topographic low near the western edge of the OT. Figure S2: Benthic (top) and planktic (bottom) foraminifer delta_18O of core MD012404. The lines are five-point averaging from the original data points (shown in gray lines). The bars on the top indicate 19 AMS 14C dating and plain arrows indicate the isotope age control points that were used for developing the age model. Figure S3: 14C age (calibrated to calendar years) versus depth of core MD012404. Figure S4: MD012404 Mg/Ca SSTs measured in NTU (orange) and WHOI (blue). The left bottom panel shows the differences of the Mg/Ca SSTs measured from the two laboratories. Figure S5 The anomalies of sea surface wind field (black arrows) and wind speed (color shaded) between the water-hosing experiment and the control run. Figure S6: The anomalies of upper-100m current field (black arrows) and current speed (color shaded) between the water-hosing experiment and the control run. Though the increasing of current speed is usually less than 1cm/s in the Kuroshio region in water-hosing experiment, the ratio is considerable of about 10% comparing to the mean current speed of less than 10cm/s in the modeled Kuroshio (see Figure S8). Figure S7: The anomalies of SST (color shaded) between the water-hosing experiment and the control run. Figure S8 The simulated present upper-100m current field (black arrows) and current speed (color shaded) in the North Pacific in the FOAM model.Figure S9 The simulated present upper-100m current field (black arrows) and current speed (color shaded) in the North Pacific in the CM2.1 model.
