Eocene-Oligocene sea surface temperature and pCO2 estimates

The long-term cooling trend of the Cenozoic is punctuated by shorter-term climatic events, such as the inception of permanent ice sheets on Antarctica at the Eocene-Oligocene Transition (~33.7 Ma). Taking advantage of the excellent state of preservation of coccolith calcite in equatorial Atlantic de...
