Figure F6. Comparison between tropical east and west Pacific sea-surface temperatures (SSTs) for the time interval 4.2–2.4 Ma. East Pacific SSTs are Mg/Ca SSTs from Site 1241. West Pacific SSTs are results from planktonic foraminiferal transfer functions, Modern Analog Technique (MAT), from Andersson (1997) for Ontong Java Plateau Site 806 (0°19´N, 159°21´E). * = modern SST values at the paleolocation of Site 1241.
