Oxygen and carbon isotope stratigraphy for the Quaternary of Hole 502B: evidence for two modes of isotopic variability.

Abstract

The oxygen and carbon isotopic record of G. sacculifer in DSDP Holes 502 and 502B shows that the Quaternary interval is almost complete. Two modes of delta18O variation reflect the changing ice budget on the continents and imply different envelopes of sea level variation during the early and late Quaternary. The division is at about 900 ka BP. -after Author
