Rapid Acidification of the Ocean During the Paleocene-Eocene Thermal Maximum
The Paleocene-Eocene thermal maximum (PETM) has been attributed to the rapid release of ∼2000 × 109 metric tons of carbon in the form of methane. In theory, oxidation and ocean absorption of thisExpand
Astronomical pacing of late Palaeocene to early Eocene global warming events
At the boundary between the Palaeocene and Eocene epochs, about 55 million years ago, the Earth experienced a strong global warming event, the Palaeocene–Eocene thermal maximum. The leadingExpand
Subtropical Arctic Ocean temperatures during the Palaeocene/Eocene thermal maximum
The Palaeocene/Eocene thermal maximum, ∼55 million years ago, was a brief period of widespread, extreme climatic warming, that was associated with massive atmospheric greenhouse gas input. AlthoughExpand
Timing and nature of the deepening of the Tasmanian Gateway
[1] Tectonic changes that produced a deep Tasmanian Gateway between Australia and Antarctica are widely invoked as the major mechanism for Antarctic cryosphere growth and Antarctic CircumpolarExpand
The Geological Record of Ocean Acidification
Acid History As human activity continues to pump nearly 50-fold more CO2 into the atmosphere than any existing natural sources, the oceans absorb it. Over time, this vast quantity of excess oceanicExpand
Arctic hydrology during global warming at the Palaeocene/Eocene thermal maximum
This corrects the article DOI: 10.1038/nature05043
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 warmer subtropicalExpand
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. HereExpand
Warm arctic continents during the Palaeocene–Eocene thermal maximum
The Palaeocene–Eocene Thermal Maximum (PETM; ∼55.5 Ma) is a geologically relatively brief episode of extreme warmth. Both deep and surface ocean temperatures increased by up to 5 °C in equatorialExpand
From greenhouse to icehouse; organic-walled dinoflagellate cysts as paleoenvironmental indicators in the Paleogene
Abstract Dinoflagellates are an important component of the extant eukaryotic plankton. Their organic-walled, hypnozygotic cysts (dinocysts) provide a rich, albeit incomplete, history of the group inExpand
