Warm tropical ocean surface and global anoxia during the mid-Cretaceous period
The middle of the Cretaceous period (about 120 to 80 Myr ago) was a time of unusually warm polar temperatures, repeated reef-drowning in the tropics and a series of oceanic anoxic events (OAEs) thatExpand

An alternative suggestion for the Pliocene onset of major northern hemisphere glaciation based on the geochemical provenance of North Atlantic Ocean ice-rafted debris
Abstract The onset of abundant ice-rafted debris (IRD) deposition in the Nordic Seas and subpolar North Atlantic Ocean 2.72 millions of years ago (Ma) is thought to record the Pliocene onset of majorExpand

Early Oligocene glaciation and productivity in the eastern equatorial Pacific: Insights into global carbon cycling
The onset of sustained Antarctic glaciation across the Eocene-Oligocene transition (EOT) marks a pivotal change in Earth's climate, but our understanding of this event, particularly the role of theExpand

Stable organic carbon isotope stratigraphy across Oceanic Anoxic Event 2 of Demerara Rise, western tropical Atlantic
Ocean Drilling Program (ODP) Leg 207 recovered expanded sections of organic-carbon-rich laminated shales on Demerara Rise (western tropical Atlantic). High-resolution organic carbon isotope and totalExpand

Sea-level and salinity fluctuations during the Paleocene–Eocene thermal maximum in Arctic Spitsbergen
Palaeoenvironmental manifestations of the Palaeocene-Eocene thermal maximum (PETM; ~56 Ma) are relatively well documented in low- to mid-latitude settings and at high southern latitudes, but noExpand

New biostratigraphic, magnetostratigraphic and isotopic insights into the Middle Eocene Climatic Optimum in low latitudes.
The Middle Eocene Climatic Optimum (MECO) was a warming event that interrupted the long-term Eocene cooling trend. While this event is well documented at high southern and mid-latitudes, it is poorlyExpand

Symbiont 'bleaching' in planktic foraminifera during the Middle Eocene Climatic Optimum
Many genera of modern planktic foraminifera are adapted to nutrient-poor (oligotrophic) surface waters by hosting photosynthetic symbionts, but it is unknown how they will respond to future changesExpand

Early Maastrichtian carbon cycle perturbation and cooling event: Implications from the South Atlantic Ocean
Published stable isotope records in marine carbonate are characterized by a positive ?18O excursion associated with a negative ?13C shift during the early Maastrichtian. However, the cause and evenExpand

A low threshold for North Atlantic ice rafting from "low-slung slippery" late Pliocene ice sheets
[1] Suborbital variability in late Pleistocene records of ice-rafted debris and sea surface temperature in the North Atlantic Ocean appears most extreme during times of enlarged ice sheets with aExpand

Causes of ice age intensification across the Mid-Pleistocene Transition
Significance Conflicting sets of hypotheses highlight either the role of ice sheets or atmospheric carbon dioxide (CO2) in causing the increase in duration and severity of ice age cycles ∼1 MyaExpand
