Midlatitude Southern Hemisphere Temperature Change at the End of the Eocene Greenhouse Shortly Before Dawn of the Oligocene Icehouse

Haiblen, Anna; Opdyke, Bradley; Roberts, Andrew P.; Heslop, David; Wilson, Paul A.


The Eocene‐Oligocene transition (EOT) marked the initiation of large‐scale Antarcticglaciation. This fundamental change in Cenozoic climate state is recorded in deep‐sea sediments by arapid benthic foraminiferalδ18O increase and appearance of ice‐rafted debris in the Southern Ocean.However, we know little about the magnitude of cooling associated with the EOT in shallow waterenvironments, particularly at middle to high latitudes. Here we present new stratigraphic records of theC13r/C13n...[Show more]
