We are grateful to the Leg 178 shipboard party and others who have contributed to this volume for their many insights and contributions to understanding Antarctic climate history. This synthesis is based on research that used samples and data provided by the Ocean Drilling Program (ODP), from sites proposed by ANTOSTRAT members, and reviewed by an ODP Detailed Planning Group and ODP Advisory Panels. ODP is sponsored by the U.S. National Science Foundation (NSF) and participating countries under management of Joint Oceanographic Institutions (JOI), Inc. Participation of A. Camerlenghi in this leg was supported by a grant from Programma Nazionale di Ricerche in Antartide (PNRA). The manuscript has benefitted from the comments of Carol Pudsey, Gary Acton, Alan Cooper, and John Anderson.
