Environmental precursors to rapid light carbon injection at the Palaeocene/Eocene boundary
The start of the Palaeocene/Eocene thermal maximum—a period of exceptional global
warming about 55 million years ago—is marked by a prominent negative carbon isotope …

Increased thermohaline stratification as a possible cause for an ocean anoxic event in the Cretaceous period
Ocean anoxic events were periods of high carbon burial that led to drawdown of
atmospheric carbon dioxide, lowering of bottom-water oxygen concentrations and, in many …

Evidence for upwelling of corrosive" acidified" water onto the continental shelf
The absorption of atmospheric carbon dioxide (CO2) into the ocean lowers the pH of the
waters. This so-called ocean acidification could have important consequences for marine …

Hot times for the Cretaceous Oceans
E Kintisch - 2006 - science.org
Ancient evidence from the sea floor suggests that the ocean surface some 90 million years
ago was hotter than the water in a hot tub—and that climate modelers are underestimating …

Rapid acidification of the ocean during the Paleocene-Eocene thermal maximum
The Paleocene-Eocene thermal maximum (PETM) has been attributed to the rapid release
of∼ 2000× 109 metric tons of carbon in the form of methane. In theory, oxidation and ocean …

Anthropogenic ocean acidification over the twenty-first century and its impact on calcifying organisms
Today's surface ocean is saturated with respect to calcium carbonate, but increasing
atmospheric carbon dioxide concentrations are reducing ocean pH and carbonate ion …

Massive expansion of marine archaea during a mid-Cretaceous oceanic anoxic event
Biogeochemical and stable carbon isotopic analysis of black-shale sequences deposited
during an Albian oceanic anoxic event (∼ 112 million years ago) indicate that up to 80 …
