Stable carbon isotope ratios of planktonic foraminifera from ODP Hole 130-806B on the Ontong Java Plateau (Appendix) ...
We present delta13C records spanning the last 2 m.y. of two planktonic foraminiferal taxa (Globigerinoides sacculifer and Pulleniatina) from Ocean Drilling Program Site 806 on the Ontong Java Plateau, western equatorial Pacific. The sampling interval is between 4 and 5 k.y. The two taxa are thought...
