Cenozoic sea-level and cryospheric evolution from deep-sea geochemical and continental margin records
Using Pacific benthic foraminiferal δ18O and Mg/Ca records, we derive a Cenozoic (66 Ma)
global mean sea level (GMSL) estimate that records evolution from an ice-free Early Eocene …

[HTML][HTML] The Eocene–Oligocene transition: a review of marine and terrestrial proxy data, models and model–data comparisons
Abstract The Eocene–Oligocene transition (EOT) was a climate shift from a largely ice-free
greenhouse world to an icehouse climate, involving the first major glaciation of Antarctica …

Trends, rhythms, and aberrations in global climate 65 Ma to present
Since 65 million years ago (Ma), Earth's climate has undergone a significant and complex
evolution, the finer details of which are now coming to light through investigations of deep …

Cenozoic deep-sea temperatures and global ice volumes from Mg/Ca in benthic foraminiferal calcite
A deep-sea temperature record for the past 50 million years has been produced from the
magnesium/calcium ratio (Mg/Ca) in benthic foraminiferal calcite. The record is strikingly …

Marked decline in atmospheric carbon dioxide concentrations during the Paleogene
The relation between the partial pressure of atmospheric carbon dioxide (p CO2) and
Paleogene climate is poorly resolved. We used stable carbon isotopic values of di …

Rapid stepwise onset of Antarctic glaciation and deeper calcite compensation in the Pacific Ocean
The ocean depth at which the rate of calcium carbonate input from surface waters equals the
rate of dissolution is termed the calcite compensation depth. At present, this depth is∼ 4,500 …
