This dissertation develops and applies coupled marine sulfur and strontium cycle modeling to the highly dynamic Early Cretaceous demonstrating the value of increased model constraint from linkage of biogeochemical cycles with shared forcing factors. A foundation for this work is first provided by review of relevant geochemical, sedimentological, and paleontological...
This dissertation researches the Cenomanian, Turonian, and Coniacian Stages (100.5 - 86.3 Ma) of the Cretaceous Period, a geologic interval of interest due to its extreme global warmth, iconic faunas, and oceanic anoxic events (OAEs). Five globally dispersed geochemical and stratigraphic case studies reconstruct interactions of the mid-Cretaceous carbon cycle...
