This journal article (published in the Journal of Geodynamics) proposes that large amounts of carbon were liberated from submarine methane clathrate deposits during the mid-Cretaceous superplume event. Evidence for this hypothes is based on carbon isotope records of marine carbonates, marine organisms, and terrestrial plants. The author speculates that possible effects of this disruption on the global carbon cycle may have included widespread oceanic anoxia and changes in land plants at mid- to high-latitudes.
