Stratigraphy-Earth History

Beginning in 1990 and continuing to the present the Sequence Stratigraphy group has been studying the rise and fall of sea level and its effects on sedimentation patterns on the Atlantic Margin. During this time we have drilled and analyzed coreholes on the New Jersey, Delaware, and Virginia coastal plains (ODP Legs 150X, and 174AX; ICDP-USGS Eyreville, Va corehole). We have also drilled coreholes on the modern middle continental shelf (IODP Expedition 313) and the modern outer continental shelf and slope (ODP Legs 150 and 174A). Our studies encompass unique views of major climate transitions in Earth history, specifically the Cretaceous/Paleogene mass extinction (K/Pg), the Paleocene/Eocene Thermal Maximum (PETM), Eocene hyperthermals, the Eocene/Oligocene transition (EOT), the Miocene Climate Optimum (MCO), the Pliocene peak warmth, and Ocean Anoxic events.
