Could changing ocean circulation have destabilized methane hydrate at the Paleocene/Eocene boundary?
During the Paleocene-Eocene Thermal Maximum (PETM, ~55 Ma), marine and terrestrial carbon isotope values exhibit a negative shift of at least 2.5‰, indicative of massive destabilization of marine methane hydrates, releasing ~1100 gigatonnes of methane carbon. The cause of the hydrate destabilization...
