Carbon cycle model calculations have been conducted to test the idea that the entire ocean
became undersaturated or nearly undersaturated with respect to calcium carbonate at the …

Ocean acidification associated with emplacement of the Central Atlantic Magmatic Province
(CAMP) has been hypothesized as a kill mechanism for the end-Triassic mass extinction, but …

Palaeobotanical and geochemical evidence indicate a sudden rise in atmospheric carbon
dioxide (CO2) across the Triassic-Jurassic boundary, probably reflecting the combined effect …

The end‐Triassic mass extinction coincided with a negative δ13C excursion, consistent with
release of 13C‐depleted CO2 from the Central Atlantic Magmatic Province. However, the …

While demonstrating ocean acidification in the modern is relatively straightforward (measure
increase in atmospheric CO2 and corresponding ocean chemistry change), identifying …

This study investigates whether the end-Triassic biotic crisis was coupled with a perturbation
of the marine C-isotope budget. The marine C-isotope signature serves as a proxy of the …

In the aftermath of the Cretaceous/Tertiary (K/T) boundary event (∼ 65 my ago), pelagic
carbonate productivity was greatly reduced for several hundred thousand years. A decrease …

We report the results of new stable oxygen and carbon isotope analyses on carbonate fine
fraction, whole rock, and benthic foraminifers, CaCO3 and coarse fraction percentage …

A compilation of new and published stratigraphic, paleontological and geochemical data is
used to detect the reciprocal influences of carbon cycling and global environmental changes …

The Phanerozoic has seen fundamental changes in the global biogeochemical cycling of
calcium carbonate (CaCO3), particularly the advent of biomineralization during the early …
