Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

At the Earth's surface, calcium (Ca) is a critical element at a variety of scales: it is soluble in
natural waters, a biological nutrient, and a major constituent of the dominant mineral sink for …

Abstract The Ocean Anoxic Event 2 (OAE2) about 93.5 million years ago was marked by
high atmospheric CO2 concentration, rapid global warming and marine anoxia and euxinia …

Ocean acidification triggered by Siberian Trap volcanism was a possible kill mechanism for
the Permo-Triassic Boundary mass extinction, but direct evidence for an acidification event …

The engineered removal of atmospheric CO2 is now considered a key component of
mitigating climate warming below 1.5° C. Mineral carbonation is a potential negative …

Abstract The Paleocene-Eocene Thermal Maximum (PETM) hyperthermal,~ 56 million years
ago (Ma), is the most dramatic example of abrupt Cenozoic global warming. During the …

High-resolution osmium (Os) isotope stratigraphy across the Cenomanian–Turonian
Boundary Interval from 6 sections for four transcontinental settings has produced a record of …

Mercury (Hg) is increasingly being used as a sedimentary tracer of Large Igneous Province
(LIP) volcanism, and supports hypotheses of a coincidence between the formation of several …

Abstract Oceanic Anoxic Event 2 (Cenomanian–Turonian: ca 94 Ma) represents a major
palaeoceanographic phenomenon that took place during an interval of extreme global …

There is an abundance of evidence for short intervals of cold climatic conditions during the
Early Cretaceous. However, the lack of a high-resolution, long-term Early Cretaceous …
