N1 - Funding Information:
The authors would like to thank Taipei City Middle School Student Scientific Research Scholar Program, Taipei First Girls High School Science Class, the chief scientists Luc Beaufort and Min-Te Chen of 2005 PECTEN cruise, Chun-Chih Yang and Hui-Yin Suk for foraminifera picking and analyses, and Taiwan Ocean Research Institute for providing sediment materials. Determination of Mg/Ca ratios were supported by grants from the Science Vanguard Research Program of the Ministry of Science and Technology (MOST) (110-2123-M-002-009 to C.-C.S.; 110-2636-M-002-011 to L.L.), the National Taiwan University ( 109L8926 to C.-C.S.; 109L892603 to L.L.), and the Higher Education Sprout Project of the Ministry of Education (110L901001 and 110L8907 to C.-C.S.; 110890704 to L.L.).

N2 - Here we present derived thermal-hydrological variations data during the Marine isotope stages (MISs) 10–12 using surface and subsurface dwelling planktonic foraminiferal geochemical proxies of a sedimentary core of MD05-2925 (9.3oS, 151.5oE, water depth 1661 m, core depth 1842–2430 cm), Solomon Sea. Globigerinoides ruber (s.s., white, 250–300 µm) and Pulleniatina obliquiloculata (355–425 µm) tests were hand-picked and cleaned for stable carbon and oxygen isotopes and Mg/Ca analyses. Composite benthic foraminifera tests (>250 µm, Uvigerina spp., and Bulimina spp.) are also hand-picked and cleaned for stable oxygen isotope stratigraphy. In total, 235 and 148 measurements for C-O stable isotopes and Mg/Ca ratios for planktonic foraminifera in 2–5 cm resolution for the period from 352.1 to 462.3 ka are presented in this data report, respectively. Age model is established by tuning composite benthic foraminiferal oxygen isotope to global composite benthic foraminifera oxygen isotope stack LR04. Surface and subsurface temperatures and seawater oxygen isotopes (δ18OW, without ice volume correction) were calculated.
