In the deep, silled basins of the equatorial Atlantic Ocean, large changes have occurred in
the rates of carbonate production and dissolution, deep water residence time, and rates of …

At low latitude locations in the northern hemisphere, striking changes in the relative
abundances and diversity of the two dominant planktic foraminifera genera, Morozovella …

Cenozoic stable carbon (δ 13 C) and oxygen (δ 18 O) isotope ratios of deep-sea
foraminiferal calcite co-vary with the 405 kyr eccentricity cycle, suggesting a link between …

It is well known that the equilibration timescale for the isotopic ratios 13C/12C and 14C/12C
in the ocean mixed layer is on the order of a decade, 2 orders of magnitude slower than for …

The carbon isotope ratio (δ13C) of plant material is commonly used to reconstruct the
relative distribution of C3 and C4 plants in ancient ecosystems. However, such estimates …

To what extent are individual middle Miocene eccentricity‐scale benthic foraminiferal carbon
isotope maxima (the so‐called CM events) related to changes in marine export productivity …

The Palaeocene–Eocene thermal maximum (PETM) is characterized by a global negative
carbon isotope excursion (CIE) and widespread dissolution of seafloor carbonate …

The Paleocene-Eocene Thermal Maximum (PETM) is recognized by a major negative
carbon isotope (δ13C) excursion (CIE) signifying an injection of isotopically light carbon into …

One of the mechanisms proposed to explain the roughly 20 ppmv increase in atmospheric
CO2 concentration from the early to late Holocene is a warming of the ocean surface that …

Over the past three million years, Earth's climate oscillated between warmer interglacials
with reduced terrestrial ice volume and cooler glacials with expanded polar ice sheets …
