Abstract The Paleocene‐Eocene Thermal Maximum was a rapid global warming event at~
56 Ma that is associated with a negative carbon isotope excursion (CIE) and was driven by a …

Quantifying atmospheric carbon dioxide (CO 2) concentration and carbon (C) cycling during
Earth's ancient greenhouse episodes is essential for accurately interpreting current global …

The Atlantic meridional overturning circulation (AMOC) is a major component of global
ocean circulation, globally distributing heat, salt, and nutrients, exerting a fundamental …

Para el presente trabajo de tesis se han seleccionado dos áreas de estudio ubicadas en las
Cuencas Neuquina y Austral respectivamente. La primera está localizada en los …

Much of our understanding of Earth's past climate comes from the measurement of oxygen
and carbon isotope variations in deep-sea benthic foraminifera. Yet, long intervals in …

Chapter 1 explores the relationship between the magnitude of the ETM-1 carbon isotope
excursion (CIE) and paleo water depth in order to provide greater constraints on the wide …

Con el objetivo de conocer como varía la composición geoquímica de las aguas con la
profundidad y que factores influyen en estos cambios, se realizaron estudios de tierras raras …

Anthropogenic activity is causing atmospheric carbon dioxide to increase at rates
unprecedented in the geological record. The resulting rise in annual average temperatures …

Abstract During the Eocene-Oligocene transition, Earth cooled significantly from a
greenhouse to an icehouse climate. Nannofossil assemblages from Southern Ocean sites …

The Cenozoic represents the transition from the greenhouse world of the Cretaceous to the
ice house world of today. Nonetheless, it was not a steady linear trend from an ice free world …
