The occurrence of intervals of enhanced sequestration of organic matter (OM) during the Mid-Cretaceous-collectively termed "Oceanic Anoxic Events" (OAE)-reflect abrupt changes in global carbon cycling. These episodes raise questions about the causes for such perturbations, and their linkages to fluctuations in climate, marine biota, and ocean geochemistry preserved in the sedimentary record. Detailed assessment of the early Aptian event (OAE1a) in the Pacific has been precluded by the limited recovery of this stratigraphic interval, in...
