Revised late Pliocene composite section for ODP Site 138-846 T. D. Herbert, R. P. Caballero-Gill, and J. B. Novak https://doi.org/10.1594/PANGAEA.931478

Short summary

The Pliocene represents a geologically warm period with polar ice restricted to the Antarctic. Nevertheless, variability and ice volume persisted in the Pliocene. This work revisits a classic site on which much of our understanding of Pliocene paleoclimate variability is based and corrects errors in data sets related to ice volume and ocean surface temperature. In particular, it generates an improved representation of an enigmatic glacial episode in Pliocene times (circa 3.3 Ma).
