The geological record encodes the relationship between climate and atmospheric carbon
dioxide (CO2) over long and short timescales, as well as potential drivers of evolutionary …

Abstract Changes in terrigenous organic matter (OM) input, productivity and the associated
bottom-water redox conditions, together with forcing mechanisms and global carbon cycle …

Ocean acidification is expected to negatively impact calcifying organisms, yet we lack
understanding of their acclimation potential in the natural environment. Here we measured …

The B/Ca ratio of planktic foraminiferal calcite, a proxy for the surface ocean carbonate
system, displays large negative excursions during the Paleocene‐Eocene Thermal …

The ratio of boron to calcium (B/Ca) in marine biogenic carbonates has been proposed as a
proxy for properties of seawater carbonate chemistry. Applying this proxy to planktic …

Arguably among the most globally impactful climate changes in Earth's past million years
are the glacial terminations that punctuated the Pleistocene epoch. With the acquisition and …

The trace element and isotopic composition of foraminifera shells are widely used in
paleoceanography to reconstruct past ocean conditions. Individual foraminifer analysis (IFA) …

Abstract The Cenozoic Era has been characterized by large perturbations to the oceanic
carbon cycle and global climatic changes, but quantifying the magnitude and cause of these …

Abstract The Mg/Ca of planktic foraminifera is commonly assumed to be a univariate function
of ocean temperature, but recent work suggests that nonthermal variables may have a …

Reconstruction of the marine inorganic carbon system relies on proxy signal carriers, such
as element/calcium (El/Ca) ratios in foraminiferal shells. Concentrations of boron, lithium …
