Abstract

The Paleocene-Eocene thermal maximum (PETM) has been attributed to the rapid release of ∼2000 × 10 9 metric tons of carbon in the form of methane. In theory, oxidation and ocean absorption of this carbon should have lowered deep-sea pH, thereby triggering a rapid (<10,000-year) shoaling of the calci...
