We warmly thank the technicians for their assistance during the core laboratory work, and the staff and drilling crews aboard the JOIDES Resolution for their cooperation. We are especially indebted to Myung Lee, for providing us the MCS data used in this study. Thanks are also due to Maurizio Marchi and Carla De Cillia for preliminary seismic data processing. Warren Wood, Steve Holbrook, William Dillon, and two anonymous reviewers provided valuable advice and thoughtful suggestions. This research was partially supported by the ODP-Italy grant from Prof. Maria Bianca Cita (University of Milano), and by the Italian Programma Nazionale di Ricerche in Antartide (PNRA).
