Marked Decline in Atmospheric Carbon Dioxide Concentrations During the Paleogene
The relation between the partial pressure of atmospheric carbon dioxide (pCO2) and Paleogene climate is poorly resolved. We used stable carbon isotopic values of di-unsaturated alkenones extracted… Expand
Significant Southern Ocean warming event in the late middle Eocene
A prominent middle Eocene warming event is identified in Southern Ocean deep-sea cores, indicating that long-term cooling through the middle and late Eocene was not monotonic. At sites on Maud Rise… Expand
Warming the fuel for the fire: Evidence for the thermal dissociation of methane hydrate during the Paleocene-Eocene thermal maximum
Dramatic warming and upheaval of the carbon system at the end of the Paleocene Epoch have been linked to massive dissociation of sedimentary methane hydrate. However, testing the Paleocene-Eocene… Expand
A Transient Rise in Tropical Sea Surface Temperature During the Paleocene-Eocene Thermal Maximum
The Paleocene-Eocene Thermal Maximum (PETM) has been attributed to a rapid rise in greenhouse gas levels. If so, warming should have occurred at all latitudes, although amplified toward the poles.… Expand
Coupled Greenhouse Warming and Deep Sea Acidification in the Middle Eocene
[1] The Middle Eocene Climatic Optimum (MECO) is an enigmatic warming event that represents an abrupt reversal in long-term cooling through the Eocene. In order to further assess the timing and… Expand
A 40-million-year history of atmospheric CO2
The alkenone–pCO2 methodology has been used to reconstruct the partial pressure of ancient atmospheric carbon dioxide (pCO2) for the past 45 million years of Earth's history (Middle Eocene to… Expand
Extreme warming of mid-latitude coastal ocean during the Paleocene-Eocene Thermal Maximum: Inferences from TEX86 and isotope data
Changes in sea surface temperature (SST) during the Paleocene-Eocene Thermal Max- imum (PETM) have been estimated primarily from oxygen isotope and Mg/Ca records generated from deep-sea cores. Here… Expand
The Role of Carbon Dioxide During the Onset of Antarctic Glaciation
Antarctica glaciation began soon after a large decrease in the concentration of atmospheric carbon dioxide around 35 million years ago. Earth’s modern climate, characterized by polar ice sheets and… Expand
The Palaeocene–Eocene carbon isotope excursion: constraints from individual shell planktonic foraminifer records
The Palaeocene–Eocene thermal maximum (PETM) is characterized by a global negative carbon isotope excursion (CIE) and widespread dissolution of seafloor carbonate sediments. The latter feature… Expand
Pliocene summer sea surface temperature reconstruction using silicoflagellates from Southern Ocean ODP Site 1165
[1] In the modern marine environment the silicoflagellate genus Dictyocha is rare, or absent, south of the Antarctic polar front (APF); the genus Distephanus, in contrast, is dominant. In sediments… Expand
