Summary: | The Integrated Ocean Drilling Program Expedition 318 to the Wilkes Land margin of Antarctica recovered a sedimentary succession ranging in age from lower Eocene to the Holocene. Excellent stratigraphic control is key to understanding the timing of paleoceanographic events through critical climate intervals. Drill sites recovered the lower and middle Eocene, nearly the entire Oligocene, the Miocene from about 17 Ma, the entire Pliocene and much of the Pleistocene. The paleomagnetic properties are generally suitable for magnetostratigraphic interpretation, with well-behaved demagnetization diagrams, uniform distribution of declinations, and a clear separation into two inclination modes. Although the sequences were discontinuously recovered with many gaps due to coring, and there are hiatuses from sedimentary and tectonic processes, the magnetostratigraphic patterns are in general readily interpretable. Our interpretations are integrated with the diatom, radiolarian, calcareous nannofossils and dinoflagellate ... : Supplement to: Tauxe, Lisa; Stickley, Catherine E; Sugisaki, Saiko; Bijl, Peter K; Bohaty, Steven M; Brinkhuis, Henk; Escutia Dotti, Carlota; Flores, José-Abel; Houben, Alexander J P; Iwai, Masao; Jiménez-Espejo, Francisco Jose; McKay, Robert M; Passchier, Sandra; Pross, Jörg; Riesselman, Christina R; Röhl, Ursula; Sangiorgi, Francesca; Welsh, Kevin; Klaus, Adam; Fehr, Annick; Bendle, James A; Dunbar, Robert G; Gonzales, J; Hayden, Travis; Katsuki, Kota; Olney, Matthew P; Pekar, Stephen F; Shrivastva, P K; van de Flierdt, Tina; Williams, Thomas; Yamane, Masako (2012): Chronostratigraphic framework for the IODP Expedition 318 cores from the Wilkes Land Margin: Constraints for paleoceanographic reconstruction.
