New sediment core reveals details about Cretaceous Oceanic Anoxic Event

Editor’s Highlight—


A newly-drilled sediment core in the Tarfaya Basin, Morocco, has captured an extraordinarily detailed sequence of the Cretaceous Oceanic Anoxic Event 2 (OAE2). This paper presents the results of combined carbon isotopic-micropaleontological-trace metal study on the core. The expanded sequence allowed the authors to measure these parameters at significantly finer time resolution than anyone previously. The detailed sampling and good age control of these data provide strong evidence of the links between astronomic forcings, oceanic paleocirculation, and paleoclimate.
