Throughout Earth's history, CO2 is thought to have exerted a fundamental control on
environmental change. Here we review and revise CO2 reconstructions from boron isotopes …

Stable isotope applications have evolved from simple characterizations of isotope
composition in organisms and organic matter, to highly complex methodologies on scales …

The early Eocene (56 to 48 million years ago) is inferred to have been the most recent time
that Earth's atmospheric CO 2 concentrations exceeded 1000 ppm. Global mean …

We explore a novel approach towards quantification of paleo-ecological signals from non-
analogue microfossil assemblages by quantifying relations between assemblages and high …

The carbon isotopic composition of organic matter preserved in marine sediments provides
a window into the global carbon cycle through geologic time, including variations in …

One of the great challenges in biogeochemical research over the past half a century has
been to quantify and understand the mechanisms underlying stable carbon isotope …

A negative carbon isotope excursion recorded in terrestrial and marine archives reflects
massive carbon emissions into the exogenic carbon reservoir during the Paleocene-Eocene …

New palynological, sedimentological, and geochemical records spanning the Middle
Eocene Climatic Optimum (MECO; ca. 40 Ma) in the equatorial Atlantic Ocean indicate that …

Paleoceanographic reconstructions are usually based on the chemical composition of
foraminiferal tests, and pristine calcite preservation is crucial to support reliable …

Abstract The Paleocene/Eocene Thermal Maximum (PETM) is characterized by pronounced
global warming and associated environmental changes. In the more-or-less two decades …
