Late Pleistocene equatorial Pacific sediments can be correlated by the ratios of certain solution-susceptible versus solution-resistant planktonic foraminifera. These ratios fluctuate in a cyclic manner whose timing is in phase with glacial-interglacial fluctuations established by oxygen isotope geo-chronology. Glacial stages are characterized by less solution of foraminifera than interglacial stages.
