Journal ArticleDOI
Rapid stepwise onset of Antarctic glaciation and deeper calcite compensation in the Pacific Ocean
TL;DR: The changes in oxygen-isotope composition across the Eocene/Oligocene boundary are too large to be explained by Antarctic ice-sheet growth alone and must therefore also indicate contemporaneous global cooling and/or Northern Hemisphere glaciation.
Journal ArticleDOI
The Heartbeat of the Oligocene Climate System
Heiko Pälike,Richard D Norris,Jens O. Herrle,Jens O. Herrle,Paul A. Wilson,Helen K. Coxall,Caroline H Lear,Nicholas J Shackleton,Aradhna Tripati,Bridget S. Wade +9 more
TL;DR: A 13-million-year continuous record of Oligocene climate from the equatorial Pacific reveals a pronounced “heartbeat” in the global carbon cycle and periodicity of glaciations.
Journal ArticleDOI
Cooling and ice growth across the Eocene-Oligocene transition
TL;DR: The Eocene-Oligocene (E-O) climate transition as discussed by the authors marks a period of Antarctic ice growth and a major step from early Cenozoic greenhouse conditions toward today's glaciated climate state.
Journal ArticleDOI
Late Eocene to early Miocene ice sheet dynamics and the global carbon cycle
TL;DR: In this article, paired benthic foraminiferal trace metal and stable isotope records from equatorial Pacific Ocean Drilling Program Site 1218 were used to calculate seawater?18O (?w).
Journal ArticleDOI

TL;DR: In this article, the dominant rocks are basalts with geochemical characteristics distinct from those of mid-ocean ridge basalts and the presence of wood fragments, charcoal, pollen, spores and seeds in the shallow water sediments overlying the igneous basement show that the growth rate of the plateau was sufficient to form subaerial landmasses.
