[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 …

Size sorting in marine muds: Processes, pitfalls, and prospects for paleoflow‐speed proxies
The basis for, and use of, fine grain size parameters for inference of paleoflow speeds is
reviewed here. The basis resides in data on deposited sediment taken in conjunction with …

Ocean overturning since the Late Cretaceous: Inferences from a new benthic foraminiferal isotope compilation
Benthic foraminiferal oxygen isotopic (δ18O) and carbon isotopic (δ13C) trends, constructed
from compilations of data series from multiple ocean sites, provide one of the primary means …

Gateway-driven weakening of ocean gyres leads to Southern Ocean cooling
Declining atmospheric CO2 concentrations are considered the primary driver for the

Early Palaeogene temperature evolution of the southwest Pacific Ocean
Relative to the present day, meridional temperature gradients in the Early Eocene age (∼
56–53 Myr ago) were unusually low, with slightly warmer equatorial regions but with much …

Onset of Antarctic Circumpolar Current 30 million years ago as Tasmanian Gateway aligned with westerlies
Earth's mightiest ocean current, the Antarctic Circumpolar Current (ACC), regulates the
exchange of heat and carbon between the ocean and the atmosphere, and influences …

Eocene cooling linked to early flow across the Tasmanian Gateway
The warmest global temperatures of the past 85 million years occurred during a prolonged
greenhouse episode known as the Early Eocene Climatic Optimum (52–50 Ma). The Early …

Descent toward the Icehouse: Eocene sea surface cooling inferred from GDGT distributions
The TEX86 proxy, based on the distribution of marine isoprenoidal glycerol dialkyl glycerol
tetraether lipids (GDGTs), is increasingly used to reconstruct sea surface temperature (SST) …

The enigma of Oligocene climate and global surface temperature evolution
Falling atmospheric CO2 levels led to cooling through the Eocene and the expansion of
Antarctic ice sheets close to their modern size near the beginning of the Oligocene, a period …

Heterogeneity in global vegetation and terrestrial climate change during the late Eocene to early Oligocene transition
Rapid global cooling at the Eocene–Oligocene Transition (EOT),~ 33.9–33.5 Ma, is widely
considered to mark the onset of the modern icehouse world. A large and rapid drop in …
