Fig. 1From: Sea surface temperature proxies (alkenones, foraminiferal Mg/Ca, and planktonic foraminiferal assemblage) and their implications in the Okinawa TroughBathymetric map of the OT. Circles indicate the locations of sediment cores, and triangles indicate the locations of time-series sediment traps. Dashed lines indicate the boundary dividing the OT into three regions (northern, middle, and southern). Original references for the indicated cores are given in Table 1 Back to article page
