Warm intervals within the Pliocene epoch (5.33-2.58 million years ago) were characterized by global temperatures comparable to those predicted for the end of this century (Haywood and Valdes, doi:10.1016/S0012-821X(03)00685-X) and atmospheric CO2 concentrations similar to today (Seki et al., 2010, doi:10.1016/j.epsl.2010.01.037; Bartoli et al., 2011, doi:10.1029/2010PA002055; Pagani et al., 2010, doi:10.1038/ngeo724). Estimates for global sea level highstands during these times (Miller et al., 2012, doi:10.1130/G32869.1) imply possible retreat of the East Antarctic ice sheet, but ice-proximal evidence from the Antarctic margin is scarce. Here we present new data from Pliocene marine sediments recovered offshore of Adélie Land, East Antarctica, that reveal dynamic behaviour of the East Antarctic ice sheet in the vicinity of the low-lying Wilkes Subglacial Basin during times of past climatic warmth. Sedimentary sequences deposited between 5.3 and 3.3 million years ago indicate increases in Southern Ocean ... : Supplement to: Cook, Carys P; van de Flierdt, Tina; Williams, Trevor J; Hemming, Sidney R; Iwai, Masao; Kobayashi, Munemasa; Jiménez-Espejo, Francisco Jose; Escutia, Carlota; Gonzàlez, Jhon Jairo; Khim, Boo-Keun; McKay, Robert M; Passchier, Sandra; Bohaty, Steven M; Riesselman, Christina R; Tauxe, Lisa; Sugisaki, Saiko; Lopez Galindo, Alberto; Patterson, Molly O; Sangiorgi, Francesca; Pierce, Elizabeth L; Brinkhuis, Henk; Klaus, Adam; Fehr, Annick; Bendle, James A; Bijl, Peter K; Carr, Stephanie A; Dunbar, Robert B; Flores, José-Abel; Hayden, Travis G; Katsuki, Kota; Kong, Gee Soo; Nakai, Mutsumi; Olney, Matthew P; Pekar, Stephen F; Pross, Jörg; Röhl, Ursula; Sakai, Toyusaburo; Shrivastava, Prakash Kumar; Stickley, Catherine E; Tuo, Shouting; Welsh, Kevin; Yamane, Masako (2013): Dynamic behaviour of the East Antarctic ice sheet during Pliocene warmth.
