Exploring the impact of Cenomanian paleogeography and marinegateways on oceanic oxygen

Abstract

Cenomanian paleogeography has preconditioned the ocean on the runup to the Oceanic Anoxic Event 2 (OAE2) by controlling bottom water oxygen • A deep connection between the Pacific and Central Atlantic oceans is needed before OAE2 to explain the Central Atlantic redox data • The reconstructed Cenomanian oceanic circulation is vigorous but does not prevent significant parts of the ocean to be anoxic
